受热面的磨损泄漏是烧煤锅炉引起临时检修的主要原因之一,而省煤器又是锅炉受热面最薄弱环节。我厂在1978～1979年中由于省煤器磨损而被迫停炉检修共12次,占厂受压部件故障的30～50%,不仅影响工农业用电,而且还要多耗煤。因此,对于已经建成的电站锅炉,在不能改变其结构的条件下,积极地采取预防措施,大幅度地降低由于飞灰磨损而引起的停炉故障,是有其重大意义的。近两年来,我厂在省煤器防磨方面做了一点工作,并取得
The wear and tear of the heated surface is one of the main reasons for temporary maintenance of coal-fired boilers, and the economizer is the weakest link in the heating surface of the boiler. I plant in 1978 ~ 1979 due to economizer wear and tear was forced to shut down overhaul a total of 12 times, accounting for 30 ~ 50% of the affected parts failure, not only affect the industrial and agricultural electricity, but also more coal consumption. Therefore, it is of great significance to actively take precautionary measures and greatly reduce the shut-down failure caused by the abrasion of fly ash in the already-built utility boilers under the condition of not being able to change their structure. In the past two years, our factory has done a little work in economizer wear-resisting and obtained
