减少燃煤电厂热力系统的工质泄漏,是挖潜增效、降低电厂热损失、提高经济性、节能减排的一项重要工作。通过计算热力系统工质是否平衡,可以来判断泄漏区域,寻找隐性和显性泄漏点,便于及时消缺,提高热效率。介绍了优化后的分段计算热力系统工质平衡的方法。实际应用案例说明,采用分段计算可行有效。
Subsection Calculation Method of Thermal System Working Medium Balance
Reduce working medium leakage of thermal system in coal-fired power plant system,is an important task to tap the potential synergies,reduce power plant heat loss,improve economy and save energy.By calculation of the thermal system working medium balance to determine the spill area,eliminate defects timely and improve thermal efficiency.This paper introduces optimized subsection calculation method of the thermal system working medium balance.The practical application case shows that using subsection calculation is feasible and effective.
