低压锅炉在锅筒和集箱底部的定期排污,能有效地排除锅内水渣污物、降低炉水盐碱度,改善蒸汽的品质,通常被作为低压锅炉的主要排污方式。这种排污操作的效果在某种程度上受司炉工实践经验,工作责任心以及其他因素等的制约。在统一组织的司炉工安全技术培训班的实践考试中,司炉工在锅炉定期排污操作中,如何选择恰当的排污时机,控制排污量,采用合理的排污操作保养方法,常常有不少的争论。其中反映的某些做法,显然对锅炉的安全经济运行会产生不利的影响。现提出一些粗浅的看法,供广大司炉工人参考。
Low-pressure boilers at the bottom of the drum and the tank regularly sewage, waste water can effectively exclude the dirt, reduce water salinity, improve the quality of steam, is often used as a low-pressure boiler main sewage. The effectiveness of this blowdown operation is somewhat conditioned by the experience of the fireman, the job responsibility, and other factors. In the practice of the unified fire department safety technology training course, it is often a lot of controversy that the fireman should choose the proper blowdown timing, control the amount of blowdown and adopt proper blowdown operation and maintenance methods during the regular blowdown operation of the boiler. Some of the practices reflected therein obviously have a negative impact on the safe and economical operation of the boiler. Now put forward some superficial views for the majority of Stove workers reference.
