云浮发电厂2号锅炉煤种适应性研究的应用实践

由于国内燃煤市场供应紧张，迫使广东粤电集团有限公司云浮发电厂420t／h无烟煤锅炉燃用非设计煤种。通过分析2号锅炉燃用非设计煤种后出现燃烧稳定性差、飞灰合碳量含量偏高等问题，有针对性地进行燃煤混烧适应性的试验研究，并在生产实践中及时应用，取得良好的经济效益，对同类型锅炉燃烧非设计煤种具有很好的借鉴意义。

Research and application of coal adaptability for Unit 2 boiler in Yunfu Power Plant

Due to the shortage of coal supply in china, the 420 t/h anthracite fired boilers of Yunfu Power Plant of Guangdong YUDEAN Group CO. ,LTD, have to use non-designed coal. In view the problems of Unit 2 boiler such as poor combustion stability and high combustible content in fly ash,multiple measures including mixed coal burning technique were researched and were adopted, Then, the good economical effects achieved. Thus, reference for coal changing operation of similar boilers is provided.
