Gasification furnace equipment and method for producing carbon monoxide

Abstract

The invention discloses gasification furnace equipment and method for producing carbon monoxide, and belongs to the technical field of coal chemical industry. The gasification furnace equipment comprises a gasification furnace with a combustion chamber, wherein along the axial direction of the combustion chamber, the combustion chamber is respectively provided with a pulverized coal pressurizing burner for spraying pulverized coal, oxygen and steam, a carbon dioxide nozzle for spraying carbon dioxide and a volatile matter-free carbon-based burner for spraying a volatile matter-free carbon-based raw material from bottom to top. The equipment is high in production capacity per unit volume and low in energy consumption. Correspondingly, by adopting the gasification furnace equipment to produce the carbon monoxide, the problem of producing the CO by taking CO2 as a reactant in the gasification furnace can be thoroughly solved, and meanwhile, the problem of gasification of biomass charcoal and a volatile matter-free carbon-based raw material on the entrained-flow bed gasification furnace is solved.

Description

technical field [0001] The invention relates to the technical field of coal chemical industry, in particular, to a gasifier device and method for producing carbon monoxide. Background technique [0002] Coal and oxygen enter the entrained bed gasifier through the burner to produce syngas, the main components of which are CO and H 2 , and a small amount of CO 2 , CO in the gasifier 2 The reaction with carbon is affected by the liquid slagging of the gasifier and the heat absorption of the reaction. The reaction depth is limited. Some gasifiers also produce high-pressure saturated or superheated steam. Cold air, chilled air is about 1 / 3 of the gas production of the gasifier, and the gasifier and auxiliary systems must be increased by 30% under the normal design. The production capacity per unit volume is low and the energy consumption is high, which directly affects the gasification Device operating costs. At the same time, there is no industrial operation precedent for en...
