Abstract
The utility model relates to a coal gasification ordinary pressure burning furnace, which aims at solving the technical problem that direct fired burning furnaces can not generate dry distillation gas. The upper central part of a vertical drum(1) is connected with a chimney(1-5) with an internal furnace(3). The vertical drum is connected with a double E-shaped baffle wall(2) to an inclined arc baffle wall(5) on the lower part of the vertical drum. The vertical drum forms a coal bunker with the internal furnace(3). The upper part of a coal feed gate(4) is eccentrically connected with the internal furnace. A flue gas hole(6) is arranged on the arc baffle wall(5). The arc baffle wall(5) communicates with the a spiral passage of the baffle wall(2). A slag remove gate(7) of the lower coal feed gate communicates with the arc baffle wall(5). The utility model has advantages of scientific design, thrift on energy resource and high heat efficiency. The utility model is applicable to heating of living rooms and baths, as well as domestic water.
Description
The utility model belongs to the normal pressure combustion furnace, and particularly a kind of burning solid is coal-fired and produce the coal gasification normal pressure combustion furnace of coal gas.
At present, the heat heating boiler inner furnace that combustion furnace buring solid fuel coal discharges produces heat, and to the aqueous medium heating, inner furnace is direct-fired, heating surface area is little, can not produce coal gasification, fuel gas is not fully burning in the stove hall, and fuel gas is directly discharged from inner furnace to combustion chamber chimney, produce the black flue dust, contaminated environment, waste fuel, the thermal efficiency only reaches 40 percent.
The purpose of this utility model is to overcome above technical deficiency, and the coal gasification normal pressure combustion furnace of a kind of thermal efficiency height, sufficient combustion is provided.
For realizing above purpose, technical solutions of the utility model are to realize like this, coal gasification normal pressure combustion furnace, having has top, inner furnace fixed grate side to have air regulation coal feeding door bottom in vertical drum inside to have the air regulation shoot door by the drop-bottom back cover, upper end central part and the inner furnace chimney that joins in the vertical drum, under connect two " E " type smoke bending plates to coal gas inclined smoke bending arch plate and inner furnace composition coal bunker, at air regulation coal feeding door top and the inner furnace off-centre coal gas inclined smoke bending arch plate that joins, have smoke hole on the coal gas inclined smoke bending arch plate of bottom and communicate with smoke bending plate " E " type spiral flue, the clean-out door of bottom communicates with the coal gas inclined smoke bending arch plate.
The coal gas inclined smoke bending arch plate top that is connected with inner furnace off-centre is folding cigarette hang plate, and the smoke bending plate that top joins is with vertical drum upper end central part chimney off-centre, and two " E " type flues of coal gas inclined smoke bending arch plate are helical structure.
Coal gasification normal pressure combustion furnace is in vertical drum, form coal bunker by coal gas inclined smoke bending arch plate and inner furnace, off-centre at the coal gas inclined smoke bending arch plate is joined, draft by chimney makes and produces negative pressure in the burner hearth, the flue gas that produces in the coal bunker enters the combustion chamber by the smoke hole adverse current, but burning fume fully burns smoke abatement and dust control by the spiral flue of " E " type smoke bending plate.
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 shows coal gasification normal pressure combustion furnace profile.
The A-A profile of Fig. 2 diagrammatic sketch 1.
The C of Fig. 3 diagrammatic sketch 1 is to view.
The B-B cutaway view of Fig. 4 diagrammatic sketch 3.
Among the figure, the vertical drum of 1-; 1-1 water level meter, 1-2 atmospheric communicating pipe, 1-3 thermometer, 1-4 Pressure gauge, 1-5 chimney, 1-6 outlet pipe, 1-7 look fire hole, 1-8 return pipe; 1; The 2-smoke bending plate; The 3-inner furnace; 4-air regulation coal feeding door; 5-coal gas inclined smoke bending arch plate; The 6-smoke hole; The 7-clean-out door; 8-air regulation shoot door; The 9-drop-bottom; 10-is grate furnace fixedly
With reference to accompanying drawing 1-4, coal gasification normal pressure combustion furnace, have in vertical drum (1) inside inner furnace (3) is arranged, fixed grate (10), top, side has air regulation coal feeding door (4), the bottom has air regulation shoot door (8), by drop-bottom (9) back cover, upper end central part and inner furnace (3) chimney (1-5) that joins in the vertical drum (1), under connect two " E " type smoke bending plates (2) to coal gas inclined smoke bending arch plate (5) and inner furnace (3) and form coal bunker, at air regulation coal feeding door (4) top and inner furnace (3) the off-centre inclined smoke bending arch plate (5) that joins, have smoke hole (6) on the bottom smoke bending arch plate (5) and communicate with smoke bending plate (2) " E " type spiral flue, the clean-out door of bottom (7) communicates with coal gas inclined smoke bending arch plate (5).
Coal gas inclined smoke bending arch plate (5) top that is connected with inner furnace (3) off-centre is folding cigarette hang plate, and the smoke bending plate that the bottom joins (2) is with vertical drum (1) upper end central part chimney (1-5) off-centre.Two " E " type flues of coal gas inclined smoke bending arch plate (5) are helical structure.
With reference to accompanying drawing 3, for the C of coal gasification normal pressure combustion furnace air regulation coal feeding door 4, air regulation shoot door 8 to view.
Use coal gasification normal pressure combustion furnace, method of operating: on fire grate, place seasoned wood or the igniting of wooden carbon, add coal cinder by air regulation coal feeding door 4 then, fill it up with coal bunker after the bunker coal burning, regulate air regulation coal feeding door 4 and air regulation shoot door 8 and make air enter burner hearth respectively, sight is looked into and is looked fire hole 1-7 combustion case, damper 4-8 makes fuel gas detonation in the burner hearth, normal combustion, chimney 1-5 cannot see flue dust, and is as clear as crystal.
Coal gasification normal pressure combustion furnace, in burner hearth, form coal bunker by coal gas inclined smoke bending arch plate 5, draft by chimney 1-5 makes burner hearth produce negative pressure, produce flue gas in the coal bunker by the smoke hole adverse current, enter in the combustion chamber, but make burning fume gas detonation in burner hearth, flue gas fully burns, grit is fallen by smoke bending plate 2 bumps, and is energy-efficient, do not need power supply.Its operation principle, utilize stack draught, make and produce negative pressure in the burner hearth, make coal carry out oxidation reaction and form dry distillation gas fully burning in burner hearth, temperature can reach 1.100-1.300 ℃, effectively utilize the coal tar after-flame that the physics heat energy of fuel is produced, smoke abatement and dust control voluntarily, fuel savings is more than 50%.Meet the national environmental protection index after tested, flue dust average emission concentration C 35.8mg/m
3, conversion smoke dust discharge concentration Ca76.0mg/Nm
