煤粉预燃室是一种新型的预燃方法,能在较高的炉膛容积热负荷下缩小燃烧室容积,有助于提高燃烧的稳定性。利用预燃室作为锅炉的前置燃烧部件,对锅炉点火及低负荷稳燃时节约用油提供了新的途径。由清华大学热能工程系、上海吴泾热电厂共同研制成功的新型预燃室燃烧器(简称WQ型燃烧器),在锅炉点火启动和低负荷稳燃时,长期运行燃烧器不结焦。由于该燃烧器配有热工控制系统,投、停采用遥控、程控,操作简便、迅速,能保障电站锅炉安全运行,其经济效益显著,以一台220吨/时锅炉为例,启动一次就可节油5-10吨,参加调峰,每年可节油约
Pulverized coal pre-combustion chamber is a new type of pre-combustion method, which can reduce the volume of combustion chamber under the high heat load of the furnace volume and help to improve the combustion stability. Using the pre-combustion chamber as a front-fired combustion unit of the boiler provides a new way to save oil when the boiler is ignited and the combustion is stable with low load. By the Department of Thermal Engineering, Tsinghua University, Shanghai Wujing cogeneration plant jointly developed a new type of pre-chamber burner (WQ-type burner), when the boiler ignition and low load stable combustion, long-term operation of the burner does not coke. As the burner with thermal control system, cast, stop using remote control, program-controlled, easy to operate, quickly, to ensure the safe operation of power plant boilers, the significant economic benefits to a 220 t / h boiler, for example, start once Can save 5-10 tons, participate in peak regulation, annual fuel-saving about
