New Delhi, May 27
TATA Steel would phase out completely the use of coal in generating steam and power from September and it would be done by recycling the by-product gases produced in the steel making process. This would help the company reduce its coal cost as well as control pollution levels further.
Mr R.P. Sharma, Chief of Environment and Occupational Health, told newspersons that the company was converting its coal fired boilers into gas fired boilers and would be using the gases generated in the blast furnace and the steel melting shop would be used to heat the boilers.
"This would result in an annual savings of around Rs 6-7 crore," Mr Sharma said.
He said the company is also planning to set up a rotary hearth furnace that would recycle all the solid wastes generated in the process of steel making. "This is a new technology. With this furnace, all the solid wastes containing iron can be recycled and made into hot bricketed iron which can then be rolled or can also be charged into the blast furnace," he said.
The company is also working to bring down its pollution level in the sinter plant under carbon trading treaty with Japan.
