摘要： Process is described for reducing emissions of nitrogen oxides and carbon monoxide from fuel gas fired boilers by using a computer to closely control the flow rate of combustion air and by installing a duct to allow flue gas to recirculate into the air intake of the boiler. In most cases strict emission standards can be met without making any other mechanical modifications to the boiler. A computer controller maps burner characteristics and controls both a variable speed drive and the damper on the combustion air fan, and a damper on recirculated flue gas to meet emission requirements over the various firing rates while maintaining a stable flame free of pulsations. In some burners a simple cone structure placed in the burner provides additional flame stability.

摘要： 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.

摘要： 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. Combustion occurs inside the burner and hot gases are generated which are used to provide heat for the boiler. An internal combustion engine receives fuel and air for combustion. The internal combustion engine drives an electricity generator for the production of electricity. An engine jacket and oil cooler are utilized to provide cooling for the engine. A water circuit is configured to remove heat from the engine jacket and oil cooler. The heated water flows through a water-to-air heat exchanger connected to the water circuit. The water-to-air heat exchanger utilizes the heated water to heat ambient air through the heat exchanger to produce heated boiler combustion air. Engine exhaust from the internal combustion engine combines with the preheated boiler combustion air in a boiler combustion air fan for producing a boiler combustion air/exhaust mixture for the burner. A boiler exhaust duct directs boiler exhaust away from the boiler. 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.
