Hello,
Data I am provided with is as follows: a Gas engine with 2MW electric power and 48.5% efficiency powered by biogas during combustion of fuel with excess air equal to 2.2 emits 700 mg / m3 of nitrogen oxides. The exhaust gas temperature after the engine is 430oC. To reduce nitrogen oxides, a reduction chamber (RC) was installed behind the engine, in which the SNCR process will take place. Design a system for supplying gas burner installed in the RC (fuel biogas) if the engine is operating in an explosion hazard zone 1. Propose the solutions for use the energy of exhaust gas from the RC chamber to reduce the costs of reducing nitrogen oxide emissions. Prepare a technical and economic analysis for selected variants, including environmental impact.

I will be very grateful for any kind of advice on how to approach this project.
