Abstract
The invention discloses a universal method for manufacturing cooking furnace composed of a pre-heater for pre-heating air and fuel gas, a sealing annular hearth for reclaiming smoke gas, and a premix burner with the secondary air as zero, comprising: the fuel gas and air are mixed once according to the chemical equivalent for the burning to emit heat through the burning of the burner in the hearth and exchange heat with the furnace. An annular pot frame is tightly jointed with the pot not to cause the burnt and heat-exchanged smoke gas to escape, but to enter the pre-heater through a flue near a grate on the hearth, and to release and exhaust the sensible heat and latent heat out of the furnace after the secondary heat exchanging. The method integrally adopts the techniques of premix burning, waste heat recovery of air pre-heating to increase the heat exchange efficiency of the furnace greatly, and according to the different use requirements and places, the maximum heat efficiency of the furnace can reach over 100% of the low heat value to cause the smoke gas to be condensed and exhausted. A lot of fuels can be saved and the exhaust of the waste gases, such as carbon dioxide and carbon oxide, can be reduced, since the increased efficiency can greatly reduce the heat load of the furnace. The invention can be used for the household furnaces and all the cooking furnaces.
Description
Technical field
The present invention relates to a kind of preparation method of stove and accessory, is exactly to relate to a kind of cooking stove preparation method that has heat-exchange apparatus specifically.
Background technology
The most domestic burners that emerge at present and a part of commercial cooking stove generally all are the burnings of atmosphere injection type, need auxiliary air to replenish during burning.Be heated pot body and generally erected, make the outer air of stove to add in the stove at the steelframe place.Furnace bottom also communicates with atmosphere, and gas fume after burning is discharged into atmosphere at the grate place.Very most heat has scattered and disappeared in this open type burning, makes fire box temperature reduce unfavorable heat exchange.Because in open type burner hearth internal combustion, the residual heat high-temperature flue gas just is not discharged into atmosphere through utilizing, so the heat exchanger effectiveness of general domestic burners has only 50%-60%; Commercial stove is in order to increase effective power, and thermic load generally all surpasses 25,000 kilocalories, and effectively the exchange area increase is limited, so heat exchanger effectiveness is just lower, generally has only about 20%, and a large amount of valuable energy are wasted.Most stove and accessory carbon monoxide and oxynitrides and greenhouse gases greenhouse gases emission amount of carbon dioxide are also high simultaneously.
Summary of the invention
The present invention has overcome the defective of prior art, provides a kind of and can improve the stove and accessory heat exchanger effectiveness, can lower carbon monoxide again, the general stove and accessory preparation method of oxynitrides and CO2 emission concentration.
Technical scheme of the present invention is: in the airtight annular furnace premix burner is arranged, burner hearth outside has the have surplus heat outlet passageway of flue gas of air, gas preheater, annular furnace to link to each other with preheater, and its position is below the pot frame.Described airtight annular furnace is a bottom lock, the pot frame of top annular and be located lightly fried dumpling on it close form airtight.Described premix burner is that auxiliary air is zero burner.Described preheater is the heat exchanger of air, combustion gas and high-temperature residual heat.Described outlet passageway is evenly distributed on one week of burner hearth.Owing to adopted above technical scheme, the present invention, a kind of beneficial effect of preparation method of cooking stove is, both improved heat exchanger effectiveness, reduced the thermic load of stove and accessory again.The smog discharge temperature of stove and accessory is according to different demands, minimumly can be controlled to dew point, discharges after the condensation, can maximally utilise the sensible heat and the latent heat of flue gas.The carbon monoxide in the stove and accessory discharging waste gas and the concentration of oxynitrides are reduced greatly.The heat exchanger effectiveness of Domestic stove is the highest can to reach low-calorie more than 100%, promptly so-called condensing, and the concentration of emission of carbon monoxide and oxynitrides can be below 100ppm, and the preparation method of this stove and accessory is fit to be applied to all cooking stoves.
