    摘要: A system and method for reducing NOx emissions from a lean burn combustion source is provided. The system includes a blower passing air through a continuous duct having a hot portion and a reaction portion. The hot portion of the duct is positioned in the convective zone of the combustion source to heat the passing air for the reaction portion of the duct. An injector attached to a urea storage container is positioned in the reaction portion of the duct and sprays urea from the storage container into the heated air in the reaction duct for evaporation and decomposition into ammonia gas. The ammonia gas is then supplied to an injection grid in the exhaust duct of the lean burn combustion source upstream of a NOx reduction catalyst. The injection grid supplies the ammonia gas to the exhaust gas in the exhaust duct.

    摘要: A combustion system and method for a coal-fired furnace in which a burner divides a mixture of coal and air into a first stream containing most of the coal and a second stream containing most of the air. The first stream is discharged from the central part of the burner and the second stream is discharged through an annular passage surrounding the first stream in a combustion-supporting relation to the first stream. Additional air is discharged in varying amounts in a combustion-supporting relation to said streams.

    摘要: A large-scale combustion system has a fuel line having a burner end, a burner at the burner end of the fuel line, a source of fuel flowing through the fuel line to the burner, a hot surface igniter adjacent to the fuel line, a flame holder disposed adjacent to the hot surface igniter, and a source of igniter combustion air. The hot surface igniter is activated to ignite the source of fuel, the ignited fuel leaving the burner, and the hot surface igniter is protected from a heat caused by the ignited fuel. A flame detector detects ignition of the source of fuel and in response to detection of ignition the hot surface igniter is deactivated.

    摘要: A combustion system and method for a coal-fired furnace in which a separator-nozzle assembly divides a coal-air mixture into a first stream containing most of the coal and a second stream containing a much smaller quantity of coal. Another nozzle is provided which receives another mixture of coal and air and discharges same in a combustion supporting relation to said streams. At start up and low loads, the separator-nozzle assembly discharges a majority of the coal and air in a combustion supporting relationship and the other nozzle discharges a relatively low quantity of coal and air. At high load conditions, the other nozzle discharges a majority of the coal and air while the coal and air discharging from the separator-nozzle assembly is kept at relatively low values. A splitter is provided for receiving a coal-air mixture from a mill and splitting it into two separate mixtures.
