First of all it is an statutory requirement of Govt. of
India.It is mandatory to instally CEMS on the stack of your
power plant.

CEMS is a system of online monitoring of the constituent
gases coming out of your boiler.Qty of SOX,NOX,CO,CO2,N2
and O2 as well as exit temperature is measured on a
continuous basis.

CEMS is vital to ascertain the performance of the boiler
e.g excess O2 emission infers that you are supplying excess
air which would cool your boiler.In order to heat this
excess air you will be supplying extra fuel.Thus decreasing
the efficiency of boiler.Similarly the qty of CO would mean
less air and thus incomplete combustion in the boiler.

SOX and NOX are measured for environmental reasons.

Hope this bird's eye description of CEMS satisfies your
query.
