摘要
针对燃煤发电厂降低大气污染物排放以满足环保要求,以某发电厂5号锅炉改造为例,介绍了实现循环流化床锅炉炉内脱硝、脱硫的原理,并依据该原理对炉内脱硝、脱硫系统提出了改造和优化调整试验方案。调整后的系统,实现了降低锅炉的NO_(x)和SO_(2)的原始排放、提高炉内脱硫和炉内脱硝效率的目的。
Aiming at reducing the emission of air pollutants in coal-fired power plants to meet the requirements of environmental protection,taking No.5 boiler of a power plant in Hulun Buir as an example,the principle of realizing desulfurization and denitration in circulating fluidized bed boiler is introduced.According to this principle,the experimental scheme of transformation and optimization adjustment of desulfurization and denitration system in furnace is put forward.The adjusted system reduces the original emission of NO_(x) and SO_(2) from the boiler and improves the desulfurization and denitration efficiency in the boiler.
