Abstract
The utility model relates to a minitype domestic multi-purpose stove for cooking and heating. The purpose of the utility model is to provide a secondary air multi-purpose stove for cooking and heating, which adopts structures of secondary air and vertical two-stroke heat exchange flues. The utility model has the advantages of reasonable and sufficient combustion and heat exchange, smoke prevention, dust control and capability of achieving good integral effects of energy saving and environmental protection. Bituminous coal, or anthracite, or briquette can be burnt in the utility model. Due to the reasonable allocation of the secondary air, the operation is simple, and the utility model can burn completely and sufficiently with heat efficiency reaching more than 70 percent. The utility model has good effects of smoke prevention and dust control and can meet the requirements for discharge and blackness of smoke and dust in the first class region, which are prescribed in GB13271-2001 'standard for discharge of pollutants of boiler atmospheric air'.
Description
The utility model relates to household small-size cooking, heating stove.
At present, domestic vast town and country number mostly is raw coal in necessarily family's cooking, heating stove and directly burns at burner hearth, and the thermal efficiency is very low, only is about 50%; And the fugitive constituent in the fire coal because burner hearth throat temperature is low, to discharge fume residence time extremely weak point can not fully burn, form soot and dust and be discharged into atmosphere very soon, not only form unnecessary heat loss, and environment caused severe contamination.Now, environmental protection has become the public's strong desire, limit smoke emission request increasingly stringent.Prior art is to eliminate the black smoke and the raising thermal efficiency that directly burning produces, and the measure that increases secondary wind is also arranged, though effect is better, but complex structure, cost of manufacture is very high; What have is simple in structure, but result of use is poor.For the energy resource structure of the vast town and country of China based on fire coal, adopt the structure of renewal and the energy that combustion method improves the thermal efficiency, saves valuable, and make great efforts to reduce domestic life stove and accessory Air Pollutant Emission, protection environment, be of great immediate significance.
The purpose of this utility model is to propose the cooking of a kind of secondary wind, heating stove, this kind boiler adopts and at furnace outlet secondary wind is set, make burning more abundant, vertical two return heat exchange flue is set thereafter, make heat transfer, heat exchange more reasonable, has the effect that is beneficial to the flue dust sedimentation simultaneously, to reach the good result of energy-saving and environmental protection.
The solution that the utility model provides is that the body of this boiler is a square structure, and the front portion is a hearth water sleeve, and the rear portion is vertical two return heat exchange flue.Arrange secondary air channel in the burner hearth flame retardant coating, lead to burner hearth top throat; The bottom is provided with drop grate; Be the ash bucket of sealing under the drop grate, the ash bucket front panel is equipped with regulates the primary and secondary air aerofoil.Burner hearth throat top is basin shape fire chamber, enters the vertical two return heat exchange flue of being made up of three road water jackets through the square trunnion of rear side, and bending upwards is a Pipe saddle for chimney through " U " type.Burner hearth is connected by body of heater both sides water jacket with the water jacket of two return heat exchange flue; The above and below that supply, the backwater base is arranged on rear side; The water jacket highest point is equipped with the air vent seat of straight-through atmosphere.
Accompanying drawing is the embodiment body construction schematic diagram of the cooking of a kind of secondary wind, heating stove.
In the present embodiment, the cooking of a kind of secondary wind, heating multipurpose boiler body are square structure, apply refractory insulating layer 3 around the burner hearth 1, and secondary air channel 2 is buried underground wherein, and wind tube outlet is positioned under the burner hearth throat 8; Water jacket 4 tops in front side have firing door 5; Being basin type fire chamber 6 on the throat, is the cast iron flat 7 that the stove circle is housed on it; " U " type flue that fire chamber rear side is made up of square trunnion 9 and curved water jacket 13, downward-flow flue 14, uptake flue 15 communicates, flue bottom installing shoot door 16; The flue upper outlet is a Pipe saddle for chimney 10, and what base was coiled in the Pipe saddle for chimney bottom in water jacket is one group of water-water-to-water heat exchanger 11; Burner hearth below is that 18,2～3 drop grates of drop grate can stretch out the connecting rod of installing on the axle head by a side and shake; Push-and-pull ash bucket 19 is housed under the fire grate, and the ash bucket front panel is equipped with regulates primary and secondary air aerofoil 20.Water supply base 12 is arranged at rear side water jacket top, and backwater base 17 is arranged at rear side water jacket bottom.
Now in conjunction with the accompanying drawings the utility model is further elaborated:
Behind the coal of igniting on the fire grate, the ash bucket push-and-pull promptly is to adjust primary and secondary air synchronously, the flame that the calculating of secondary air channel flow area and resistance produces fired coal combustion can be equipped with an amount of secondary wind in burner hearth throat, make flame reach maximum temperature entering basin shape fire chamber, the fugitive constituent of separating out is abundant after-flame also.Coal-fired half effect that gasifies is used to cook, heat up water.Flue gas enters downward-flow flue through square trunnion, in relatively large convection heating surface heat transfer, heat exchange with certain speed, the grit of carrying under one's arms sedimentation in subsequently dilatation, deceleration, steering procedure, curved water jacket under the Pipe saddle for chimney also can not cause dust accretions, and cleaning flue gases upwards drains into atmosphere by chimney.Along with the carrying out of burning, dust stratification thickening on the fire grate, this moment, shaking grate can drain into ash the bottom ash bucket gently, regularly went out clearly.When not needing very hot oven, ash bucket can be advanced, insulation situation is optionally stirred aerofoil, regulates first and second intake, the control combustion position; When banking up a fire, Close All.Fuel adds with combustion position as required from firing door, neither influences cooking, the indoor pollution in the time of can eliminating coal again.
Water circulation system is the heating backwater by the input of backwater base, owing to be subjected to heat effect to continue to be risen on the top by the bottom, the pipeline that is connected by the water supply base on top when water temperature is the highest is exported to heating system.Life is to connect running water at water-water-to-water heat exchanger inlet with hot water, and outlet can connect boiler or shower.
Can install insulation material, foreskin outside the body, have the good surface appearance moulding, in energy savings, protection environment, promote the quality of life of vast urban and rural residents.
The utility model fuel tolerance is wide, and burning bituminous coal, anthracite also can be adjusted the method for operating burning briquette.
The utility model makes burning fully, fully because the suitable adapted of secondary wind and two return flue is easy and simple to handle, and the thermal efficiency can reach more than 70%; Smoke medicining dust-removing effect is better, and the inspection body of authorized by state is detected, and satisfies the class one zone soot emissions requirement of GB13271-2001 " emission standard of air pollutants for boilers " regulation.
