300MW循环流化床锅炉上部差压及床压优化试验
摘要
对锅炉上部差压及床压的控制优化进行了试验研究
并对机组经济性的影响进行了分析计算。结果表明
锅炉满负荷运行时
上部差压控制在0.8~0.9kPa(设计值为1.4kPa)
床压的运行控制值在15~16kPa较为经济合理
节能降耗效果明显。
Abstract
Tests were performed to optimize the control of bed pressure and pressure difference at upper part of a 300 WM unit CFB boielr.Moreover
the effect of optimization on unit economy was analyzed.The results show that
during the boiler's full load operation
the reasonable control range of the pressure difference at upper part of the furnace is from 0.8kPa to 0.9kPa(the design value is 1.4kPa)
and the bed pressure is from 15kPa to 16kPa
within which the energy saving effect will be significant.
