600 MW机组SCR脱硝系统运行特性
Operation Characteristic of SCR Denitration System of 600 MW Unit
摘要
Abstract
With increase of installation capacity of coal-fired thermal power units,emission of nitrogen oxide is continuously increasing,which has caused a series of environmental problems.Therefore,the paper analyzes working principles and sys-tem constitution of the selective catalytic reduction (SCR)fuel denitration system.Then on the basis of data supervised by the distributed control system (DIS),it studies dynamic variation laws of other relevant parameters such as load,ammonia spray amount,and so on by combining denitration reaction mechanism as well as static variation laws of denitration efficien-cy with variation of factors including load,ammonia nitrogen molar ratio,oxygen amount,and so on.Analysis results can provide references for design of the SCR automatic control system.关键词
