Generating device for coal gasification

Abstract

The invention discloses a generating device for coal gasification. The generating device for coal gasification comprises an upper furnace body vertically arranged and a lower furnace body perpendicular to the upper furnace body, wherein an upper combustion chamber is arranged in the upper furnace body, a feeding port is formed in one side of the upper furnace body, a lower combustion chamber is arranged in the lower furnace body, the lower combustion chamber is communicated with the upper combustion chamber, the upper furnace body sequentially comprises a first straight cylinder section, a hollow circular truncated cone shaped transition section and a second straight cylinder section from bottom to top, and the second straight cylinder section is greater than the first straight cylinder section in diameter. The transition section is internally and upwards provided with multiple circles of dust blocking plates from one end close to the first straight cylinder section in a surrounding mode, each circle of dust blocking plate faces the center, each dust blocking plate and the dust blocking plate circles participating in surrounding form oblique downward angles of 30 to 60 degrees, and every two dust blocking plates are not in contact. The generating device can make flue gas flow more smoothly by arranging different diameters of straight cylinder sections in a furnace and is provided with the dust blocking plates, the problem that ash is easily entrained in flue gas is solved, and the fuel utilization efficiency is improved.

Description

technical field [0001] The invention relates to the field of coal gasification equipment. More specifically, the present invention relates to a coal-to-gas generator. Background technique [0002] Coal gasification technology is the basis for the development of process industries such as coal-based chemicals, coal-based liquid fuels, combined cycle power generation, and hydrogen production, and is the key technology and leading technology in these industries. The existing carbon-containing fuels such as coal and coke can be gasified. Among the gasification technologies using entrained flow bed, the representative dry coal powder gasification technology mainly includes: the multi-burner technology developed by East China University of Science and Technology and other units. Opposite dry coal pulverized gasifier, Shell gasifier, E-Gas gasifier, GSP gasifier and two-stage dry coal pulverized gasifier of State Power Corporation Thermal Engineering Research Institute.
