某超临界600MW机组中联门参调供热经济性研究

Study on Economy of a Supercritical 600 MW Heating Unit with Intermediate Pressure Combined Steam Valve Participating in Regulation

对于中联门参调供热机组,需要根据不同煤价对汽价进行调整,以保证电厂盈利.文章以某600 MW超临界机组为例,分析了不同煤价情况下的盈利情况,并比较售汽和纯售电的经济性,给出建议的售汽方案,并对供热机组实际运行给出了建议.

For the heating unit with intermediate pressure combined steam valve participates in the regulation,under different coal prices,the steam price needs to be adjusted to ensure the profitability of the power plant.Taking a 600 MW supercritical unit as an example,this paper analyzes the profitability under different coal prices,compares the economy of steam and electricity sales,gives the proposed steam sales scheme,and gives some suggestions for the actual operation of heating unit.
