Definitions

  • This invention relates to a method for supplying combustion air to a melting furnace of gasification melting equipment.
  • Gasification melting equipment is at the very core of a gasification melting facility, generally comprising a gasification furnace that performs pyrolysis of waste such as municipal solid waste and industrial waste to produce a produced gas (pyrolysis gas and char), and a melting furnace having an introduction port through which the produced gas is introduced into the melting furnace through a gas duct linked to the gasification furnace: the pyrolysis gas (combustible gas) in the produced gas is combusted in the melting furnace to melt the ash in the produced gas into a molten slag.
  • a gasification furnace that performs pyrolysis of waste such as municipal solid waste and industrial waste to produce a produced gas (pyrolysis gas and char)
  • a melting furnace having an introduction port through which the produced gas is introduced into the melting furnace through a gas duct linked to the gasification furnace: the pyrolysis gas (combustible gas) in the produced gas is combusted in the melting furnace to melt the ash in the produced gas into a molten slag.
  • this type of gasification melting equipment comprises a melting furnace 80 with a primary combustion chamber 82 having an upper inner wall (i.e., an inner wall at the top of the melting furnace 80) to which a clinker 84 tends to adhere.
  • This clinker 84 grows to prevent maintaining the produced gas retention time necessary for proper combustion of the produced gas introduced from the gas duct 86 into the primary combustion chamber 82, thus decreasing combustion efficiency, or prevent maintaining a proper shape of the primary combustion chamber 82 for the swirling produced gas flow in the primary combustion chamber to decrease the slag conversion rate (the trapping of ash contained in the produced gas).
  • the gasification melting equipment has a risk that the clinker 84 having grown will block off the primary combustion chamber 82, or fall to damage the melting furnace 80 or block off the slag discharge hole.
  • Patent JP2003-4212 There is conventionally described a technique for preventing an adherence of clinker in a melting furnace of gasification melting equipment as discussed above in Patent JP2003-4212 .
  • the melting furnace discussed in Patent JP2003-4212 comprises a side wall and a ceiling wall that constitute a primary combustion chamber, and a plurality of combustion gas supply nozzles each having an opened tip and being provided to the side wall and ceiling wall.
  • the combustion gas supply nozzles blow combustion gas (combustion air) therefrom into the primary combustion chamber, thereby promoting mixing of the combustion gas and produced gas for quick temperature rise to prevent clinker from adhering to the upper inner wall of the primary combustion chamber of the melting furnace.
  • This melting furnace however, has room for improvement of the locations of the combustion air supply nozzles for supplying combustion air for primary combustion in the melting furnace, in order to prevent the clinker from adhering to the upper inner wall of the primary combustion chamber of the melting furnace.
  • Document WO 02/086405 discloses a method for supplying combustion air to a melting furnace of a gasification melting equipment according to the preamble of claim 1.
  • the present invention provides a method for supplying combustion air to a melting furnace of gasification melting equipment, according to claim 1.
  • the first combustion air supply nozzles which are provided to the gas duct at positions near the produced gas introduction port provided to the upper side wall of the primary combustion chamber of the melting furnace, supply at least 70% of the total amount of combustion air supplied to the primary combustion chamber of the melting furnace: the produced gas and the combustion air supplied from the first combustion air supply nozzles, which air accounts for the majority of the total amount of combustion air, can be mixed in a state that the calorific power of the produced gas led from the gasification furnace through the gas duct to the primary combustion chamber is high. This makes it possible to raise the internal furnace temperature at the upper part of the primary combustion chamber of the melting furnace over the melting temperature of the ash contained in the produced gas to prevent clinker from adhering to the upper inner wall of the primary combustion chamber of the melting furnace.
  • Fig. 1 is a diagram of the overall configuration of the gasification melting equipment pertaining to an embodiment of the present invention.
  • the gasification melting equipment 10 shown in Figs. 1 to 5 comprises a fluidized bed gasification furnace 20, a swirling flow melting furnace 30, and a gas duct 40.
  • a produced gas B containing pyrolysis gas and char is produced by pyrolysis of waste A.
  • the swirling flow melting furnace 30 has a produced gas introduction port 33, through which the produced gas B from the fluidized bed gasification furnace 20 is introduced into the swirling flow melting furnace 30.
