摘　　要：对超临界压力直流锅炉中间点温度的控制进行了深入的分析。针对传统的煤水比控制的缺点,提出了比热量控制的方法。实践证明,对不同煤质,一定负荷下的比热量几乎是相同的,可以使汽温控制得更好。Analysis on temperature control at intermediate points of supercritical pressure once-through boiler was carried out.To overcome the deficiency of traditional control method based on coal-water ratio,a new way based on specific heat capacity is being proposed.It has been found that for different coals,the specific heat capacity is nearly the same for a certain load,which can make steam temperature control more precision.

关 键 词：超临界压力直流锅炉 中间点温度 水煤比 比热量
