Research regarding an Afterburning System from a Cogeneration Power Plant on Gas Fuel

The global efficiency increase for cogeneration with gas turbines depends on the heat utilization from the burned gases of the turbo-engine, and it is achieved with a reutilization boiler. Introducing afterburning not only increases the efficiency of the cogeneration but it also increases the flexibility of the turbo-generator, boiler and afterburning assembly. An afterburning installation has been tested at different working regimes with the turbo-generator and the boiler measuring pollutant emissions. Data was processed and the optimal regime, i.e. minimum emissions, was obtained. A numerical model for the burning process was developed and the concordance with the experimental data was analysed.
