Abstract: According to embodiments, a co-fired or multiple fuel combustion system is configured to apply an electric field to a combustion region corresponding to a second fuel that normally suffers from poor combustion and/or high sooting. Application of an AC voltage to the combustion region was found to increase the extent of combustion and significantly reduce soot evolved from the second fuel.

Abstract: A system and process are provided for converting a light hydrocarbon gas to a synthetic heavier hydrocarbon liquid. The system includes an autothermal reformer, a Fischer-Tropsch reactor and a Brayton cycle that are structurally and functionally integrated. In the practice of the process, a mixture of a hydrocarbon feed gas, a compressed air feed and process steam is fed to the autothermal reformer to produce a synthesis gas. The synthesis gas is fed to the Fischer-Tropsch reactor where it is catalytically reacted to produce heavy hydrocarbons. The outlet from the Fischer-Tropsch reactor is separated into water, a low heating value tail gas, and the desired hydrocarbon liquid product. The water is pressurized and heated to generate process steam. The tail gas is heated and fed with compressed air and steam to the Brayton cycle having a combustor and a series of power turbines and compressors. The tail gas and air feed are burned in the combustor to produce a combustion gas that is used to drive a power turbine linked by a shaft to an air compressor, thereby driving the air compressor. The system further includes a plurality of heat exchangers that enable heat to be recovered from the outlet of the autothermal reformer. The recovered heat is used to make the process steam as well as to preheat the hydrocarbon feed gas before it is fed to the autothermal reformer, preheat the synthesis gas before it is fed to the Fischer-Tropsch reactor and preheat the tail gas before it is fed to the combustor.

Abstract: A pulse combustor apparatus for burning solid fuel comprises a Rijke-type combustor tube and has a rotating fuel bed for defining a primary combustion zone adjacent the fuel bed. The rotating fuel bed tends to minimize agglomeration of solid fuel and accumulation of ash during combustion by agitating the solid fuel. An inlet conduit is provided for introducing a low nitrogen gaseous fuel to the combustion air upstream of the combustion zone to minimize the formation of NO.sub.x in the primary combustion zone. In other embodiments, inlets are provided downstream of the primary combustion zone for introducing additional air or gaseous, low nitrogen fuel for air staging or reburning to minimize the emission of NO.sub.x. Sorbents, such as limestone, are introduced above the bed to minimize SO.sub.2 emissions.
