Abstract
The utility model belongs to a kiln half gas combusting device. The utility model is characterized in that a grate is a moving grid, the upper surface and the lower surface of the grate is provided with a primary air pipe, the inner part of an ash pit is provided with a water sealing plate, the lower part of the ash pit is provided with water, the upper opening of the ash pit is provided with a cover plate, the outer side part of a kiln opening is provided with a hot air curtain, a fire path under a bocca is provided with a secondary air pipe, and the thickness of a coal layer is equal to 400-1500 mm. The utility model causes coal to be formed into mixed gas for being directly combusting, the utility model permits negative pressure operation, the temperature of a combustion chamber is high, the blackness of expelled smoke gas is low, and the utility model can reach international requirements. The utility model has the advantages of less investment, obvious effect and energy saving, and the utility model is an ideal combustion device for fireproofing material firing or metal heating kilns.
Description
The utility model relates to kiln, is a kind of pottery, refractory material burns till or METAL HEATING PROCESS kiln semi-coal gas burner.
At present, the pottery, refractory material burns till or METAL HEATING PROCESS coal firing stove kind is more, and tunnel cave, direct combustion kiln, down-draft kiln are arranged, kinds such as reflecting kiln, these kiln kind differences, but burn the burning of coal device substantially roughly the same, all be to constitute by ashcan, grate, fire door, furnace wall, bocca and coal seam, this burner coal combustion is insufficient, the discharging blackness of exhaustion is big during hand-stoked, and is most about Pyatyi, do not reach discharging standards, contaminated environment wastes energy.
The purpose of this utility model provides a kind of kiln semi-coal gas burner, and insufficient to solve existing coal firing stove burner coal combustion, the discharging blackness of exhaustion is big, does not reach discharging standards, contaminated environment, and problem such as waste energy.
The purpose of this utility model is achieved in that this burner is to be made of ashcan, grate, fire door, furnace wall, bocca and coal seam, grate employing activity grate, on grate or below be provided with airduct one time, in ashcan, be provided with water seal board, water is arranged at the bottom, suitable for reading have a cover plate, is provided with warm air curtain in the fire door outside portion, is provided with secondary air channel below bocca on the quirk.
Grate is tapered, reciprocating type, chain-type or be with grey hook grate;
Be with grey hook grate to adopt airduct to make, airduct vertically is provided with a row to last wind hole, and airduct is provided with control valve;
Be with grey hook grate to adopt real core fire bars to make, be provided with airduct one time below the grate, the airduct upper end is provided with blast cap, and control valve is arranged on the airduct;
Anthracite, low burnt matter layer bituminous lump coal or end are adopted in the coal seam, and its thickness is 400-1500mm;
Secondary air channel is provided with control valve.
This utility model compared with prior art has the following advantages: (1) coal generates mixed gas and directly burns, and sufficient combustion is saved the energy; (2) the semi-coal gas burning allows the negative pressure operation, and is safe and reliable than piped gas; (3) primary and secondary air adopts hot blast, helps improving ignition temperature, reduces the black smoke discharging; (4) fire door is provided with warm air curtain, and cold wind can blow burner hearth; (5) applicability is wide, is not only applicable to newly-built kiln, also is applicable to old kiln transformation, small investment, and instant effect, the discharging blackness of exhaustion is low, can reach discharging standards.
Be described further below in conjunction with accompanying drawing:
Fig. 1, kiln semi-coal gas burner structural representation
Among the figure: grate (3), burner hearth (5), bocca (6), furnace wall (7), fire door (10) and prior art are substantially roughly the same, grate (3) employing activity grate, movable grate is tapered, reciprocating type, chain-type or be with grey hook grate, taper, reciprocating type, the movable grate of chain-type is same as the prior art, be with grey hook grate, ash hook (2) intersects uniform with grate (3), ash hook (2) is by two guide supporting, by connecting rod, fork, handle drives, can be along the guide rail back and forth movement, make lime-ash miss discharge, be with grey hook grate (3) to adopt airduct to make, airduct vertically is provided with a row to last wind hole, perhaps grate (3) adopts real core fire bars to make, below grate, be provided with an airduct (1), airduct (1) upper end is provided with blast cap, airduct is provided with control valve, so that adjusting air quantity: in ashcan (14), be provided with water seal board (12), it is fixed or hangs over by screw on the furnace wall (7), and the ashcan bottom is marked with water (13), the lid (11) that is provided with suitable for reading, anthracite is adopted in coal seam (4), low burnt matter layer bituminous lump coal or end, coal seam thickness thickens, and is increased to 400-1500mm by original 300-400mm, is beneficial to coal-fired gasification; Be provided with warm air curtain (9) in fire door (10) outside portion, warm air curtain (9) is made up of pipe and hot blast, have at least one longitudinal joint on the pipe, the intrinsic baffle plate in seam both sides forms to guarantee warm air curtain, reduces cold wind and enters in the burner hearth (5) from fire door, below bocca (6) on the quirk, be provided with secondary air channel (8), secondary air channel is provided with control valve, can adjust combustion atmosphere.
Operation instruction: coal adds from fire door, elegance is made hot blast or need not an airduct (1) with air and water vapour, the hot water and steam gravity-flow ventilation that utilizes hot lime-ash to fall into the water and produce, after running into water vapour, fire coal can form mixed gas, coal gas and in burner hearth (5), form anoxic semi-coal gas burning from the oxygen that fire door is come in, fully burning after secondary air channel (8) oxygen supply, flame enters in the kiln from bocca, can be to pottery, refractory material burns till or metal is heated, on the kiln a plurality of semi-coal gas burners can be installed, concrete number will be decided according to the kiln design.
