To continue our journey, we have focused on optimization of ESP charging & ESP heaters automation JK White Cement recognized with Rajasthan Energy Conservation Award-2020 by RRECL, Jaipur, SNEMA gold award-2021 and CII award for Power quality. Kiln Electrostatic Precipitator System ESP is used for gas cleaning in almost every major section of cement plant. The characterization of dust emission has been and clinker cooler, in terms of exit gas quantity, temperature, dew point, dust content and particle size. It is seen that all these characteristic have wide range of variation. Particle migration velocity varies directly with its size and proportional to the square and square root of applied voltage and absolute temperature of gas. Pulse energization allows the use of hot gas, besides reducing the dust emission and power consumption. various capacity expansion projects of ESP’s (6 No’s for Raw Mill & Kiln ESP and 3 Fields for Steam Exhaust ESP) are used Inside ESP Dust Particles are charged by charging particles capture negatively charged gas ions as the ions move toward the grounded collection plate. Scenario before implementation • transformers were feeded by controlled controllers) with 1:1 charging ratio. Field Insulator Heaters 36nos. Shaft Insulator Heaters 9nos. Hopper Heaters 30nos. 75 Heaters • Each ESP have number of Heaters (1 KW rating each) installed to maintain position. These Heaters remain ON almost continuously to maintain Temperature inside Heater chamber.
