水煤浆燃烧飞灰含碳量的影响因素及控制

水煤浆是一种很有市场潜力的清洁燃料，控制飞灰含碳量是非常重要的。本文通过对茂名热电厂25℃炉燃烧水煤浆试验，针对飞灰含碳量大小影响因素进行分析，具体从水煤浆燃料的浓度、雾化状况、燃料特性、燃烧方式、锅炉负荷、空气过量系数等方面进行分析。

Factors Having an Influence on Carbon Content in Fly Ash During the Combustion of Coal-water Slurry and Their Control

Coal water slurry is a kind of clean fuel with promising market demand. During its combustion the control of carbon content in fly ash remains a problem calling for due attention. Through a combustion test of coal water slurry in Boiler No.2 of Maoming Thermal Power Plant the authors have analyzed the various factors, which are believed to have an impact on the carbon content in fly ash. Such factors include concentration of coal water slurry, atomization conditions, fuel characteristics, combustion modes, boiler load, excess air factor, etc.
