time strengthen the gray ash bucket equipment maintenance to prevent gray ash blocked out the Big Dipper, can prevent the occurrence of secondary dust. boiler operating parameters deviate from normal Under the normal load in the boiler flue gas flow, exhaust gas temperature, flue gas dust concentration and other parameters with the design parameters of electrostatic precipitator or less the same as all the normal operation of electrostatic precipitator. If the boiler flue gas flow increases, smoke temperature, flue gas dust concentration increased, the electrostatic precipitator operating conditions will deteriorate, so that lower collection efficiency. When the boiler lowload running time, in order to stabilize bustion, must be input for bustion of heavy oil or diesel, resulting in flue gas temperature and increase in the viscous material. These viscous materials hypertrophy caused by cathoderay anode plate deposition, resulting in decreased efficiency of the electric field of the dust. If vapor leaks i n the boiler, flue gas will increase the humidity, although in a very short time because of smoke and quenched and tempered by lower resistance than the ash, dust removal efficiency will be increased, but a little longer, will seriously fouling ESP, In particular, when the disclosure of large, plate or scale, will reduce the life of precipitator. changes in coal If coal burning boiler changes in the design of its calorific value than coal with low ash coal than the design of high, it will increase its coal, flour mills, dust, ash equipment wear and shorten the maintenance cycle of the equipment. The use of low calorific value coal, the actual coalfired boilers will increase so that the volume of flue gas containing ash increased. This will make ESP more than dealing with the design of flue gas dust concentration values, collection efficiency will be seriously affected. In order to eliminate coal from the impact of changes in collection efficiency of electrostatic precipitator, dust removal equipment in the system under normal circumstances, each electrostatic precipitator should be carried out at least one of the characteristics of typical coal tests to determine the coal, electricity , vibration efficiency electrostat
