Gas turbine exhaust

Dear Colleagues,

First of all wish you all, a happy & prosperous new year.

We are operating GE frame 7FA DLN 2.6 gas turbines in co-generation mode. We have online analyzers for CO, NOX & O2 to monitor exhaust emissions.

The units for CO PPM, NOX PPM & O2 in %.

I want to know how i can covert from PPM to Kg/KWH or tons.

online analyzers readings are as under.

NOX# 17.79 PPM
CO# 11.57 PPM
O2# 12.16 PPM

Exhaust mass flow# 434.61 Kg/sec
AIr inlet flow# 421.55 Kg/sec

Natural gas flow# 10.3 kg/sec

Natural gas composition are as under(measured through gas chromatograph)
