Abstract: A burner assembly (75) for the combustion of liquid fuels in furnaces (12) and the like. The assembly comprises fuel gun means (78) for creating a mixture of combustible fuel and an atomizing medium and injecting a stream of the mixture into the interior of a furnace; housing means (76) supporting the fuel gun means, attachable to the furnace, so that the combustible fuel mixture is delivered to the interior of the furnace for combustion and for supplying a first flow of air (B) into the furnace separate from the air mixed with the fuel to encompass the injected fuel mixture; and sirler means (79) having a plurality of blades (94) interposed within the housing means so that the first flow moves around and through the blades for imparting a rotation to the first flow of air to break up the stream of fuel mixture.

Abstract: A burner assembly (10) for the combustion of pulverized coal in furnaces (12) and the like. The assembly comprises wind box means (23) for providing a primary source of air to the interior (13) of the furnace; feeding means (30) for delivering pulverized coal through a wall (11) of the furnace and into the interior thereof; means for supplying (31) a secondary flow of air through the feeding means and into the furnace separate from the primary flow of air; and swirler means (32) having a plurality of blades around the feeding means so that the first flow moves around and through the blades for imparting a rotation to the primary flow of air to penetrate the pulverized coal funnel. A method for supplying pulverized coal to furnaces and the like through burner assemblies is also provided and results in increased combustion efficiency.

Abstract: An ignitor probe (10) for the ignition of burners and the like. The probe includes an elongate shaft (11) having an internal bore (14) passing therethrough and first and second ends (15,25), means for coupling (12) the probe to a power source, and an electrode assembly (13) carried within the internal bore and providing a centering couple (38), the centering couple communicating with one of the ends.

Abstract: An ignitor probe assembly (10) for the ignition of fossil fuel burners comprises in combination an ignitor (11) having a tip (70) activated by electrical energy and producing a temperature sufficient to ignite a fossil fuel, pipe means (12) for positioning the ignitor into the burner, means for carrying electrical power (13) to the ignitor passing through the pipe means adapter means (14) carried by the pipe means for the removable assembly of the ignitor thereto, and refractory insulator means (15) engageable with the means for carrying electrical power and interposed substantially concentrically within the adapter means for maintaining the means for carrying electrical power separate therefrom.
