摘要
Abstract
To address the issue of low main and reheat steam temperatures in a pulverized coal boiler at a power plant,a combined method of furnace combustion simulation and thermal calculation was employed to study the influences of economizer surface area,flame center height,and coal type on the temperature reduction.Results showed that the change in flame center height was the primary cause of the low main and reheat steam temperatures.By comparing the effects of several technical measures,such as burner upward tilting,increasing the area of furnace refractory coating,and increasing the area of the reheater,it was determined that the optimal solution is to combine a 2°upward tilt of the primary air with an increase in the low-temperature reheater area.This solution has been adopted and implemented by the power plant.关键词
