摘要
风能、光伏等新时代能源比例的不断增加对大型火力燃煤机组调峰的能力提出更高要求.在机组的运行负荷低于正常水平的情况,由于装置选择性催化还原(SCR)入口烟气温度降低至下限值,导致脱硝系统无法稳定运行.针对此问题,研究比较了几种全负荷脱硝改造方案,为机组全负荷脱硝的技术路径的选择提供借鉴.
Abstract
The increasing proportion of energy in the new era,such as wind energy and photovoltaic energy,puts forward Higher requirements for the peaking capacity of large coal-fired units.When the operating load of the unit is lower than the normal level,the denitration system cannot operate stably because the flue gas temperature at the inlet of SCR is reduced to the lower limit value.Aiming at this problem,this paper studies and compares several transformation schemes of full load denitration,which provides reference for the selection of technical path of full loaddenitration.
