Abstract

Abstract: Taking the 2×350MW supercritical coalfired heat supply unit as example, the feasibility, reliability and economical efficiency of the condensate extraction and backpressure (NCB) installation scheme were analyzed. To adopt the NCB technical scheme can improve the heat supplying capability and the economical efficiency of the unit significantly.

Key words: coal-fired heat supply unit, condensate extraction and backpressure (NCB) technology, installation scheme, economic analysis
