According to reports, Bharat Heavy Electricals Ltd (BHEL), Tiruchi, will focus more on developing clean fuel, carbon capture and storage technologies in the years to come. “We have made strides in achieving this through development of integrated gasification combined cycle (IGCC) technology,” said Mr A.V. Krishnan, Executive Director of BHEL Tiruchi complex.
The public sector power plant equipment major has also developed advanced ultra super critical equipment, aimed for cutting emissions at power units. The first thermal power plant using this technology will come up in Vijayawada. Though the cost, at Rs 9 crore a MW, is slightly more expensive, it will pay off with much lower running cost and carbon emission, he said.
After setting up a pilot project of 6.2 MW IGCC plant in Tiruchi, BHEL scaled up the design for the 182-MW Vijayawada plant. “Once all necessary clearances in place, the project can go on stream, hopefully by 2016-17,” he said.
According to Mr R. Kumar, General Manager (Engineering), BHEL Tiruchi, the efficiency level — a measure of how much heat energy embedded in coal is converted into electricity — in the proposed plant will improve to 42-43 per cent compared with the present 36-38 per cent. BHEL has also come out with design for 800 MW advanced ultra super critical (AUSC) steam generator.
The technology is being developed in association with Indira Gandhi Centre for Atomic Research and NTPC. This will further reduce emissions in power plants.
“We will do material testing for AUSC steam generator to evaluate the properties relating to corrosion and resistance very soon,” he said.
