Description
The utility model relates to the chimney arch of boiler, particularly relates to the outer adjustable chimney arch of a kind of boiler body.
The Theory of Combustion of coal-burning boiler generally believes at present, the height of boiler thermal output, and size of exerting oneself and the adaptive capacity that operating mode is loaded except depending on coal-fired quality, are advanced outside the condition of air distribution, and the design of chimney arch also is one of important factor.The effect of chimney arch mainly is mixing and the guiding for the lighting of fire coal, heat radiation, flue gas flame, and keeps aspects such as burner hearth high temperature.So the reasonability of chimney arch design is vital for the thermal efficiency and the economy that improve boiler.The chimney arch of coal-burning boiler mainly is the shape and size that design chimney arch according to specific coal, so the chimney arch of boiler is fixed at present.When buying boiler, manufactory must use the coal of a certain particular range performance indications to the boiler of instruction manual different model like this.But because China's region broadness, coal is wide in variety, difference in quality is bigger.Thereby,, and cause the thermal efficiency of boiler low usually because the coal of buying does not reach the requirement of existing boiler to coal for the boiler of having purchased.Even some colms can't use at all and cause very big waste.If stop production for the variation that adapts to coal, carry out the transformation of chimney arch, generally be unlikely.
The purpose of this utility model is that design is a kind of can adapt to that coal changes and the operating mode load variations, and outside boiler body adjustable chimney arch.The face arch that is characterized in boiler comprises fixedly face arch and the preceding arch bar two parts of adjustable activity; Rear arch is made up of rear arch brick wall and adjustable movable back arch bar, arch bar and movable rear arch are firm and hard before movable now regulates flame angle, length, combustion conditions and radiation of control boiler hot and convection current by regulating, thereby also can light for colm, make various coals all combustible more abundant.When the operating mode load variations, also can reach desirable state by regulating, overcome the fixedly shortcoming of chimney arch of existing boiler.
The utility model is achieved in that the top of the fixedly face arch that turns forward at the burner hearth front end from bottom to top, a recessed dovetail groove is arranged along furnace width level side, have below the indent dovetail groove upper edge one adjustable outside boiler body, along perpendicular to arch bar before the upper and lower rotating activity of the horizontal axis of body of heater two sides.At burner hearth rear arch brick wall leading section, there is a boiler body outer adjustable, along perpendicular to the rotatable movable back of the horizontal axis of body of heater two sides arch bar.
Accompanying drawing has provided embodiment of the present utility model, is described further below in conjunction with accompanying drawing:

Traveling-grate stoker 1, coal bunker 2, coal gate 3, the coal lock is regulated sprocket wheel 4, fixedly face arch 5, boiler barrel 6, indent dovetail groove 7, indent dovetail groove upper edge 8, arch bar 9 before movable, movable back arch bar 10, rear arch brick wall 11, boiler jacket 12, " Qian " shape supporting base 13; rocking arm 14; handle 15; alignment pin 16; locating hole 17; fan-shaped adjustable plate 18; furnace wall heat-insulation layer 19; furnace wall brick 20; water screen tube 21; axis hole 22; rotating shaft 23; axle sleeve 24; high temperature protection cover 25; termination 26 of band square hole; square termination 27; collecting box pipe 28; steel skeleton 29; refractory material 30; hole, garden 31; garden shape adjustable plate 32; heart hole, garden 33; locating hole 34.
The length of arch bar (9) and movable back arch bar (10) is slightly less than the width of traveling-grate stoker (1) before movable, movable before after arch bar (9) and the activity width of arch bar (10) be furnace height 1/2～3/5 between.Its structure is the termination (26) that there is the band square hole both sides of steel skeleton (29), and steel skeleton (29) is gone up bag one deck refractory material.In the furnace wall of body of heater both sides heat-insulation layer (19), " Qian " shape supporting base (13) of four supporting shafts (23) is arranged, the axis hole (22) on each " Qian " shape supporting base (13).In the termination (26) of the band square hole of movable preceding arch bar (9), movable back arch bar (10), a rotating shaft (23) is respectively arranged, rotating shaft (23), on axle sleeve (24) is arranged, axle sleeve (24) is bearing in the axis hole (22) of " Qian " shape supporting base (13), and high temperature protection cover (25) is arranged outside the axle sleeve (24).The other end of rotating shaft (23) all stretches out outside the body of heater, the rotating shaft (23) of arch bar (9) is passed in the hole, garden (31) on the fan-shaped adjustable plate (18) on the boiler jacket (12) before movable, the rotating shaft (23) of movable back arch bar (10) is passed in the heart hole, garden (33) on the garden shape adjustable plate (32) on the boiler jacket (12), whenever the rotating shaft (23) of shaking is stretched to and is overlapped one on the external end respectively and shake wall (14); shaking on the other end of wall (14) has a handle (15); the leading section of handle (15) has an alignment pin (16); the alignment pin (16) that fan-shaped adjustable plate (18) is gone up on the corresponding handle (15) rotates on the camber line of garden; equally distributed locating hole (17) is arranged, and garden shape adjustable plate (32) is gone up on alignment pin (16) the rotation garden contour on the corresponding handle (15) equally distributed locating hole (34).
The utility model is to use like this, according to coal of using and boiler working condition load, just can realize regulating.When if the coal that uses is more inferior than standard-required, then need to make movable preceding arch bar, movable back arch bar is strengthened fire coal is carried out heat radiation, and flue gas and coal-fired heat convection.Therefore when adjusting, earlier rocking arm is outwards shifted out, the alignment pin just locating hole on fan-shaped adjustable plate and the garden shape adjustable plate is deviate from, and rocking arm is just rotatable, at this moment movable before arch bar, the just rotatable suitable angle of movable back arch bar.At this moment the close fixedly end of face arch of arch bar upwards lifts before movable, and movable back arch bar has rotated an angle near an end of rear arch brick wall.Thereby the resistance that makes gas-flow in the burner hearth be subjected to movable arch bar strengthened disturbance, strengthens the heat exchange to fire coal, even like this tinpot coal also light easily and burn abundant.If use standard compliant when coal-fired, movable before the position of arch bar adjust to and the fixing parallel position of face arch, movable back arch bar is adjusted to and the movable preceding parallel position of arch bar, thereby has reduced the resistance to gas-flow, and can play guide effect.When the boiler working condition load reduced, arch bar was horizontal level behind the adjustable, and coal-fired flame is reduced the radiation of boiler barrel, reached the purpose of control.
The utility model has the advantages that do not need the blow-on door outside body of heater just before the adjustable arch bar with movable after arch bar, not only reduce heat loss but also very convenient. Use boiler of the present utility model, no matter which kind of fire coal all can use, reduced the requirement to coal. Owing to make the abundant of fired coal combustion, alleviated the burden that the operator pokes fire, can improve the thermal efficiency 5～10% through using proof, and reduce the phosphorus content that coal is cut. The utility model can be used for the boiler manufacturing, also can transform existing boiler, all can produce good economic benefit and social benefit.
