(一) 从前,电业职工們常說:“电厂只有除灰工作簡单”。的确,从技术角度来說,在自动化程度較高的电厂里,除灰是比較簡单,不易出問題的部分。但是,近两年来事实并不如此。随着我国电业生产的迅速发展,設备容量大量增加,除灰設备未能相应地赶上。更由于煤种多变,以及备品配件消耗較多,供应工作有时跟不上等緣故,除灰工作竟成了影响全厂正常生产的重大关鍵問題之一。由于灰多設备少,設备損坏率較高,厂內积灰很多。除灰的主要設备及铁路长期失修,路旁积灰无暇处理,有的地方几乎埋沒了軌道。不仅除灰任务經常完不成,除灰人 (a) In the past, workers in the electrical industry often said: “The power plant has only a simple ash removal work.” Indeed, from a technical point of view, ash removal is a relatively simple and difficult-to-problem part of a more automated plant. However, this has not been the case in the past two years. With the rapid development of electricity production in China, the capacity of equipment has increased significantly and ash removal equipment has not been able to catch up accordingly. Moreover, due to the variety of coal types and the high consumption of spare parts and accessories, the supply work has sometimes failed to keep pace, and the ash removal work has become one of the major key issues affecting the normal production of the whole plant. Due to the fact that there are few grey equipments and the equipment has a high damage rate, there is a lot of dust in the plant. The major equipment for ash removal and the long-term disrepair of the railways, there was no way to deal with ash deposits on the roadside, and there were almost no tracks in some places. Not only does the ash removal task often fail, except for the gray person
