城市燃气锅炉房供热能力和余热利用
摘要
为了提取余热提升城市供热能力
介绍了郑州市燃气锅炉房供热现状和基于直接接触换热的烟气余热深度回收新技术
并对燃气锅炉供热能力进行了统计和分析。发现通过对燃气锅炉烟道改造和余热回收
燃气锅炉房的供热能力将达到1 600 MW
供热面积为0.35亿m

Abstract
For the purpose of extracting waste heat to improve the heating capacity of the city
the present situation of heat supply for Zhengzhou natural-gas fired boiler and the new technology of deep recovery of waste heat from flue gas based on direct contact heat transfer were introduced. It was found that through the reformation of the gas boiler flue and waste heat recovery
the heating capacity of the gas boiler will reach 1 600 MW
the heating area is 35 million m
