Abstract
What the present invention proposed is a kind of positive feedback fume-eliminating energy-saving combustion technology, it is that fuel with exterior combustion chamber burns, guide burner hearth into behind the high-temperature furnace gas heating inner combustion chamber of its generation, enter inner combustion chamber's burning again from the flue dust exit of burner hearth, enter chimney from the exit of inner combustion chamber at last and enter atmosphere.Adopt the present invention, flue dust can be carried out second-time burning, make it sufficient combustion, waste does not reach the effect of fume-eliminating energy-saving depositing dust.
Description
What the present invention proposed is a kind of new combustion technology-positive feedback fume-eliminating energy-saving combustion technology.
Prior art, as the circulating combustion technology, it is the high-temperature furnace gas that will burn, and the furnace gas of wherein 20-30% is turned back to the combustion chamber and newly enter the combustion chamber to prepare to participate in and burn after the air of burning mixes.The high-temperature furnace gas of 80-70% remains by chimney and enters atmosphere.Eliminate smoke, energy-conservation effect is undesirable.
The objective of the invention is to the problem at above-mentioned existence, propose a kind of positive feedback fume-eliminating energy-saving combustion technology, it can reach desirable smoke eliminating energy-saving effect.
Technical solution of the present invention: be that fuel with exterior combustion chamber 2 burns, the high-temperature furnace gas of its generation is used for heating inner combustion chamber 4, guide the burner hearth 5 that is used for the technology purpose then into, enter inner combustion chamber 4 from the flue dust exit 6 of burner hearth by the flue dust import 3 of inner combustion chamber 4 again and fully burn, enter chimney from the exit 8 of inner combustion chamber at last and enter atmosphere.
The left and right figure of accompanying drawing is respectively side-looking, the front elevational schematic of the present invention in combustion process.
Among the figure 1 is fire grate, the 2nd, exterior combustion chamber, the 3rd, inner combustion chamber's flue dust import, the 4th, inner combustion chamber, the 5th, burner hearth, the 6th, burner hearth place flue dust outlet, the 7th, body of heater, the 8th, inner combustion chamber's exhanst gas outlet.
The basic structure of using boiler of the present invention, stove cellar for storing things is: the combustion chamber is divided into inside and outside two combustion chambers and overlaps at a place, fuel combustion outer chamber burning also is blown into wind, secondary wind, and the high-temperature furnace gas of generation (containing black smoke and grit) is guided burner hearth into and is used for the technology purpose.Passage in the furnace wall enters the inner combustion chamber then, and feed combustion air simultaneously, and making flue dust fully burning in the inner combustion chamber, the heat of generation feeds back to exterior combustion chamber through its wall, make exterior combustion chamber maintain enough high temperature, help primary combustion and second-time burning.The flue gas that comes out from the inner combustion chamber is fully burned, is introduced into another passage in the body of heater.Enter chimney by the outlet flue on the body of heater after waste heat passed to body of heater.
Because the distance that flue dust is flowed through in body of heater is long, with the heat transferred body of heater, fallen and returned body of heater after warm flue gas enters inner combustion chamber's burning, after the heat transfer cooling, enter chimney by the body of heater outlet flue, make flue dust obtain abundant burning and sedimentation, and heat has obtained utilization, reduce heat loss due to exhaust gas, thermal pollution again, reached the effect of smoke elimination, energy-conservation, depositing dust.
Claims (1)
1, positive feedback fume-eliminating energy-saving combustion technology, it is characterized in that the fuel of exterior combustion chamber 2 is burnt, the high-temperature furnace gas of its generation is used for heating inner combustion chamber 4, guide the burner hearth 5 that is used for the technology purpose then into, enter inner combustion chamber 4 from the flue dust exit 6 of burner hearth by the flue dust import 3 of inner combustion chamber 4 again and fully burn, enter chimney from the exit 8 of inner combustion chamber at last and enter atmosphere.
