To establish strict norms on pollution control, NTPC has introduced several environment friendly steps to control both water and air pollution strictly as per the norms of Orissa pollution control board for its 3,000 MW Kaniha Power Stations which consumes around 55,000 tonnes of coal per day.
Some of the major steps are elaborated below.
The plant is equipped with electro static precipitator having efficiency of more than 99% for controlling air pollution. The details of emission and environment related data of the plant are scrutinized by government authorities from time to time.
In the ash dyke, ample steps like earth cover and water sprinkling have been provided on dry portion of ash dyke to control fugitive dust emission and rotational discharge principle is followed to keep the dyke wet. Following the advice of Orissa State Pollution Control Board, the company has procured the most modern cast basalt pipes for replacement of existing MS pipes for the first time in Orissa.
A pilot project for use of ash in agriculture was taken up in Kamarei and Tumugula villages where it was demonstrated that use of ash increases yield and improves water absorption capacity. Some amount of imported coal is also consumed to reduce specific coal consumption.
