Abstract: A pulverized coal gasification device and process for producing high heating value coal gas with low carbon residue content includes a U-shaped coal gas generation furnace and a coal gas-semicoke separating device, and the U-shaped coal gas generation furnace consists of two section structures including high-temperature and low-temperature sections which are arranged in a U-shaped manner; the high-temperature section and the low-temperature section share an ash hopper; the high-temperature section is a downward entrained-flow bed, and the low-temperature section is an upward entrained-flow bed; and an inlet of the coal gas separating device is connected to the outlet of the low-temperature section, a solid outlet of the coal gas separating device is connected to an inlet of the high-temperature section, and a gas outlet of the coal gas separating device is connected to a coal gas waste heat utilizing and purifying system. The coal utilization rate can be greatly increased.

Abstract: An air preheating and denitration integrated reactor and reaction method. The reactor includes a rotary catalyst body, housing arranged outside the rotary catalyst body, and gas inlet and outlet channels on upper and lower surfaces of the housing; the gas inlet and outlet channel is in divided three, namely flue gas, reductant, and air inlet and outlet channels, the rotary catalyst body is cylindrical and includes a central shaft rotor and multiple circular catalyst layers rotate around the central shaft rotor, each circular catalyst layer is divided into air, flue gas and reductant zones by a radial sealing plate and axial sealing plate. In each circular catalyst layer, a catalyst in the reactor alternately circulates in flue gas, reductant and air zones. The catalyst performs heating-reheating-cooling process on catalyst layers along with the reactor rotation, different temperatures and reaction atmospheres in zones conductive of air preheating and denitration.