  • the pyrolysis gas (combustible gas) in the produced gas B is combusted, while the ash in the produced gas B is converted into molten slag.
  • the gas duct 40 links the fluidized bed gasification furnace 20 and the swirling flow melting furnace 30 to lead the produced gas B produced in the fluidized bed gasification furnace 20 to the produced gas introduction port 33 of the swirling flow melting furnace 30.
  • the swirling flow melting furnace 30 has a primary combustion chamber 31 and a secondary combustion chamber 32.
  • the produced gas B from the fluidized bed gasification furnace 20 is supplied through the gas duct 40 to the primary combustion chamber 31 of the swirling flow melting furnace 30 to form a swirling flow within the primary combustion chamber 31.
  • the primary combustion chamber 31 has a ceiling wall, which has a top provided with a second combustion air supply nozzle 34 (one is depicted).
  • the second combustion air supply nozzle 34 has an opened tip to blow combustion air f2 into the primary combustion chamber 31 from the tip.
  • Figs. 2 to 4 show the main components of the gas duct 40 and the swirling flow melting furnace 30: Fig. 2 is a plan view; Fig. 3 is a side view along the arrow III in Fig. 2 ; and Fig. 4 is a side view along the arrow IV in Fig. 2 .
  • the produced gas introduction port 33 is placed in the upper side wall of the primary combustion chamber 31 of the swirling flow melting furnace 30, and the gas duct 40 is connected to this produced gas introduction port 33.
  • the gas duct 40 is provided with a plurality of (six are depicted) first combustion air supply nozzles 41a to 41c and 42a to 42c, at positions near the produced gas introduction port 33.
  • Each of the first combustion air supply nozzles 41a to 41c and 42a to 42c has an opened tip to blow combustion air f1 from the tip into the primary combustion chamber 31, being placed in an attitude inclined along the flow direction of the produced gas B (see Fig. 2 ).
  • first combustion air supply nozzles 41a to 41c are provided to the outer side wall 43 of the gas duct 40 so as to be vertically aligned and supply combustion air from the outer side wall 43 while being inclined along the flow direction of the produced gas B.
  • first combustion air supply nozzles 42a to 42c are provided in the inner side wall 44 of the gas duct 40 so as to be vertically aligned and supply combustion air from the inner side wall 44 while being inclined along the flow direction of the produced gas B.
  • Fig. 5 is a cross section along the V-V line in Fig. 3 .
  • the first combustion air supply nozzle 41a is provided so as to blow the combustion air f1 toward the intersection point P1 of the produced gas introduction port 33 and the duct width center line CL of the gas duct 40 near the produced gas introduction port 33 in plan view, in order to raise the temperature inside the furnace (the temperature inside the chamber) at the upper part of the primary combustion chamber 31.
  • the nozzle 41a is positioned so that an extension of the axis of the first combustion air supply nozzle 41a in plan view passes through the intersection point P1.
  • the temperature could rise inside the gas duct 40 to allow clinker to block off the gas duct 40.
  • the first combustion air supply nozzle 41a were placed so as to blow the combustion air f1 toward a location downstream from the point of intersection P1 in plan view (such as a point P3), the combustion time during which the produced gas B mixed with the combustion air should be collided with the inner wall of the primary combustion chamber 31 could be so insufficient that the effect of raising the internal furnace temperature of the upper part of the primary combustion chamber 31 could not be easily obtained.
  • the combustion time during which the produced gas B mixed with the combustion air should be collided with the inner wall of the primary combustion chamber 31 could be so insufficient that the effect of raising the internal furnace temperature of the upper part of the primary combustion chamber 31 could not be easily obtained.
  • the combustion air f1 could hinder the swirling flow in the primary combustion chamber 31 to lower the slag conversion ratio (ash capture ratio).
  • the first combustion air supply nozzle 41a is so placed as to blow the combustion air f1 toward the intersection point P1 of the produced gas introduction port 33 and the duct width center line CL in plan view, as mentioned above.
  • the combustion air supply nozzles 41a to 41c pertaining to this embodiment are provided to the side wall 43 of the gas duct 40 at an outer side of the duct width center line CL, and disposed so as to blow combustion air from the side wall 43 toward the point of intersection P1, while the combustion air supply nozzles 42a to 42c are provided to the side wall 44 of the gas duct 40 at an inner side of the duct width center line CL, and disposed so as to blow combustion air from this side wall 44 toward the point of intersection P1.
