Some
of the prevalent clean coal technologies and steps being
taken to adopt these technologies in India are as follows:
(i) Supercritical Technology
In India supercritical units of 660
MW are under installation at Sipat and Barh Thermal
Power Stations(TPS) of NTPC Ltd. Apart from these, a
number of supercritical units with unit size of 660/800
MW have been planned to be set up by NTPC Ltd. and State
utilities. Ultra Mega Power Projects are also envisaged
to be with supercritical parameters.
(ii) Circulating Fluidised Bed
Combustion (CFBC) Technology
Four CFBC units of 125 MW each are
operating at Surat lignite TPS and Akrimota TPS in Gujarat.
Six CFBC units of 125 MW each are under execution at
Surat Lignite, Giral TPS and Barsingsar TPS. CFBC units
of 250 MW are being installed at Neyvelli by Neyvelli
Lignite Corporation.
So far the world over, IGCC technology
has been adopted for low ash coal which is not suitable
for Indian high ash coal. In India, efforts are underway
to develop this technology through indigenous efforts.
Supercritical generating units are
being manufactured by a number of countries viz, USA,
Japan, Germany, Korea, Russia, China etc. BHEL has also
on-going collaboration for manufacture of supercritical
boilers and turbine generators with M/s Alstom and M/s
Siemens respectively. M/s Larsen & Toubro Limited
(L&T) has also formed a joint venture company for
manufacture of supercritical boilers and turbine generators
with M/s Mitsubishi Heavy Industries (MHI), Japan.
CFBC boilers are already being manufactured
in India and BHEL has been supplying boilers and turbine
generators for 125 MW and 250 MW supercritical units
installed by power utilities.

Union Minister for Power, Shri Sushilkumar Shinde in
the Rajya Sabha today.
