摘要： A dual fuel burner including an elongated supply pipe and a gas injector for a boiler furnace having a plurality of peripheral openings around a center opening. The peripheral openings are pitched radially away from the longitudinal axis of the gas injector and also pitched either clockwise or counter-clockwise, to impart a swirling motion to gaseous fuel exiting the injector through the openings. A first sleeve member is concentrically spaced about the supply pipe and the gas injector to form an inner annular passageway for conveying a mixture of primary air and pulverized coal to the furnace combustion zone. A second sleeve member is concentrically spaced about the first sleeve member to form an outer annular passageway for conveying secondary air to the furnace combustion zone, and a plurality of circumferentially spaced vanes mounted within the outer annular passageway for inducing a swirling motion to the secondary air discharging from the outer annular passageway into the furnace combustion zone.

摘要： A steam generating boiler having a matrix means for reducing combustion volume. Matrix means is placed in the combustion furnace of a steam generating boiler, preferably downstream of fuel and oxidant stream. Matrix means produces a shorter combustion envelope than that of a conventional boiler, allowing for reduced volume steam generating boilers.
