Abstract

The invention discloses a boiler grate repairing method. The boiler grate repairing method comprises the following steps of a) disassembling grate fire bars and fire bar clamping plates to make gratechains exposed; b) measuring the consistency of the grate chains and measuring the parallelism between a front shaft and a rear shaft of the grate; c) disassembling, repairing and maintaining at leastone from the grate chains, the front shaft of the grate and the rear shaft of the grate; and d) assembling after repairing and maintaining so as to obtain the boiler grate after repairing and maintaining. The boiler grate repairing method provides a brand-new idea for repairing and maintaining the boiler grate, and provides a powerful reference to subsequent methods for repairing the boiler grate.

Description

Technical field [0001] The present invention relates to the technical field of boiler grate repair, in particular, to a boiler grate repair method. Background technique [0002] Chain grate is the most widely used mechanized combustion equipment in industrial boilers. The burning method of the chain grate is burning on a moving fire bed, and the burning condition is "limited fire". The fuel enters the grate through the hopper, and enters the furnace as the grate moves to start the combustion process. The burned-out slag is discharged to the slag well at the end of the grate along with the movement of the grate. [0003] After long-term use of chain grate, boiler grate pieces often fall off frequently. In severe cases, it will directly affect the stable operation of the boiler and the normal supply of steam, resulting in frequent shutdowns and repairs, and the frequency of repairs will vary with use As time increases, it becomes more and more frequent. [0004] Existing chain grate...
