Abstract: The invention relates to a combined fluidized bed and pulverized coal combustion method and system. In the method, fluidizing air (4) is injected into a fluidized bed (2) situated in the bottom portio of the combustion chamber (3). Into the combustion chamber, to above the fluidized bed (2), is fed a mixture of pulverized coal and a carrier gas from a second set of fuel feed means (6) at a mass flow rate which is higher or at least substantially equal to the upper ignition limit of the mixture, and the mixture of the pulverized coals and the carrier gas at least by the fluidizing air (4), and at least a fraction of the fuel fed via the second set of fuel feed means (6) is combusted above the fluidized bed.

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: The proposed low-emission vortex furnace is intended for use in burning organic fuel and can be used most effectively for burning dust. The proposed low-emission vortex furnace comprises a combustion chamber (1) with a cold prismatic funnel (5) which has a slit aperture, and a device (7) positioned underneath the funnel and used for introducing the bottom blast. The furnace contains at least one burner (2) in the form of at least two fuel-air mixture feed ducts (2a, 2b), one duct lying above the other. Each of the ducts (2a, 2b) is provided with a device (3, 4) for adjusting the fuel/air ratio; this device ensures that the ratio of air to fuel in the upper duct (2a) is always higher than in the lower duct (2b). The longitudinal axes of the ducts (2a, 2b) are advantageously inclined so that the angle between the longitudinal axis of the lower duct (2b) and the projection of that axis onto the furnace wall is less than in the case of the upper duct (2a). The furnace may also be provided with a device (8) for feeding fuel of a particular fractional composition into each duct. During operation of this furnace, three operational zones are formed in the furnace chamber, namely, an ignition and active combustion zone; a reduction zone; and a re-heating zone. This reduces the quantities of nitrogen oxides produced while ensuring that the furnace is highly economical to operate.

Abstract: A method of reducing NO x produced by the burning of fuels includes providing a hydrocarbon and nitrogen mixture (10) to a plasma arc generator (20) for producing NO x reducing precursors (30) which are, in turn, provided near the burning of the fuel for reacting and reducing NO x emissions. These precursors (30) include N, H, HCN, CH i and NH i , etc.

Abstract: A pulverized coal combustion burner includes a pulverized coal nozzle (1), and secondary and tertiary air nozzles (70,80) provided in concentric relation to the pulverized coal nozzle. A flame stabilizing ring (5) is provided at an outlet end of the pulverized coal nozzle. A separation wall (2) is provided within the pulverized coal nozzle to divide a passage in this nozzle into two passages. A pulverized coal/air mixture flows straight through the two passages, so that recirculation flows of the pulverized coal/air mixture are formed in proximity to the outlet end of the pulverized coal nozzle. As a result, the ignitability of the pulverized coal, as well as a combustion rate, is enhanced, thereby reducing the amount of discharge of NOx.
