However, suppliers were working on the same and have
assured us that their R&D teams were being informed
about the same and shall work and inform back to us once
the development was successful.
NOX Guarantee
As the government norms are getting stringent day by day
and presently the norms suggest that NOX emissions shall

on the latest technologies available and advancements in
the systems so that without the use of SNCR we could
achieve the emission norms, as the operation cost impact
of ammonia consumption is approximately Rs 3.5 lakhs/
year for reduction of 1 mg/Nm^3. Thereby we had a very
serious round of discussions with all technology suppliers
for upgrading their technologies so that SNCR could be
avoided. Though M/s Thyssenkrupp India Limited was
reluctant to guarantee the NOX emission <600 mg/Nm^3
without SNCR, they agreed to carry out R&D and come
up with a positive solution in the future.
Our team had discussed with and convinced suppliers
that if the supplier could have pre-conditions for
performing and calculating the Performance Guarantee
(PG) parameters, the buyers could have a few too. Not even
one supplier agreed to the same, but we kept on discussing

PG document. If there is any change in these parameters,
