Study on denitration technology of coal-fired boiler at full load in Shengli Power Plant
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.
