Improvements of utility-based CHP heating systems

摘要

This paper proposes a novel mode of CHP heating system.This mode is characteeized by cascvade utilizatin of a wide effective temperature range of heat grid water at a low grade level.Modern energy-saving techniques and devices,nomally applied in relatively small scale and isolatedly from powr generating stations are now integrated into large-scale CHP heating system at a low-grade temperture level,so that the heat and power generation interact favorably oon each other and the unit fuel ocnsuption as well as the unit cost of the supplied heat are thus significantly reduced.Five sections are involved in the novel mode,as schematically shown in the Figure presented in the paper.
