摘要/Abstract

摘要： 华电国际邹县发电厂三期2020t/h锅炉原设计燃用当地烟煤，近期由于煤炭形势紧张，燃料品质变化很大。煤种变化后一段时间内，炉燃烧不稳定，常出现燃烧不稳定现象或负压大幅晃动，蒸汽、再热蒸汽温度达不到要求，至因煤质差而导致锅炉灭火事故，给机组的稳定运行和经济运行带来了很大的隐患。分析了造成该种情况的主要原因并提出了针对性的解决办法，得了较好的效果。

Abstract: The designed coal of the 2020t/h of Huadian International Zouxian Power Plant project phase III is local soft coal. For the near term, the fired coal quality was changed greatly due to the insufficient coal supply. In a certain period after the coal grade was changed, the unstable boiler combustion was often occurred or the furnace negative pressure was rocked in largescale amplitude, and the temperature of main steam and reheated steam can not reach the required value; even the boiler flame out accident was happened. This became a serious potential hazard for stable and economical operation of unit. The reasons of this fault were analyzed. The relevant solution was proposed, and better result had been obtained.
