Definitions

  • the invention relates to a method for burning combustible material, in which combustible exhaust gases are fed to a combustion chamber.
  • the invention further relates to a combustion chamber for combusting the exhaust gases resulting from the implementation of the method and to special uses of the combustion chamber.
  • the exhaust gases When the exhaust gases are burnt, their complete burnout is desirable because of the generation of environmentally friendly residual gases.
  • the aim is to completely burn out the exhaust gases because of the improvement in the energy balance.
  • the object on which the invention is based is achieved according to the invention in that the exhaust gases are guided separately from within the combustion chamber to its outlet or its outlets and fresh air is added to the separately guided exhaust gases.
  • the separate routing of the exhaust gases - in conjunction with the easily controllable supply of fresh air to the separately guided exhaust gases - enables the temperatures required for complete combustion to be set within a defined range.
  • the rest of the combustion chamber can be kept at a lower temperature level, whereby the temperature load on the combustion chamber walls can be kept lower and further disadvantages, such as the melting of the ash, can be avoided. This is particularly the case with an expedient embodiment of the method according to the invention, in which the exhaust gases are led separately from the center of the combustion chamber or through the center of the combustion chamber.
  • the special guidance of the exhaust gases also enables particularly favorable starting conditions for the combustion chamber. If you ignite the exhaust gases in the delimited area of the separate guide, this area can very quickly be brought to the temperature required for the formation of clean residual gases, about 800 ° C.
  • a particularly advantageous variant of the method according to the invention consists in that the exhaust gases supplied to the combustion chamber are supplied with fresh air in a sub-stoichiometric ratio and additionally to the separately guided exhaust gases with fresh air in an at least stoichiometric ratio. This makes it possible - by appropriate dimensioning of the fresh air quantities - to optimally set the desired high temperatures in the delimited area of the separately guided exhaust gases and lower temperatures in the remaining area of the combustion chamber.
  • a combustion chamber is suitable for carrying out the method according to the invention, in which at least one penetrating or from the combustion chamber Interior of the combustion chamber outgoing gas guide line is provided with one or more openings to the combustion chamber, which forms at one end the outlet of the combustion chamber or is connected to it and which can be connected to a fresh air line.
  • the gas conduction line expediently consists of refractory material such as ceramic or refractory steel.
  • An expedient embodiment of the combustion chamber is that the gas guide line penetrates the center of the combustion chamber or extends from the center of the combustion chamber.
  • a simple embodiment of the combustion chamber according to the invention provides a gas conduit from a tube with side openings.
  • the lateral openings can face both the upper, the lateral part of the combustion chamber or the ash discharge.
  • the side openings are preferably turned toward the ash discharge in order to prevent fly ash or other dust particles from entering the gas duct as far as possible.
  • the gas guide line penetrates the interior of the combustion chamber and that the fresh air line can be connected to the end of the gas guide line opposite the outlet of the combustion chamber.
  • the fresh air supply can also take place, for example, through a fresh air line protruding into the gas guide line.
  • the choice of the entry point for the fresh air gives the possibility of the combustion process in in the combustion chamber or in the gas duct, in addition to controlling the fresh air quantities and also by choosing the location of the fresh air feed.
  • the feed point for example, the length of time that the exhaust gases remain in the part of the gas conduit located after the feed point can be taken into account.
  • the combustion chamber according to the invention can advantageously be used in a combustion system for combusting combustible material, in which combustible material is first pyrolyzed in a chamber provided for this purpose and the exhaust gases resulting from the pyrolysis are fed to the combustion chamber.
  • the use of the combustion chamber according to the invention enables a particularly good control of the combustion process taking place in the combustion chamber.
  • the separate routing of the exhaust gases in the combustion chamber results in a bundled flame jet that is directed beyond the area of the combustion chamber while at the same time burning the gas intensively.
  • the combustion chamber according to the invention can then be used in a particularly advantageous manner in a combustion system for burning combustible material a device for using the sensible heat is connected downstream of the combustion chamber.
  • a heating boiler of a heating system can be connected downstream of the combustion chamber, the flame jet coming from the gas guide line of the combustion chamber being directed at the heat exchanger of the boiler.
  • the combustion chamber 1 is connected downstream of a pyrolysis chamber 2. Both chambers are separated from one another by the lock element 3.
  • the gas guide line 4 is guided through the center of the combustion chamber 1.
  • a gas burner 5 is arranged, which serves to ignite the combustion process in the combustion chamber.
  • the fresh air line 6 is connected to the gas guide line 4.
  • combustible material is filled into the pyrolysis chamber 2 through the upper lock 7.
  • Gas burners 8 are used at the start of the pyrolysis process.
  • the combustible exhaust gases formed in the pyrolysis chamber are drawn down into the combustion chamber 1. They reach the gas guide line 4 through openings 9.
  • the openings 9 are arranged on the side of the gas guide line facing the ash discharge 10, that is to say downwards.
  • the fresh air introduced into the combustion chamber 1 via the lock 3 leads to the partial combustion of the combustible exhaust gases at a temperature in the part of the combustion chamber 1 lying outside the gas conduit 4, likewise of not more than 800 ° C.
  • fresh air is fed into the gas guide line 4 in at least a stoichiometric ratio to the exhaust gases. This results in complete combustion of the exhaust gases that have entered the gas guide line 4, at which a temperature of about 1100 ° C. is reached.
  • the fresh air line 6 projects in the form of an additional line section 6a into the gas guide line 4 beyond the center of the combustion chamber.
  • the feed point for the fresh air is thus in the vicinity of the outlet of the combustion chamber, as a result of which the area of complete combustion of the exhaust gases is also in the vicinity of the outlet of the combustion chamber and the hot flame formed thereby projects beyond the area of the combustion chamber.
  • the gas guide line 4 starts from the center of the combustion chamber 1.
  • the gas guide line is designed as a tube, the end of which is located in the combustion chamber is open to the combustion chamber. Fresh air is fed in by suction via the line section 6a projecting into the tube 4, which is open to the outside after the gas burner 5 has been folded down.