  • the swirling flow melting furnace 30 is adapted to supply combustion air for the primary combustion chamber of the swirling flow melting furnace 30 only from the first combustion air supply nozzles 41a to 41c and 42a to 42c placed in the gas duct 40 at positions near the produced gas introduction port 33 provided to an upper side wall of the primary combustion chamber 31 of the swirling flow melting furnace 30, and from the second combustion air supply nozzle 34 placed in the ceiling wall of the primary combustion chamber 31.
  • the ratio is set such that the first combustion air supply nozzles 41a to 41c and 42a to 42c supply at least 70% of the total amount of combustion air supplied to the primary combustion chamber 31.
  • Fig. 6 is a graph of the relation between the allocation ratio ⁇ of the amount of combustion air supplied by the first combustion air supply nozzles provided to the gas duct 40 with respect to the total amount of combustion air for the primary combustion chamber of the swirling flow melting furnace 30, and the internal furnace temperature T at the upper part of the primary combustion chamber.
  • the allocation ratio ⁇ of 46% resulted in a measured value for the internal furnace temperature T of 1015°C to 1149°C (average of 1082°C) ; the allocation ratio ⁇ of 63% resulted in a measured value for the internal furnace temperature T of 1154°C to 1198°C (average of 1176°C); and the allocation ratio ⁇ of 84% resulted in a measured value for the internal furnace temperature T of 1165°C to 1238°C (average of 1201°C).
  • the allocation ratio ⁇ of at least 70% permits the internal furnace temperature T at the upper part of the primary combustion chamber to be raised over 1200°C that is higher than the melting point of the ash contained in char.
  • the results shown in Fig. 6 taught us that the allocation ratio ⁇ should be set to at least 70%.
  • the amount of the combustion air in the fluidized bed gasification furnace 20 (the amount of forced air E shown in FIG. 1 ) and the amount of combustion air for the primary combustion chamber supplied from the first combustion air supply nozzles 41a to 41c and 42a to 42c and the second combustion air supply nozzle 34 are both favorably from 1.0 to 1.2 in terms of the air ratio (the air ratio is the ratio of the amount of supplied air to the minimum amount of air required for completely combusting the combustibles in the waste serving as the raw material).
  • the air ratio is the ratio of the amount of supplied air to the minimum amount of air required for completely combusting the combustibles in the waste serving as the raw material.
  • the speed of the produced gas supplied from the fluidized bed gasification furnace 20 to the swirling flow melting furnace 30 is set to 15 to 25 m/s (preferably 18 to 20 m/s). While the high supply speed is preferable, the excessively high speed let the collision pressure against the inner wall of the primary combustion chamber 31 of the swirling flow melting furnace 30 rise excessively to cause the adhesion of clinker: therefore, the speed is controlled no higher than the above maximum of 25 m/s.
  • the forced air E which is forced-introduced from the lower portion of the furnace bed fluidizes a fluid media C such as sand with to form a fluidized bed. Then, waste A is thrown into the fluidized bed gasification furnace 20 and pyrolyzed (gasified) in the fluidized bed. Non-combustibles D contained in the waste A and not gasified are discharged out of the furnace from the lower portion of the fluidized bed.
  • the produced gas B (pyrolyzed gas and char) produced in the fluidized bed gasification furnace 20 is led through the gas duct 40 to the produced gas introduction port 33 of the swirling flow melting furnace 30.
  • This produced gas B while mixed with the combustion air f1 for the primary combustion chamber supplied from the first combustion air supply nozzles 41a to 41c and 42a to 42c placed to the gas duct 40 at positions near the produced gas introduction port 33, is introduced from the produced gas introduction port 33 into the primary combustion chamber 31 of the swirling flow melting furnace 30, thereby forming a swirling flow in the primary combustion chamber 31.
  • the produced gas G is mixed with the combustion air f2 for the primary combustion chamber supplied from the second combustion air supply nozzle 34 placed in the ceiling wall of the primary combustion chamber 31, thus being combusted in the primary combustion chamber 31.
  • the combustion airs f1 and f2 for the primary combustion chamber at least 70% (such as 75%) of the total amount of combustion air for the primary combustion chamber of the swirling flow melting furnace 30 is supplied by the first combustion air supply nozzles 41a to 41c and 42a to 42c.
