Description
Technical field
The utility model relates to a kind of and coal-burning Industrial Boiler (except the station boiler), coal-burning industry heat-conducting oil furnace, coal-burning Heating Hot Water Boiler, coal-burning industry hot-blast stove, coal-burning industry calcining furnace, the chain type fire coal pressure combustion flame stove that the coal-burning Industrial Stoves are complementary.
Background technology
Existing all kinds of chain type fire coal industrial furnace, because of its technical pattern outmoded.Each manufacturer mostly is again follows imitation.Therefore, supply is machine-made negative-pressure firing form on the market.So the existing various industrial coal type of furnace often its real thermal efficiency is on the low side, the coal consumption height, flue dust, sulphuring treatment difficulty, the supporting efficient of subsidiary engine is big, and volume is big, and noise is big, and discharging exceeds standard, the pollution effect environment.
The utility model content
The technical problems to be solved in the utility model is: overcome the problem that prior art exists, design a kind of coal-burning traveling-grate stoker pressure combustion flame stove that traditional negative-pressure firing is pressure combustion, thermal efficiency height, sufficient combustion, energy-conserving and environment-protective that changes.
In order to deal with problems, the technical scheme that the utility model is taked is: this coal-burning traveling-grate stoker pressure combustion flame stove, comprise traveling-grate stoker, furnace wall, burner hearth, it is characterized in that: burner hearth comprises primary zone and secondary combustion chamber, traveling-grate stoker is installed in the furnace wall, the air feed mouth is established in the traveling-grate stoker below, chain fire-gate superjacent air space is the primary zone of burner hearth, the furnace wall top is provided with chimney arch, high temperature resistant Refractory blocks is installed near burner hearth one side in the chimney arch top, and the high temperature resistant Refractory blocks outside is a common refractory, the secondary combustion chamber of high temperature resistant Refractory blocks internal furnace, secondary combustion chamber is provided with the secondary air distribution mouth of pipe, and control of dust flame cap is installed on the flame fire door.
Control of dust flame cap is an arc, the last inclined screw bellmouth that is provided with at interval.
Flame fire door or be arranged on flame body of heater one side.Effect is to realize the side spray, matches with heated element such as horizontal boiler.
Operation principle
Changing traditional negative-pressure firing is pressure combustion.From taking the technical measures of strong air feed mouth below the horizontal line of conventional chains fire grate grate, make its protruding malleation fire coal that becomes.Above the horizon take measures from traditional chain fire-gate grate, make and assemble special-purpose furnace wall, chimney arch, secondary combustion chamber, the secondary air distribution mouth of pipe, the control of dust flame cap of band inclined screw bellmouth.With the combustion chamber that above-mentioned parts is formed, can control fuel and change from the process in burning initial stage-mid-term-latter stage, adjust the physics and chemistry mechanical incomplete combustion index of combustion process.Thereby realize the purpose of the utility model technology pursue.
Compare with the combustion chamber of existing traditional chain grate boiler, the beneficial effect that the utlity model has is:
Energy-conservation: changing traditional negative-pressure firing is pressure combustion, thermal efficiency height, flame is strong, energy-conservation reaching more than the 10-20%, environmental protection: sufficient combustion, after fuel enters chain from coal bunker, slowly successively by three Duan Feng districts, at three different formed flames in burning wind district, the indoor rapid mixing of burner hearth primary combustion in furnace wall formation, be admitted to secondary combustion chamber after colliding chimney arch, under the impact of secondary air distribution mouth of pipe air-supply, produce eddy current, circumvolution rises to side space under the control of dust flame cap that has the inclined screw bellmouth, and under rational pressure, clean-burning flame is by force by red-hot inclined screw bellmouth flame behind the realization control of dust, under the state that certain rigidity and length are arranged, spray in the heated element.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.It is most preferred embodiment of the present utility model.Wherein: 1 traveling-grate stoker, 2 furnace walls, 3 chimney arch, the 4 high temperature resistant Refractory blocks 5 secondary air distribution mouths of pipe 6 secondary combustion chambers 7 control of dust flame caps 8 inclined screw bellmouths 9 coal bunkers 10 air feed mouths.
The specific embodiment
As shown in Figure 1: this coal-burning traveling-grate stoker pressure combustion flame stove, comprise traveling-grate stoker, furnace wall, burner hearth, it is characterized in that: burner hearth comprises primary zone and secondary combustion chamber, traveling-grate stoker 1 is installed in the furnace wall 2, air feed mouth 10 is established in traveling-grate stoker 1 below, the superjacent air space of traveling-grate stoker 1 is the primary zone of burner hearth, furnace wall 2 tops are provided with chimney arch 3, high temperature resistant Refractory blocks 4 is installed near burner hearth one side in chimney arch 3 tops, high temperature resistant Refractory blocks 4 outsides are common refractory, in the high temperature resistant Refractory blocks 4 is the secondary combustion chamber 6 of burner hearth, secondary combustion chamber 6 is provided with the secondary air distribution mouth of pipe 5, control of dust flame cap 7 is an arc, is installed on the flame fire door, and a space is formed at bottom and secondary combustion chamber 6 tops.Inclined screw bellmouth 8 is set on the control of dust flame cap 7 at interval.
