A cogeneration power plant for producing steam and electricity. A boiler burner receives fuel from a fuel source and a boiler combustion air/exhaust mixture from a boiler combustion air fan. An internal combustion engine receives fuel and air for combustion. The internal combustion engine drives an electricity generator for the production of electricity. A boiler combustion control system automatically monitors the boiler load and the combustion air and engine exhaust mixture oxygen level and temperature. The boiler combustion control system will then appropriately automatically adjust the speed of the boiler combustion air fan to provide a near stoichiometric mixture of fuel and combustion air and engine exhaust mixture so as to provide for a high burner temperature causing the reduction of NOx emissions in the boiler exhaust while maintaining a very high boiler operating efficiency. |
