燃煤锅炉低温余热利用技术应用分析

摘要

For the problems of the low use ratio of waste heat in thermal power plant boiler, the power plant deficit caused by raising the price of energy sources,and the gradually increasing of the environment stress, the reinforcing of the draining off water from boiler and the using of exhaust gas were carried out in order to save energy. The method of draining off water and using exhaust gas were introduced. An example proves that the economic benefit and environmental benefit of saving energy technique, which can provide a new way for enterprise to increase income, save energy and reduce emissions.%针对当前火电厂锅炉余热利用率低,能源价格上涨导致发电亏损,环境压力逐渐增大的现状,可通过加大对锅炉连排水和烟气余热的利用达到节能的目的.介绍连排水和烟气余热利用的相关技术方法,并分析其技术特点,通过实例进一步阐明应用节能技术后可以产生的经济效益和环境效益,为企业创收和节能减排提供一种新途径.
