Abstract
The utility model relates to a full premix catalytic combustion wall-mounted boiler, which comprises a gas control valve, a controller, a main heat exchanger assembly, a burner, a gas pipe, a control transmission line, a mixer, a fan, a fume extractor, a combustion chamber, a water pipe, a water control valve, a heating water inlet, a heating water outlet, an air inlet and an outer shell, the main technical characteristics of the boiler are that the burner is a flat plate type burner of a ceramic plate, whose surface is coated with rare earth catalyst. The boiler is characterized in that harmful pollutants which are generated by burning NOx, CO and the like are effectively reduced, the boiler is beneficial to protect environment, the structure is simple, the boiler is easy to implement and the like.
Description
Technical field: the utility model relates to a kind of family expenses wall hanging stove, particularly a kind of wall hanging stove that adopts full premix catalytic combustion.
Background technology: the wall hanging stove of now general family expenses mainly comprises three component parts: combustion system, heating system and control system.Its course of work is the heating water that enters the wall hanging stove, flow through behind the water control valve, enter heat exchanger, the ignition controller igniting, gas-flow enters burner through pneumatic control system, combustion gas is lighted by pulsed discharge, form stable flame, combustion gas is completing combustion in the combustion chamber, produces high-temperature flue gas, when high-temperature flue gas is flowed through heat exchanger, cold heating water is heated to be the heating water of required heat.At present, the used burner of family expenses wall hanging stove generally can be divided into two kinds by combustion system: atmospheric burner, fully-premixed burner.Full premix combustion wall hanging stove,, is developed full premix catalytic combustion wall hanging stove for overcoming these defectives defectives such as environment pollute because the restriction of its structure causes the noxious pollutants such as NOx, CO of its burning generation higher.
Summary of the invention: technical problem to be solved in the utility model is that a kind of full premix catalytic combustion wall hanging stove will be provided, and it can reduce the noxious pollutants such as NOx, CO that burning produces effectively, helps environmental protection, and easy realization simple in structure.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises gas control valve, controller, main heat exchanger assembly, burner, appendix, control transmission line, blender, blower fan, fume extractor, combustion chamber, water pipe, water control valve, heating water inlet, heating water out, air inlet, shell, and described burner scribbles the flat ceramic wafer burner of rare earth catalyst for the surface.
Described rare earth catalyst (10) is CeO
2
Described rare earth catalyst (10) is a lanthana.
The utility model is compared the beneficial effect that is produced with prior art:
1, because the utility model adopts the surface to scribble the structure of the flat ceramic wafer burner of rare earth catalyst,, help environmental protection so it can reduce the noxious pollutants such as NOx, CO that burning produces effectively, and easy realization simple in structure.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structure enlarged drawing of burner 4 among Fig. 1.
The specific embodiment: shown in accompanying drawing 1, accompanying drawing 2, present embodiment comprises that fume extractor 9, main heat exchanger assembly 3, burner 4, combustion chamber 11, gas control valve 1, blender 7, heating water inlet 14, heating water out 15, controller 2, water control valve 13, blower fan 8, water pipe 12, control transmission line 6, appendix 5, air inlet 16 and shell 17 constitute.Wherein main heat exchanger assembly 3, the heating water inlet 14, the heating water out 15, water control valve 13, be connected by water pipe 12.Controller 2 links to each other with gas control valve 1, water control valve 13, blower fan 8 by control transmission line 6, is used to control the wall hanging furnaceman and does.Gas control valve 1, blender 7, air inlet 16 are connected by appendix 5; Blower fan 8, blender 7, catalytic burner 4, combustion chamber 11, fume extractor 9, main heat exchanger assembly 3 are connected.Burner 4 (can be CeO for being coated with rare earth catalyst 10
2Or lanthana etc.) flat ceramic wafer burner.
When starting the wall hanging stove, water flows through water control system 13 by heating water inlet 14, and water control valve 13 sends signal and gives controller 2, and water flows into main heat exchanger assembly 3; After controller 2 is received the signal of water control valve 13, controller 2 control blower fans 8 rotate, controller 2 sends the electric pulse igniting, after open pneumatic control system 1, combustion gas enters blender 7 and air through gas control valve 1 and mixes the back and lighted by electric pulse at flat ceramic wafer burner 4, the high-temperature flue gas of combustion gas through producing behind rare earth catalyst 10 catalytic combustions discharged from fume extractor 9 after main heat exchanger 3 coolings, simultaneously, the heating current are heated behind main heat exchanger assembly 3, flow out through heating water out 15.
