In the overall assessment, taking a production of
six million tonnes of sponge iron during the year
2006-07 through viable CDM projects, there is a
potential of producing 420 MW power through WHRB
with an annual carbon credit of 1.26 million CERs.
Basis : (1) waste gases from a 350 tpd kiln can
produce 7 MW power
(2) 1 MW power on an average can attract 3000
CERs annually
By the year 2011 – 12, with the anticipated doubling
of production of sponge iron in India, the power
generation and corresponding CERs would also be
doubled to realize a credit of 2.52 million CERs
annually.
How to Improve viability of WHRB Systems
The viability of the waste heat recovery system, in
general, can be enhanced, if the following are
considered :-
(i) permitting open access and inter-state wheeling
of power from sponge iron sector at a reasonable
tariff without any stricture from the State
Governments. A waste heat recovery system based
on 350 TPD kiln can generate about 7 MW, out of
“When everyone tries, the team flies.”
which 1.5 MW can be used for captive consumption
in sponge iron making and a surplus of 5.5 MW can
be wheeled to the grid.
(ii) reserving and making available non-coking coal
of high ash fusion temperature and high reactivity
for sponge iron sector.
(iii) allocating iron ore mines to sponge iron
manufacturers, and
(iv) extending carbon credit to the manufacture of
fly ash bricks.
Pre-heating of kilns - another CDM option in
the arena of energy efficiency
As an innovative step, it may be worth exploring
installing rotary pre-heating section as an adjunct
to sponge iron kilns, where the waste hot gases from
the kilns can pre-heat the raw materials in the kilns
in the vicinity of 750oC. This would reduce heat
losses entailing lower coal consumption and
enhanced production of sponge iron. While the
gains are yet to be quantified through some plant
trials, prima facie, it could attract CDM benefits owing
to significant saving of fossil fuel. These projects
can be viewed in the ambit of energy efficiency
measures.
