Abstract
With the overall goal of"3060"proposed,the energy and power sector is a key area and main battlefield for implementing the"3060"goal.Promoting the clean and efficient development of coal-fired power is an important measure to promote coal conserva-tion and carbon reduction in the energy industry.The coal-fired power industry has always regarded energy conservation and consump-tion reduction,as well as the construction of efficient and clean coal-fired power plants,as important development directions.This technical solution is based on a million coal-fired heating unit under construction in China,which utilizes low-level thermal energy in a reasonable cascade manner,studies the driving mode of the heating network circulation pump,fully utilizes the pressure difference be-tween the heating extraction steam and the heating network heater,drives the heating network circulation pump with heating steam,and the exhaust steam enters the heating network heater to heat the heating network circulation water.The energy cascade utilization technology can improve the thermal economy of the unit during the heating period,reduce the coal consumption for unit power supply,and lower carbon emissions.关键词
