循环流化床锅炉脱硫对q_4和q_6的影响

Influences of Desulphurization of CFB Boiler Influences on q_4 and q_6

从灰平衡出发,利用钙硫摩尔比Ca/S,将脱硫剂石灰石纳入灰分,建立了循环流化床锅炉机械不完全燃烧热损失q4和灰渣物理热损失q6的数学模型。它适用于各种循环流化床锅炉。该数学模型的建立为循环流化床锅炉的设计和运行提供了简便、适用的计算公式。

From ash balance and using calcium to sulphur mole ratio, Ca/S, treating desulphurizing lime stone as a part of ash, a mathematical model is established for mechanical heat loss uncompleted burning,q_4, and physical heat loss of ash and slag,q_6 of CFB boiler, which can be applied to all kinds of CFB boilers and provides a simple and suitable calculating formula for design and operation of CFB boilers.
