无烟煤飞灰循环增压流化床燃烧试验研究

Experimental Investigntion on Anthracite Combustion Characteristics in a Pressurized Fluidized Bed with Fly-ash Recycling

在ＳＥＵ－ＰＦＢＣ装置上进行了阳泉无烟煤燃烧试验．研究了流化速度、床层深度和床层温度对燃烧效率的影响。试验结果表明，采用飞灰循环回燃后燃烧效率可达９９．８％．

Yangquan anthracite combustion test was conducted on a SEU-PFBC plant. Studied was the effect on combustion effidency of fluidizing speed. fluidized bed depth and temperature. Test results show that a combustion efficiency of 99. 8%can be attained with the use of recycled fly-ash.
