燃烧器和炉膛在锅炉运行中发生的问题及处理措施

Operation Problems of burners and Furnace and Solving measures

在火电发电厂运行中,燃用煤炭、石油和天然气的锅炉烧烧器和炉膛发生的问题最多,涉及到的问题最广,给电厂安全运行的影响也较大.当前,随着我国国民经济的高速发展,大批火力发电机组的投运,这类问题就更加突出。本文根据国内外火力发电厂的大量运行经验以及近年来电厂锅炉烧烧器和炉膛发生过的事故分析资料,较全面地归纳、整理、总结出各类燃烧器和炉膛在运行中发生的各种各样的问题及相应采取的处理措施,无疑对杜绝这类事故,提高电厂的安全可靠性和运行经济性将有较大的实用性,同时,对电力设计院和锅炉厂的工程技术人员也都有一定的参考价值。

In operation of the thermal power plants,the prob-lems of the burners and furnaces fired—coal/petroleum/natural gas occured so frequent that the safe operation ofthe plants was affected seriously.The paper induces,sortsout and summerises various problems and relative solvingmeasures in accordance with both a number of operatingexperiences at home and abroad and the current imforma-tion of analyzing failures.It is of practicality and referencevalue.
