Coal Research group of BHEL is
primarily engaged in the development of equipment and systems for clean coal technologies.
Major activies/achievements:
Carried out feasibility and
techno-economic studies and mathematical modelling for advanced power cycles. Over thirty
reports have been prepared.
Pressurised fluidised bed
combustion (PFBC) - Extensive studies have been carried out in the area of fluidisation
and heat transfer using a 440 mm PFBC pilot plant. Facilities available for further
development.
Pressurised fluidised bed
gasification (PFBG) - Development facilities of 100 mm dia., 200 mm and 440 mm dia, are
available to carry out gasification studies. Based on the work carried out here, a 168
tpd. PFBG was developed and integrated with 6.2 MWe IGCC test facility at BHEL
Trichy unit. Also associated cold model fluidisers are available for fluidisation as well
as scale up studies.
A pilot plant for high
temperature and high pressure granular bed filter established. Considerable data generated
to integrate with advanced power cycles.
Other areas of activities are
reformation of methanol, pneumatic solid transportation, characterisation of lime and
dolomite and on-going development of dynamic classifier for bowl mills.
Earlier this group had designed a
moving bed gasifier which was used with a 6.2 MWe IGCC demonstration plant. This plant was
the first of its kind in Asia and fourth in the world. This group has also sold the design
of a combined PFBC and PFBG test facility to ESKOM of South Africa.
