华东电网自1969年第1台400吨/时中间再热锅炉投产以来,到1980年止,已有21台投入运行,其中有燃油炉7台(包括吴泾热电厂7号炉改烧煤在内)、燃煤炉14台,总产汽量8400吨/时,发电容量261万千瓦,而华东三省一市火电装机为826.92万千瓦,故约占全网火电总装机容量的31.56%,是全网主力机组之一。为了提高机组的可靠性和经济性,1981年3月在徐州电厂召开了华东电网125机组第3次竞赛评比交流会议,重点交流了400吨/时锅炉燃烧调正、防磨、防爆等经验,并邀请网外有125机组的电厂及其主管局的锅炉专业人员参加。本文将就锅炉燃烧工况及其运行经济性等问题作些探讨。
East China Power Grid since 1969, the first 400 tons / hour since the middle of reheat boilers into operation, until 1980, 21 units have been put into operation, including 7 fuel oil furnace (including Wujing Thermal Power Plant No. 7 furnace to include coal) , 14 coal-fired furnaces with a total gas production of 8,400 tons / hour and a generating capacity of 2,610,000 kilowatts, while the thermal power installed capacity in three provinces and one city in eastern China reached 8,269,200 kilowatts, accounting for 31.56% of the total thermal power installed capacity of the entire network. One of the main crew. In order to improve the reliability and economy of the unit, in March 1981, the third competition review meeting of 125 units of East China Power Grid was held in Xuzhou Power Plant, focusing on exchange of experiences of combustion adjustment, wear prevention and explosion protection of 400 t / h boilers, Invited outside the network there are 125 units of the power plant and its Office of the boiler professionals to participate. This article will discuss some issues such as boiler combustion conditions and their operation economy.
