The Chandrapur Super Thermal Power Station (CSTPS) has officially conceded that its plant was emitting black smoke from its stack (chimney) of unit no. 6 on September 5. However, the plant management underplayed the day-long emission while left a back cloud hanging over a part of the city, claiming that they don’t have technology to control the emission during the light up (re-starting) after shutdown of every generation unit.
TOI had brought to fore high emissions from the plant on September 5, based on a complaint lodged by environmentalist Dr Yogeshwar Dudhpachare. CSTPS chief engineer Pankaj Sapate explained that the coal fired thermal power plant uses furnace oil or light diesel oil to ignite the boiler first, and after the furnace reaches a desired temperature, pulverized coal is used to generate electricity.
“This activity may take eight to 10 hours to reach the desired parameters of the furnace, and during this time black smoke may rise from the stack. However, Electrostatic Precipitators (ESP) are tuning up during such time to arrest dust particles,” he elucidated. He maintained that as it is a technical part of the boiler light up, scientifically it can’t be skipped.
He maintained that there is no proven technology in the thermal power industry to completely capture the black smoke emitted from the stack during the light up process. He maintained efficient pollution control equipment is installed in the plant to arrest regular emissions.
