Abstract For captive power station in oversea cement plants where weak power supply, based on the principle of "energy grade, step utilize", waste heat steam can be highly connected with reheating power generation unit since the high pressure cylinder exhaust steam from reheating turbine unit is similar to waste heat generated steam, thus the reheater of coal fired boiler can improve the waste heat steam quality and increase the total thermal efficiency and power output of the power generation unit. This article compares and analyzes the indexes and data of high temperature super-high pressure reheating unit with the regular high temperature high pressure unit + condensing waste heat power generation unit, which shows the coal consumption, self-power consumption and power output of super-high reheating unit are all optimized to high temperature high pressure + waste heat power generation unit. Land occupation, investment and system configuration are also compared for reheating unit and regular unit, which shows the direction of reheating unit application in captive power plants of other industrial area.
