Description
Technical field
The present invention relates to a kind of energy conservation and environmental protection combustion gas with coil-shaped bilayer recuperator that Waste Heat Recovery utilizes
Stove, in particular to a kind of enclosed burning chamber, waste heat that high-temperature flue gas and heat radiation are isolated with room air in cookware heating
The energy-saving environment-protection gas-range of backheat, exhaust gas by emission by exhaust pipe to outdoor is carried out by coil-shaped bilayer recuperator,
Belong to gas combustion cooking utensil manufacturing field.
Technical background
Gas cooker common at present, is made of parts such as stove shell, stone or metal plate for standing a stove on as a precaution against fire burner, pan brackets.Combustion system is general
It is all the exposed open gas-cooker of stone or metal plate for standing a stove on as a precaution against fire, also referred to as air suspended type stove, in actual use, existing open gas cooker exists
There is following major defect:
The thermal efficiency of existing gas-cooker is lower, and heat loss is larger, and main cause is open burned flame heating cookware
When, flame envelope heated surrounding air simultaneously, without participate in pot body heating, flame thermal energy and radiation only some by the bottom of a pan
It absorbs, and temperature when flue gas leaves pot is also very high, a large amount of heat of this two parts is all due to no any heat recovery apparatus
It is all discharged into the indoor air environment of kitchen, causes great energy waste.
Various chemical pollutants caused by the open burning of existing gas cooker, such as carbon monoxide, oxynitrides
Equal toxic and harmful gas are all emitted in room air, are polluted to indoor environment, are endangered the health of user.
The high-temp waste gas discharged when the open burning of existing gas cooker, the thermal pollution generated in the room of kitchen, especially
It is that air environment is severe within summer, cooking environments backing hot, kitchen, endangers the health of user.
Summary of the invention
To solve the problems of above-mentioned open gas cooker, the purpose of the present invention is to provide one kind to add in cookware
High-temperature flue gas and heat radiation are isolated with room air when hot enclosed burning chamber, waste heat are by coil-shaped bilayer recuperator
Backheat, exhaust gas are carried out all by emission by exhaust pipe to outdoor energy-saving environment-protection gas-range.Stove thermal efficiency, big can be effectively improved
Width reduces energy dissipation, high-temp waste gas thermal pollution in the room of kitchen is effectively reduced, kitchen indoor environment exhaust gas chemistry dirt is effectively reduced
Contaminate the energy conservation and environmental protection gas-cooker of object.
A kind of technical solution of energy conservation and environmental protection gas-cooker with coil-shaped bilayer recuperator of the invention is as follows:
A kind of novel enclosed burning chamber that high-temperature flue gas is isolated with room air in cookware heating, waste heat are double-deck by coil-shaped
The energy-saving environment-protection gas-range of recuperator progress backheat.Including heat preservation combustion chamber, porous ceramic plate burner, igniting
