What are the impacts of changes in coal-fired boiler systems on industrial electrostatic precipitators?
The change of system parameters of coal-fired boiler has different effects on industrial electrostatic precipitator, for example, the change of smoke and dust concentration directly affects the efficiency of industrial electrostatic precipitator, which is reflected in the change of emission concentration. Although the change of air volume has little effect on the equipment, the dust removal of industrial electrostatic precipitator has little effect. The change of efficiency with air volume is very obvious.
If the flue gas temperature of coal-fired boilers is too low, condensation will cause shell corrosion or high-pressure creepage, but it is beneficial to the efficiency of dust removal; the increase of flue gas temperature and dust specific resistance is not conducive to dust removal, so the flue gas temperature directly affects the efficiency of dust removal, and the impact is more obvious. The physical and chemical composition of flue gas directly causes the change of specific resistance of dust, thus affecting the efficiency of dust removal, and has a great impact.
Industrial ESP is very sensitive to the distribution of airflow in the electric field. The distribution of airflow directly affects the efficiency of ESP. In the performance evaluation of ESP, the RMS index of airflow distribution is usually one of the important indexes to evaluate the performance of an industrial ESP.www.icleairs.com
