Definitions

  • the present invention relates to a total premix gas/air burner (also called “premix burner”).
  • Total air/gas premix burners are currently known to be widely employed to produce thermal energy in gas boilers.
  • [A] have lower polluting substance emissions (nitrogen and carbon oxides);
  • [B] have high thermal exchange efficiencies at all thermal power rates, and in particular at minimum thermal power;
  • [C] have high modulation ranges between maximum and minimum thermal power of the burner.
  • premix air/gas burners are mainly made using the following essential components:
  • the “active device” (also called “driver”) is represented by the fan which, electrically fed in an appropriate manner, provides comburent air to the burner in amount directly proportional to the thermal power that is intended to be provided to the burner, and thus to the thermal power of the burner head.
  • the passive device (also called “follower”) is represented by the gas valve, which is capable of providing gas in amount directly proportional to the amount of air blown into the system by virtue of the regulation system illustrated thereinafter.
  • Gas valves are normally characterized in that, independently from the inlet gas pressure (obviously within the working limits allowed by the valve itself and corresponding to the network gas distribution pressures), they provide output gas at a pressure equal to the pressure exerted on their “regulator” except for a difference called “offset” value, adjustable by acting on the valve.
  • offset a difference between the pressure exerted on their “regulator” except for a difference called “offset” value, adjustable by acting on the valve.
  • the present premix burner was designed to solve these drawbacks and must be considered as a further evolution of the premix burner described and claimed in aforesaid international application WO2009/0133451.
  • the minimum thermal flow rate i.e. the flow rate in which offset variations of the gas valve correspond to greater air/gas ratio variations, will be taken as reference in order to explain the behavior of the system described in international application WO2009/0133451.
  • the plug Independently from the offset value set in the gas valve, as the air/gas mixture flow rate aspirated the fan increases the plug starts opening allowing also its venturi channel to generate vacuum, gradually attenuating the phenomena illustrated above to can them out completely and to provide its contribution of the air/gas mixture flow rate with respective ratio values always closer to the reference value which is found at maximum thermal flow rate.
  • the present invention is advantageously but not exclusively applied in combination with a combined boiler for the simultaneous or delayed production of heating water and domestic hot water.
  • FIG. 1 schematically shows a first embodiment of a premix burner according to the present invention; in this case, the burner is arranged vertically with the fan delivering and in a rest configuration;
  • FIG. 2 shows the same burner of FIG. 2 , this time, however, in an overflow configuration
  • FIG. 3 shows the same burner illustrated in FIGS. 1 , 2 in a maximum flow rate configuration
  • FIG. 4 schematically shows a second embodiment of a premix burner according to the present invention; in this case, the burner is arranged vertically with the fan aspirating and in a rest configuration;
  • FIG. 5 shows a third embodiment of a burner according to the invention; in this case, the burner is arranged horizontally, the fan is aspirating and in a rest configuration; and
  • FIG. 6 shows a fourth embodiment of a burner according to the invention; in this case, the burner is arranged horizontally, the fan is delivering and in a rest configuration.
  • a venturi channel air/gas mixer 11 is placed downstream of a fan 12 with respect to an air flow (AF).
  • the mixer 11 comprises a localized pressure loss device 11 A, in this case constituted by a venturi channel tube.
  • the burner 10 has a substantially longitudinal symmetry plane (X).
  • a pipe 13 which carries a pressure signal P 1 to a gas valve 14 , is connected upstream of the venturi channel type air gas mixer 11 . Furthermore, a gas flow (GF) enters into the gas valve 14 at network pressure Po.
  • GF gas flow
  • the amount of gas released by the gas valve 14 towards the mixer 11 is correlated to the pressure difference existing between an output pressure P 2 of the gas valve 14 (pressure P 2 equal to the pre-sure value P 1 ) and a pressure P 3 existing in the narrowest point (the localized loss of pressure device 11 A) of the venturi channel type air/gas mixer 11 .
