The hot-air of combustion chamber upper end combustion-supporting hole sucking is also sucked down into combustion chamber lower part simultaneously, mixes with the carbon fire on sliding fire grate
Reach good burning condition, at this moment there is sufficient oxygen and combustible gas to add charcoal fire in the first crater of combustion chamber lower end
High temperature, makes its full combustion again, the heat to burn out through the recirculated water large area of each quirk water jacket fully absorb heat by
Outlet pipe enters caliduct and heats.The heat of chimney discharge is few, and chimney breast does not see cigarette, and not only heat utilization efficiency is high,
Fuel is saved, and reduces the discharge of flue dust.
The innovation of the multi-fuel energy-saving emission reduction stove for warming or cooking purpose is the design of lower crater, for those of ordinary skill in the art
For, in combustion chamber, each position can also set multiple lower craters.Expansion rising principle is heated according to air, the pulling through air-flow is
The lower crater burning of combustion chamber creates condition --- the combustible gas that 1. biomass heat resolves go out, 2. combustion-supporting holes sucking supplement
Into hot oxygen, the high temperature of 3. charcoal fire, the carbon in reasonable aerating distribution and furnace in combustible, combustible gas and lower crater
Fiery uniformly mixing full combustion, emission significantly reduce, and reach ideal high-efficiency low-emission.It is equipped with logical a heatable brick bed at logical a heatable brick bed mouth and leads to chimney turn
Change switch, heat can be passed through to warm a heatable brick bed, hearth is equipped with above combustion chamber, can heat up water cook, can with hot-water heating, again can heatable brick bed,
To realize multi-use, strength Natural Circulation, the thermal efficiency is high, temperature raising is fast, saves the energy, reduces pollutant emission.

When warming oneself with biomass fuel, light fuel wood in combustion chamber bottom surface, biomass briquette is filled it up with cover behind combustion chamber plus
Material lid, closes targeting port, the second crater and third crater, heated burning, and the biomass briquette on sliding fire grate is formed
Charcoal fire, the air expansion of heating, flows through chimney and rises, and drives the first crater of air-flow from the combustion chamber lower end in quirk horizontal
To air-breathing, the hot-air that the combustible gas and combustion-supporting hole for pulling the biomass briquette on combustion chamber top to be gone out by separating at high temperature suck is simultaneously
Into combustion chamber lower end, it is close to the burning of biomass charcoal fire and is flowed from the first crater to chimney direction；If using coal as fuel,
It is not necessary that coal is filled it up with fuel chambers, targeting port and the second crater are closed after covering feeding cover, opens third crater, the fire of burning
Flame enters in quirk from the third crater of combustion chamber upper end, enters chimney after the heat absorption of each quirk recirculated water large area and is discharged
It is outdoor.Heating system recirculated water enters furnace wall water jacket through water inlet pipe and carries out heating preheating, enters high-temperature region through recirculated water connection
Combustion chamber water jacket.Strong flame burns combustion chamber water jacket suddenly, and at this moment recirculated water reaches boiling point in the water jacket of combustion chamber, and high-temperature water is through going out
Water pipe rapidly flow toward heating system heat dissipation, the recirculated water of cooling flowed back to again through water inlet pipe completed in furnace recirculated water heating and
Heat dissipation.
When cooking, targeting port is opened wide, and the second crater and third crater simultaneously close off, and remove feeding cover.Combustion chamber is logical
It crosses feed opening to be connected with hearth, forms flame cavity between combustion chamber and hearth, flame is sought by combustion chamber from feed opening upwards
The pot pot etc. on hearth is heated out, later the quirk after flame cavity is entered by targeting port, enter back into chimney discharge.Also adjustable
It saves logical a heatable brick bed and leads to chimney change-over switch, into logical a heatable brick bed mouth heatable brick bed.
When logical a heatable brick bed, the second crater is opened wide, and third crater and targeting port simultaneously close off, and is adjusted the logical chimney of logical a heatable brick bed and turned
Switch is changed, logical a heatable brick bed mouth is opened wide, heat can be entered in a heatable brick bed by the second crater through logical a heatable brick bed mouth, realize quickly warm a heatable brick bed.If recalling to logical
A heatable brick bed leads to chimney change-over switch, leads to a heatable brick bed mouth and closes, and chimney opens wide, then air-flow enters chimney discharge.In addition, being equipped on the outside of the water jacket of furnace wall
Safety valve, this design be used in time in severe winter blowing out circulation in freeze, in order to prevent to light a fire raw furnace when furnace in generate pressure
It causes danger, safety valve pressure release can be opened.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
