摘要
Abstract
According to the problem of coking in the high-temperature reheater area of the four-corner tangential boiler in a certain power plant,it analyzes the causes of coking in detail and carries out combustion optimization adjustment tests,including primary air velocity leveling,pulverized coal fineness adjustment,secondary air adjustment and burnout air adjustment tests.After the unit is ope-rated in the adjusted manner,no obvious coking phenomenon occurred in the boiler.The combustible content of fly ash and slag decrease significantly,and the oxygen deviation on both sides of the operation decrease,ensuring the safe operation of the unit,improving the thermal efficiency of the boiler,and providing a reference for similar units of the same type with similar problems.关键词
