Abstract
High-efficiency ultra-supercritical secondary reheat technology has become an frontier technology representative for the thermal power industry.Pipeline efficiency is one of the key factors affecting the thermo-economic performance of this technology.To study the reasonable value of pipeline efficiency for high-efficiency ultra-supercritical secondary reheat units,this paper takes the boundary conditions under THA conditions of a domestic 1 000 MW high-efficiency ultra-supercritical secondary reheat unit as an example,and adopts an anti-balance pipeline efficiency calculation scheme.The results show that the pipeline efficiency value can be increased from the conventional 99%to 99.5%,which can further improve the overall efficiency and performance of the unit.关键词
