Embodiment:

Its processing and fabricating of high-efficiency multi-function cooking heating furnace of the present utility model is very simple and convenient, installs shown in the by specification accompanying drawing to make to get final product.Below this high-efficiency multi-function cooking heating furnace distinguishing feature, function and using method are done following introduction:

Back-fire point stove: when the igniting of normal domestic use cooking heating furnace, be spunk to be put on grate, under grate, firewood is lighted, or earlier the waste paper of lighting is put in the stove tube, again firewood is put on the waste paper of burning, by the time again moulded coal is put into after firewood is lighted, stove is just lighted up to moulded coal burning back, the result of this mode of igniting is the igniting duration, igniting can not be covered bell again, institute is so that coal smoke emits indoor entirely, not only put the nasal mucus tears that the stove person choked and flow together, and seriously polluted environment.The igniting of this high-efficiency multi-function cooking heating furnace can be opened the down smoke-discharging door that control ash-falling chamber and smokejack in the ash-falling chamber open and close, then firewood is put into earlier on grate, light a fire from the firewood top with waste paper then, pyrotechnics is lighted firewood downwards under the attraction of smokejack, pyrotechnics enters ash-falling chamber, enter smokejack by exhaust opening, treat after firewood is lighted moulded coal directly to be put on the firewood of burning, cover bell, again the down smoke-discharging door in the ash-falling chamber is closed, open the smoke evacuation door simultaneously and allow down fire door and smokejack communicate, upwards burning of pyrotechnics at this moment, the dense smoke that firewood and coal mixed combustion produce is discharged from the stove nozzle, directly enters smokejack through last smoke evacuation door.Treating will go up after the coal completing combustion smoke evacuation door closes, the high temperature coal smoke that the stove tube is emerged divides two-way to enter shell and tube smoke exhaust pipe and the flue gas descending circular passage heat exchange in the furnace shell outside the water-jacket typ, be advanced into dust chamber under the flue gas after the cooling, flue dust enters smokejack again and discharges outdoor after dust chamber purifies, do not have cigarette ash in whole ignition process emits indoor for this reason, this operating process also can be used for changing moulded coal, end pot, the operation when changing the kettle ash disposal, the just upward switching of down smoke-discharging door of control of its operation, very simple and convenient effective.Heated on the two sides of furnace shell and the descending circular passage of flue gas in the cold air that enters secondary wind preheating channel from secondary wind air intake passage was subjected to secondary wind preheating channel, the stove nozzle is emerged contains unburnt carbon monoxide high-temperature flue gas and mixes above the preheating of secondary wind is logical and through the air of the logical two road preheatings of secondary wind preheating and carry out secondary and fully burn, and then divide two-way to enter smoke exhaust pipe and the descending circular passage of flue gas in the outer furnace shell of water-jacket typ respectively, after the dust chamber udst separation of furnace shell bottom, enter smokejack again and discharge in flue gas after the heat exchange cooling all is advanced into down simultaneously.Therefore coal is in the high-temp combustion state all the time in the stove tube, so efficiency of combustion is than high many of existing various domestic heating cooking stove.

Thermal efficiency height: because this stove and accessory has adopted outer furnace shell of the tubulation water-jacket typ of big heat exchange area and the two heat-exchanger rigs of bell formula heat exchanger, with secondary air burning design, so can in maximum magnitude, reduce energy loss, the heat that coal burning produced is all used, what coal burnt uses up, it is complete that heat is used, to reach the higher thermal efficiency.

High burning performance: adopt twin furnace shell furnace binding, heat-exchanger rig is designed on clean-burning basis under the coal high temperature, so in the stove tube of coal in interior furnace shell with the ignition temperature burning of high the best, the carbon monoxide that burns incompletely carries out real second-time burning with heating back hot-air on two air intake preheating channel mouths, but also in the design of stove tube middle part,, coal provides the secondary of sufficient hot-air wind micropore air intake passage for fully burning, so burning of coal efficient can be brought up to maximum, the content of the carbon monoxide in the flue gas is reduced to bottom line.The effect in the natural air inlet hole of secondary wind preheating channel bottom is that the slow fire second-time burning for coal does not provide necessary air when stove and accessory does not need very hot oven that secondary wind air intake passage is closed.

Sanitation performance is good: in order to solve existing stove and accessory point stove; the seat pot is sat kettle and is changed coal; the problem of cigarette ash serious environment pollution during ash disposal; adopted the retrograde heat-exchange dedusting design of cigarette ash on the stove and accessory of the present utility model; flue gas in the stove tube is not emerged from last fire door during igniting and when changing coal; but the dust chamber of passing through under the tubulation smoke exhaust pipe in the furnace shell and the descending circular passage of flue gas outside water-jacket typ enters smokejack again; the cigarette ash of stove and accessory when normal combustion also be earlier outside water-jacket typ tubulation smoke exhaust pipe heat exchange in the furnace shell and the descending circular passage of flue gas go downwards to dust chamber; flue gas after being purified enters outdoor again from smokejack; so can not only protect indoor environmental sanitation, also protect the Nature not to be subjected to the pollution of flue dust simultaneously.

High-efficiency multi-function cooking heating furnace of the present utility model is compared with existing technology, Have reasonable in design, simple in structure, clean hygiene, energy savings, thermal efficiency height, The characteristics such as easy to use, thereby, be the substitute products of existing stove and accessory, will have very Good extension use value.

Except the described technical characterictic of specification, be those skilled in the art Know technology.
