Definitions

  • the heating appliance can be equipped with a chamber with a secondary airflow or a water coil which, in contact with the combustion exhaust fumes, transfers some of the heat of the aforesaid fumes to the vector fluid, thus increasing the appliance's thermal performance (for example as described in the V199A000243 and VI2004A000049 patents).
  • the object of the present finding is to make a combustion heating appliance which can function with a considerably improved energy performance and lowered pollution emissions with respect to similar products of known type.
  • a device to be mounted downstream of a biomass burner present in wood, pellet, wood chips, oil seeds and generally biomass heaters/boilers, which comprises at least one impregnated, monolithic honeycomb catalyst, at least one heat exchanger, at least one electrostatic filter and at least one suction device, which has the function of generating a depression along the fumes path (burner - catalyst - heat exchanger - filter) to facilitate their elimination from the appliance.
  • the device of the finding is substantially made up of a post-burner positioned downstream of the combustion chamber of the heating appliance, as it must collect burnt gases while they are still flames and at temperatures not below 300-350°C, the limit value for being able to neutralise the substances by means of the catalyst.
  • the catalyst has the task of converting harmful substances into harmless substances by means of chemical reactions where noble metals such as platinum and palladium cause the oxidation of carbon monoxide and unburnt hydrocarbons, converting them into carbon dioxide and water (environmental function).
  • noble metals such as platinum and palladium cause the oxidation of carbon monoxide and unburnt hydrocarbons, converting them into carbon dioxide and water (environmental function).
  • the positioning of the heat exchanger, after the catalyst, allows achieving a high performance, since the hot gases coming from the combustion stage - though collected directly above the burner and thus containing high quantities of harmful substances - due to the post-combustion achieved with aforesaid the catalyst are free of fumes containing ashes at the outlet of the catalyst itself. If said ashes still present during the use, they would disadvantageously deposit on the inner walls of the exchanger, thus reducing its performance or thermal conduction towards the outside.
  • the finding moreover provides that the exchanger be positioned such that a first part thereof at the base of the tube bundle is touched by the combustion flames, which causes the immediate and complete evaporation of possible condensate that is formed on the bottom of the aforesaid exchanger.
  • the gases exiting from the exchanger at low temperatures pass through an electrostatic chamber where they undergo a filtration process which retains any dusts and fumes generated by poor post-combustion due to an irregular functioning of the heating appliance, such as a sudden temperature drop inside the catalyst, or during the burner turning on/off steps.
  • a suction device is mounted at the end of the exhaust gas pipe where the fumes have completely cooled down.
  • Such suction device is used to place the entire channel which defines the whole exhaust gas path under reduced pressure (catalyst/heat exchanger/electrostatic chamber), so to initiate the suction operation directly from the heating appliance combustion chamber.
  • FIGS. 1-3 illustrate three views, respectively one front and two side views, of the device according to the finding mounted on a heating appliance;
  • FIGS. 4-5 (table II) illustrate two views, respectively front and side, of the device according to the finding;
  • FIG. 6-7 (table III) illustrate two views, front and side, of the front part of the device according to the finding;
  • FIGS 10-12 illustrate three orthogonal views of the air conveying device.
  • the economiser/environmentally-friendly device according to the finding, indicated as 1 is mounted on the combustion chamber "C" of a standard heating appliance, not illustrated for simplification reasons.
  • the device 1 is characterised in that it provides for the use of four components: a catalyst 2, a first heat exchanger 3, a second heat exchanger 4, an electrostatic filter 5 and a suction device 6.
  • the previously mentioned components are positioned in sequence along the exhaust gas route, from the combustion chamber "C” to the exhaust pipe "S". Furthermore, said components are connected with each other through pipes, respectively pipe 7 connecting the catalyst 2 to the first exchanger 3, pipe 8 connecting the first exchanger 3 to the second exchanger 4 and pipe 9 connecting the electrostatic filter 5 to the final suction device 6.
  • the device 1 provided for by this invention operates in two steps: there is the first step where post-combustion of exhaust gases occurs and where a considerable heat exchange activity between said gases and the environment takes place; then, a second step closely follows where the heat exchange activity is completed and the exhaust gases filtering operations are performed.
  • a post-combustion process occurs in the catalyst 2 - preferably of ceramic, monolithic honeycombed type and impregnated with noble metals - so that not only are the exiting gases "G2" free of harmful substances but they also reach a temperature of approximately 800°C.
  • gases enter into the heat exchanger 3 where, in contact with the tube bundle 3.1, the first heat exchange with the environment occurs through air or water circulation.
  • the finding provides that the base 3.2 of the exchanger 3 faces the combustion chamber "C", so to be able be touched by the combustion flames, so that the possible condensate which is formed on the tube bundle 3.1 is collected at the base 3.2 and vaporised completely by the heat (see arrows) generated by the combustion chamber.
  • the gases "G3", still hot and dry, exiting from the exchanger 3 and collected by the channel 3.3, are conveyed through pipe 8 into the second exchanger 4 where, in contact with the tube bundle 4.1, a second heat exchange with the environment occurs through air or water circulation.
  • Gases "G4", already cooled to low temperature at this point, at the outlet of the tube bundle pass through the electrostatic filter 5, comprising at least one ionising chamber 5.1 and at least one collection chamber 5.2, which remove all residual pollutant dusts from the aforesaid gases.
  • an air conveying apparatus generally indicated as 10, on the first exchanger 3.
  • Said air conveying device 10 comprises at least a covering 10.1 coupled with an electric fan 10.2 - which draws air from the outside and sends it into the tube bundle 3.1 - and an outlet grate 10.3.
  • thermal exchange may occur through a water (or any other liquid) forced circulation system by means of a hydraulic pump.
