1. We cannot accept addition of supplementary burner because gas turbine package does not allow any supplementary burner in order to prevent the explosion.
We would suggest that the steam production be lowered down to 9,000 kg/hr
2. Because NOx value in flue gas is higher than Thai regulation, we need to treat it by installation of SCR. If HRSG cannot install SCR inside, we are afraid that it might be a big problem in term of environment.
We would suggest that SCR (different package) be installed after the GT before the HRSG.
We hope that the above is in order. Thank you very much.