  • the regulation of the air/gas ratio is mainly entrusted to the size of the nozzles (UG 1 ) (UG 2 ), and secondarily to the adjustment of the flow regulator 15 .
  • Each gas inlet point in the localized pressure drop device 11 A is equipped, respectively, with a respective nozzle (UG 1 ), (UG 2 ); according to needs, such nozzles (UG 1 ), (UG 2 ) may be equivalent or different to each other.
  • a tube 16 forks into two pipes 16 A, 16 B, each of which feeds a respective nozzle (UG 1 ), (UG 2 ) with gas after the flow regulator 15 , a tube 16 forks into two pipes 16 A, 16 B, each of which feeds a respective nozzle (UG 1 ), (UG 2 ) with gas.
  • the flow regulator 15 placed on the connection tube 16 between gas valve 14 and venturi channel type air/gas mixer 11 allows to accurately adjust the amount of gas supplied so as to have an optimal air/gas ratio for mixture combustion in a combustion head (TC).
  • the system allows to obtain a constant air/gas ratio throughout the entire working range of the burner 10 .
  • the air/gas mixture is sent towards the combustion head (TC).
  • the burner 10 is completed by an ignition and flame presence detection device 17 and by an electronic control unit (CNT) which controls the working of the fan 12 , of the gas valve 14 , and of the device 17 itself.
  • CNT electronic control unit
  • a characterizing element of the embodiment shown in FIG. 1 is constituted in that the venturi channel type air/gas mixer 11 is split into two channels (CH 1 ), (CH 2 ) by a flow divider 18 .
  • the size of the minimum sections of the mixing channels (CH 1 , CH 2 ) of the fluids are equal to each other so as to generate the same pressure difference, the through air flow being equal.
  • the size of the minimum section of the mixing channels (CH 1 ), (CH 2 ) of the fluids may be different so as to provide a different, predetermined pressure difference, the through air flow being equal.
  • Such flow divider 18 is formed so as to confer to each channel (CH 1 ), respectively, (CH 2 ) the shape of a venturi channel with passage sections which may be circular or non-circular.
  • venturi shaped channel (CH 1 ) is closed, according to laws which will be seen in greater detail below by a first plug 19 coupled to a wall (WL) of the burner 10 by means of a respective hinge (HG 1 ).
  • a second plug 20 hinged to the flow divider 18 by means of a respective hinge (HG 2 ) has been added in order to further decrease the negative effects consequent to the offset variation.
  • the second plug 20 is also positioned at the channel (CH 1 ) and at the nozzle (UG 1 ), so that in the rest condition shown in FIG. 1 , the second plug 20 completely surrounds such a nozzle (UG 1 ) and does not allow the gas to flow from the tube 16 to the channel (CH 1 ).
  • the second plug 20 has a barycentre (C) which moves upwards by effect of the thrusts of the air/gas mixture transiting towards the channel (CH 1 ) ( FIGS. 2 , 3 ).
  • the pressure in the common pipe 16 A of the gas circuit is lower than the air pressure at the venturi channel type air/gas mixer 11 inlet.
  • the amount or air which thus enters into the gas pipe 16 A dilutes the gas which is entering through the pipe 16 B into the channel (CH 2 ) free from the first plug 19 .
  • the pressure in the common pipe 16 A is higher than the air pressure at the venturi channel type air/gas mixer 11 inlet.
  • the plug 19 starts opening also allowing its venturi channel to generate vacuum, gradually attenuating the phenomena illustrated hereinbefore to cancel them out completely and to provide its contribution to the air/gas mixture flow rate with respective ratio values always closer to the reference value which is found at maximum thermal flow rate.
  • the operation of the premix burner 10 is as follows:
  • premix burners object of international application WO2009/0133451 by the same Applicant, indifferently operate with their axis arranged vertically or horizontally and, for each of these solutions, they may be placed with the fan either aspirating or delivering.
  • FIGS. 4 , 5 , 6 They are illustrated in the present FIGS. 4 , 5 , 6 .
