Problems solved by technology

When the coal is on the chain grate, it is easy to harden on the surface of the coal seam under high temperature conditions, which will block the ventilation and cause insufficient combustion, which directly affects the burnout of the fuel.
Even for some types of coal, due to the characteristics of the coal itself, the ash is loosely bonded after burning, and the ordinary chain grate cannot keep it burning

Embodiment Construction

[0014] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0015] like Figure 1~2 As shown, the present invention mainly comprises coal loosening support 5 and cooling water pipe 3, and described coal loosening support 5 is placed on the grate surface 4, and installation position is positioned between the 3rd air supply chamber 11 and the 4th air supply chamber 2; The loose coal support 5 is connected with the cooling water pipe 3, and the pipe body of the cooling water pipe 3 is fixed on the coal hopper of the chain grate or the front windshield door by the Ω type clamp 6. Described cooling water pipe 3 leaves a section of length on grate surface 4, makes loose coal support 4 not blocked by coal block.

[0016] like image 3 As shown, the loose coal support 5 includes an upper coal plate 7, a backing plate 8, a support frame 9 and a side sealing plate 10, the support frame 9 is an L-shaped plate, and the b...

Abstract

The invention relates to a coal loosening mechanism for a traveling grate stoker, in particular to a coal loosening device for a traveling grate stoker, which belongs to the technical field of traveling grate stokers of boilers. The coal loosening device is used for loosening a coal seam when coal passes through the traveling grate stoker, improving a ventilating environment of the coal seam and leading the coal to be combusted more sufficiently, and mainly comprises a coal loosening support and a cooling water pipe, and the coal loosening support is placed on a grate surface and mounted between a third air supply bin and a fourth air supply bin. The cooling water pipe is connected onto the coal loosening support, and a pipe body of the cooling water pipe is fixed onto a coal hopper or a front screen door of the chain grate stoker by a omega-shaped hoop. The coal loosening device is simple, compact and reasonable in structure, the hardened coal seam can be loosened, coal can be combusted more sufficiently, applicability to different types of coal is enhanced, the coal seam and loose and adhered ash generated after the coal is combusted are loosened, a combustion environment of the coal seam is enhanced, and the purpose of durable and stable combustion is achieved.

Description

technical field [0001] The invention relates to a coal loosening device for a chain grate. Specifically, when the coal passes through the chain grate, the coal seam is loosened, the ventilation environment of the coal seam is improved, and the coal is burned more fully, which belongs to the boiler chain grate technical field. Background technique [0002] In my country's small and medium capacity boilers, chain grate is widely used. The chain grate boiler adopts light chain grate to realize mechanical coal feeding, is equipped with blower and induced draft fan for mechanical ventilation, and is equipped with scraper type slag discharger to realize automatic slag discharge. The front and rear arches of the furnace adopt new energy-saving technology furnace arches. The fuel falls from the coal scuttle to the chain grate, and after entering the furnace for combustion, the flame is refracted upwards through the rear arch and then turned to the superheater and the tube bundle in...
