摘要(Abstract):
火电厂燃烧煤种往往不是设计煤种,燃烧煤种的比电阻有时会很高,导致电除尘器的除尘效率达不到设计指标,出口烟尘达不到环保要求。采用合适的电除尘器控制策略,将大大提高除尘效率,同时也降低电除尘器的电耗,以利打造绿色环保的现代化电厂。
There is often no designed burning-coal in thermal power plants.Specific resistance of coal combustion is very high,so the efficiency of electrostatic precipitator can not reach the design requirements,and outfall smoke can not reach the requirements of environmental protection.To adopt the appropriate control strategy will enhance the efficiency of electrostatic precipitator greatly.The power consumption of electrostatic precipitator can be reduced at the same time,to create a modern environment-friendly power plant.
