AN ALTERNATIVE SOLUTION TO ESP RECONSTRUCTION FOR THE COAL FIRING THERMAL POWER PLANTS
The mathematical modeling is performed of the efficiency of flue gas cleaning from fly ash particles of coal-fired thermal power plants, upon installation of a preliminary flue gas cleaning system that consists of a louvered dust concentrator and a battery cyclone, with the recirculation of flue gas from the battery cyclone outlet to the electrostatic precipitator pre-chamber. Based on the available experimental data for the fractional composition of fly ash downstream the boilers of coal-fired TPPs, the size distribution functions were calculated, of fly ash particles at each stage of the preliminary dust-cleaning process, as well as concentrations and modified particle size distributions, to be further used as the input data for designing options and scope of the reconstruction of existing electrostatic precipitators.
