200 MW 湿冷机组排汽余热供热利用方案对比分析

摘要

Taking the waste heat supply project of some power plant as the example,the paper compares the factors including heat pump and low vacuum heat-supply schemes,compares the waste heat ratio and coal-saving volume on the heat supply,and proves by the result that the power plant adopts the low vacuum heat-supply system which is more effective than the heat pump scheme.%以某城市电厂余热供热工程为例，对比了热泵与低真空供热两种方案，分析了余热占比、供热实际节煤等指标对供热的影响，结果表明，该电厂利用机组低真空排汽余热供热相比热泵供热节煤效果更明显。
