Study on Operating Economy of Ultra-supercritical Units

Abstract

Under the same peak-regulating load rate, the economical efficiency of ultra- supercritical unit is superior than supercritical unit and subcritical unit. By comparing the ultra-supercritical unit, supercritical unit and subcritical unit, the bestload point of ultra-supercritical units could be achieved, which has a certain and positive effect to improve and maintain the steady and high economical efficiency operation state of the ultra-supercritical unit.
