添加石灰石脱硫对CFB锅炉热效率的影响

Increase limestone desulphurization to CFB thermal efficiency influence

瑞平热电厂循环流化床锅炉因故停加脱硫石灰石,锅炉的热效率有所提高。分析脱硫石灰石的添加对锅炉热效率的影响。结果表明瑞平热电厂石灰石添加比例偏高、石灰石颗粒偏大和一次风、二次风分配不合理是热效率不高的主要原因,指出今后的改进措施。

With stream power system as a research object,a mixed integer linear programming (MILP) model which considered that the switching cost、maintenance cost and reasonable linearization of requirements models was established.By using LINGO to obtain a scheduling planning and the least operational cost for CCHP system in different cycle,massive operational cost can be saved.
