Description
Technical field
The present invention relates to a kind of energy saving civil gas burning pot stove, specifically a kind of to be fired using porous media radiant heating
The energy saving civil gas burning pot stove of burner, the kitchen range top, pan bracket, reflecting plate and outer bottom band coating pot.
Background technology
Traditional civil gas stove is generally combustion gas and directly burns in an atmosphere, predominantly open firing, be divided into upper air inlet, under
Three kinds of air intake and full air intake, operation principle are that combustion gas is mixed with air by appendix, valve opening, gas valve core, induction tunnel, nozzle,
Into burner, burnt in cooking stove external environment by the flame that valve, fire cover and air secondary are mixed to form.
The atmospheric burning type that the burning of China's domestic gas pot and stove gaseous fuel is mainly characterized with free flame at present,
This traditional combustion gas full premix combustion have very thin free flame, its burning inevitable that temperature distributing disproportionation,
The shortcomings of combustion zone is narrow and small, the thermal efficiency is low, pollutant emission is high.This heat conductivility and radiance mainly due to gas
Poor, gas flowfield is difficult to reach and is uniformly distributed, and gas heat-transfer is insufficient, makes the chemical reaction of burning in a very narrow region
Inside carry out, so burn-out degree and pollutant discharge amount are higher.Additionally, naked light is big with external environment visibility, most of burning analysis
Heat causes effective heat transfer of the flame to the bottom of a pan with the air of convection type circumference and the wall with radiation mode circumference
Few, the thermal efficiency is low.
The burner of porous media was rapidly developed in the industrial production in recent years, and the burner of porous media has very
Many advantages, including less lean limit, higher burn rate and combustion stability, Flame Temperature Distribution is uniform, combustion
Gas burning is complete, and NOx, CO pollutant load produced after making burning greatly reduces, and these advantages meet current energy-saving and emission-reduction very much
State basic policy, a kind of therefore energy saving civil gas burning pot stove of necessary exploitation.
The content of the invention
The invention aims to overcome the ignition temperature skewness that existing domestic gas pot and stove is present, heating effect
Rate is low, and combustion intensity is little, the problems such as pollutant emission is high, and provides a kind of flames of anger gas-fired boiler of porous media radiant heating
Stove, and big, the safe and reliable energy-saving domestic gas pot and stove of combustion intensity.
For achieving the above object, the present invention is adopted the technical scheme that：A kind of energy saving civil gas burning pot stove is provided, at least
Comprising the kitchen range top, pan bracket, pot and burner, pan bracket is arranged on the kitchen range top of gas burning pot stove, the shell groove inwall of burner and shell
The space that the base plate of groove is surrounded from top to bottom be disposed with cystose honeycomb ceramic plate, heat-resisting steel bracket, top layer air distribution plate, in
Interbed air distribution plate, bottom air distribution plate and support column, are provided with heat resisting steel between cystose honeycomb ceramic plate and top layer air distribution plate
Support, top layer air distribution plate are seated on the welding groove of shell groove inner chamber by the fire resisting pad of refractory fibre matter；Intermediate layer air distribution plate
It is seated on the boss of shell groove inner chamber by the fire resisting pad of refractory fibre matter；Spiral shell is passed through by support column above the base plate of shell groove
Nail, plain washer and spring shim are provided with bottom air distribution plate, and gaseous mixture air inlet pipe is provided with below the base plate of shell groove；
Refractory fiber floor is provided between the shell groove inwall and cystose honeycomb ceramic plate of described burner；
Described burner premixes gas radiant heating type entirely for porous media, and burner uses unordered hole cystose honeycomb
Ceramic wafer, material are the cystose honeycomb ceramic plate of carborundum and alumina mixture；
Unordered hole cystose honeycomb ceramic plate ppi apertures used in described burner are 15～40；
The described kitchen range top is connected with shell groove, and reflecting plate is additionally provided with the kitchen range top, and reflecting plate one end is welded at the top of shell groove, the other end
Be welded on the inside of pan bracket, reflecting plate for by burner radiate and pot outer bottom radiation heat reflex to a pot outer bottom；
Described pot scribbles coating comprehensively for outer bottom band coating pot, i.e. pot outer bottom.
Combustion gas in described burner is first passed through with air and enter shell groove inner chamber from gaseous mixture air inlet pipe after tee T mixes,
Mixed gas after mixing are made pottery in the cystose honeycomb of porous after bottom air distribution plate, intermediate layer air distribution plate and top layer air distribution plate
Inside porcelain plate and surface combustion.
Described reflecting plate makes the tubaeform of upward opening using stainless sheet steel or copper sheet, reflecting plate and the kitchen range top into
45 degree of angles.
The coating of the pot outer bottom of described outer bottom band coating pot is perovskite or spinelle or a kind of coating in carborundum.
The burner of the present invention employs cystose honeycomb ceramic plate, heat-resisting steel bracket, top layer air distribution plate, intermediate layer cloth wind
The component such as plate and bottom air distribution plate, in order to ensure efficient burner, energy-conservation and reduce the discharge capacity of pollutant.In shell groove
The heat that interior fully pre-mixing gas combustion burning is produced passes to the external world by cystose honeycomb ceramic plate, between cystose honeycomb ceramic plate plate
Small spaces can ensure that the safety of comprehensive burning, heat transfer and the burner of combustion gas well.Combustion in the present invention
Burner is a kind of full premixed gas fuel burner of high performance, energy-saving porous foam ceramic plate, and this kind of burner makes
The burn-off rate and the thermal efficiency of combustion gas are significantly improved with the gas burning pot stove for enabling the present invention, while reducing the discharge capacity of pollutant.
The ppi of heretofore described cystose honeycomb ceramic plate refers to aperture.
Using a kind of material in perovskite or spinelle or carborundum as the pot outer bottom of outer bottom band coating pot in the present invention
Coating, is because that this kind of coating has larger blackness and resistance to elevated temperatures, more efficiently to absorb porous media radiation
Heat and the heat of baffle reflection that the burner of heating is produced.
The energy saving civil gas burning pot stove of the present invention is this have the advantage that compared with existing gas burning pot stove：
