Abstract
The utility model relates to a chain type shaped coal boiler. A chain type shaped fire grate (1) is arranged at the lower part of a furnace (12), a coal inlet (2) is arranged in front of the fire grate, an ash outlet is arranged at the rear part of the fire grate, and a hot water changing pipe (3) and / or a water tank (4) are arranged in the furnace. The utility model is characterized in that the upper part of the middle section of the fire grate is provided with a middle arch (8) which is inclined backwards. The utility model can improve the combustion condition of honeycomb coal in a chain boiler with large power in order to combust honeycomb coal fully, and the heat efficiency of the chain type shaped coal boiler is increased.
Description
Technical field
The utility model belongs to a kind of chain type boiler of briquet.
Background technology
Chain type boiler is provided with chimney arch usually above the chain furnace grate of burner hearth, the chimney arch that is located near the coal feed point position is preceding chimney arch, chimney arch near the ash hole position is the back chimney arch, space between the forward and backward chimney arch is a burner, the effect one of chimney arch is to burn red chimney arch can work the effect of lighting to the coal on the fire grate, the 2nd, block flare from the top, flare is pressed to the burner direction.During this burning in boiler honeycomb briquet and since honeycomb briquet band itself vertically to air vent, when its top has chimney arch to stop, influence combustion efficiency, have burn not to the utmost problem of moulded coal.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of chain-type molded coal boiler that burns honeycomb briquet that is applicable to.
The technical scheme that addresses the above problem is (referring to implementing illustration): the utility model is provided with chain furnace grate (1) in burner hearth (12) bottom, the front portion of fire grate is provided with coal feed point (2), the rear portion is provided with ash hole (11), be provided with heat exchanging water pipe (3) and/or water tank (4) in the burner hearth, it is characterized in that: described fire grate (1) is leading portion (A) near the position of coal feed point, position near ash hole is back segment (C), position between the front and rear sections is stage casing (B), the top of fire grate stage casing (B) be provided with sweptback in chimney arch (8).
The leading portion of the utility model chain furnace grate is a preheating section, and the stage casing is the section of lighting, and back segment is the after-flame section, when honeycomb briquet enters the fire grate leading portion from coal feed point, be preheated earlier, when entering the stage casing, being burnt red middle chimney arch (8) by the top lights, the middle chimney arch that the while flare is tilted is guided leading portion into, and the moulded coal on the heating leading portion fire grate is when entering back segment, because the top is not provided with chimney arch, reduced the up resistance of flue gas, honeycomb briquet is fully burnt, discharged from ash hole then.
The utility model can improve the combustion position of honeycomb briquet in high-power chain-grate boiler greatly, makes honeycomb briquet be able to abundant burning, improves the thermal efficiency of chain-type molded coal boiler.
