Slag discharging system applicable to power station boiler

Abstract

The invention discloses a slag discharging system applicable to a power station boiler. The slag discharging system comprises a steel belt conveyor; a hollow strip-shaped trough capable of swaying back and forth in the slag output direction is arranged at the bottom of the output end of the steel belt conveyor; multiple parallel steel rollers are fixed to the bottom of the hollow strip-shaped trough; the input end of the hollow strip-shaped trough is higher than the output end; a conveying belt is arranged at the bottom of the output end of the hollow strip-shaped trough; a slag bucket a is arranged at the bottom of the output end of the conveying belt; a slag crushing machine is arranged at the bottom of the hollow strip-shaped trough; and a slag bucket b is arranged at the bottom of theoutput end of the slag crushing machine. With the adoption of the slag discharging system applicable to the power station boiler, large coke blocks in slag can be filtered out before the slag enters the slag crushing machine, jamming tripping of the slag crushing machine due to the large coke blocks is avoided, and thus the operation reliability of the unit is improved.

Description

technical field [0001] The invention belongs to the technical field of slag discharge for pulverized coal boilers, and relates to a slag discharge system suitable for power plant boilers. Background technique [0002] For a long time, my country's thermal power plants have generally had the problem of boiler coking, and with the continuous decline of coal quality, the problem of coking has become more prominent. For the air-cooled dry slag removal system, a large amount of slag will not only cause insufficient output of the steel belt machine, but also large pieces of slag will cause jamming and tripping of the slag crusher. The service life of the generator will also be drastically reduced, increasing the cost input of thermal power generation. The slag crusher jams and trips, and cannot resume operation for a long time, which will cause non-stop of the unit and seriously affect the power generation efficiency. Contents of the invention [0003] The purpose of the prese...

Problems solved by technology

For the air-cooled dry slag removal system, a large amount of slag will not only cause insufficient output of the steel belt machine, but also large pieces of slag will cause jamming and tripping of the slag crusher. The service life of the machine will also be reduced sharply, increasing the cost input of thermal power generation

The slag crusher is stuck and tripped, and cannot resume operation for a long time, which will cause non-stop of the unit and seriously affect the power generation efficiency