  • This method makes it possible to mix the produced gas B, which is led from the gasification furnace 20 to the primary combustion chamber 31 through the gas duct 40 and has a high calorific power, and the combustion air f1 supplied from the first combustion air supply nozzles 41a to 41c and 42a to 42c, which air accounts for the majority of the total amount of combustion air, thus allowing the produced gas B to be combusted all at once.
  • This makes it possible to raise the internal furnace temperature at the upper part of the primary combustion chamber 31 over 1200°C, the melting point of the ash contained in char, to prevent clinker from adhering onto the upper inner wall of the primary combustion chamber 31.
  • the melted ash flows down the inner wall of the primary combustion chamber 31, and flows down the bottom of the swirling flow melting furnace (slag separation component) along with the ash melted in the lower portion of the primary combustion chamber 31, thus discharged to the outside through a slag tap hole 35, as molten slag H.
  • the produced gas led from the primary combustion chamber 31 to the secondary combustion chamber 32 is mixed with combustion air G for the secondary combustion chamber and completely combusted in the secondary combustion chamber 32.
  • Flue gas J that has undergone complete combustion in the secondary combustion chamber 32 is discharged from the swirling flow melting furnace 30, and is released into the atmosphere through a heat recovery device, bag filter, and so forth.
  • the method for supplying combustion air to the melting furnace of gasification melting equipment makes it possible to prevent clinker from adhering onto the upper inner wall of the primary combustion chamber 31 of the swirling flow melting furnace 30. Accordingly, there can be prevented a damage of the swirling flow melting furnace 30 or a block off of the slag tap hole 35 due to dropped clinker, block off of the primary combustion chamber 31 of the swirling flow melting furnace 30 due to the growth of clinker, and a decrease in combustion efficiency and a decrease in the slag conversion ratio due to the adhesion or growth of clinker. As a result, stable operation of the gasification melting equipment 10 in the proper state can be carried out over an extended period.
  • the method for supplying combustion air to the melting furnace of gasification melting equipment pertaining to the present invention providing first combustion air supply nozzles to a gas duct near a produced gas introduction port provided to an upper side wall of the primary combustion chamber of the melting furnace and supplying at least 70% of the total amount of combustion air supplied to the primary combustion chamber of the melting furnace from these nozzles make it possible to mix the produced gas, which is led from the gasification furnace through the gas duct to the primary combustion chamber and has a high calorific power of the produced gas, and the combustion air supplied from the first combustion air supply nozzles, which air accounts for the majority of the total amount of combustion air, thereby raising the internal furnace temperature at the upper part of the primary combustion chamber of the melting furnace over the melting temperature of the ash contained in the produced gas to prevent clinker from adhering onto the upper inner wall of the primary combustion chamber of the melting furnace.
  • the first combustion air supply nozzles are placed so as to blow the combustion air toward the intersection point of the produced gas introduction port and the duct width center line of the gas duct near the produced gas introduction port in plan view. This makes it possible to prevent the rise of the temperature in the gas duct and block off of the gas duct by clinker, while ensuring sufficient combustion time during which the produced gas containing the combustion air collides with the inner wall of the primary combustion chamber to raise the internal furnace temperature at the upper part of the primary combustion chamber.
  • the first combustion air supply nozzles are preferably placed in the gas duct in an attitude for blowing combustion air toward the intersection point while inclined along the duct width center line. This enables combustion air to be smoothly supplied from the nozzles to the primary combustion chamber.
  • the first combustion air supply nozzles include a nozzle that is placed in a side wall of the gas duct at an outer side of the duct width center line and blows combustion air from the side wall toward the intersection point, and a nozzle that are placed in a side wall of the gas duct at an inner side of the duct width center line and blows combustion air from the side wall toward the intersection point.
  • This enables a sufficient quantity of combustion air to be supplied from both side walls of the gas duct toward the above-mentioned point of intersection.
  • the first combustion air supply nozzles are placed so as to supply combustion air while being inclined along the duct width center line, the combustion air supplied from the outer side wall and the combustion air supplied from the inner side wall have few elements interfering with each other.
  • combustion air may be supplied to the primary combustion chamber of the melting furnace by just the above-mentioned first combustion air supply nozzles and a second combustion air supply nozzle placed in a ceiling wall of the primary combustion chamber of the melting furnace.
