Embodiment Construction

[0017] See figure 2 , the present invention includes a hopper 1 and a slag outlet 2, which also includes a first-stage fire grate 3 and a second-stage fire grate 4 arranged in a horizontal stack, and the feeding end of the second-stage fire grate 4 is located at the first-stage fire grate 3 Below the discharge end. The falling hopper 1 is installed at the feeding end of the first-stage fire grate 3; the slag outlet 2 is arranged at the end of the second-stage fire grate 4 in the feeding direction.

[0018] See image 3 , the first-level fire grate 3 and the second-level fire grate 4 can also be arranged in a parallel stacked manner obliquely downward, and the angle α between the first-level fire grate 3 and the second-level fire grate 4 and the horizontal direction is 15° ~20°, the two-stage fire grate adopts an oblique downward parallel stacking structure, which can further improve the disturbance of the coal in the furnace, so that the burned and unburned coal can be furt...

Abstract

The invention provides a double-chain fire grate structure of a coal-fired boiler. The problem that a double-chain fire grate structure of a conventional coal-fired boiler is poor in coal type adapbility can be solved, and the problem that a chain fire grate of a large-sized coal-fired boiler can be only assembled in a site can be solved. The double-chain fire grate structure comprises a blanking hopper and a slag outlet and is characterized by comprising a first-stage fire grate and a second-stage fire grate which are parallelly arranged in a stacked mode, and the feeding end of the second-stage fire grate is located under the discharging end of the first-stage fire grate.

Description

technical field [0001] The technical field of the coal-fired boiler of the present invention is specifically the double chain grate structure of the coal-fired boiler. Background technique [0002] For the chain grate structure of conventional coal-fired boilers, see figure 1 , which is a single-body grate. Because there is no disturbance in the coal seam during the transportation of coal materials, it is difficult to burn the coal materials, and the adaptability of the coal types is poor; The chain grate of the boiler can only be assembled at the boiler installation and construction site after being transported in bulk. The on-site installation workload is large and the transportation cost is high. figure 1 Among them, 1 is the hopper and 2 is the slag outlet. Contents of the invention [0003] In view of the above problems, the present invention provides a double chain grate structure for coal-fired boilers, which can solve the problem of poor adaptability of coal type...
