Embodiment approach

[0044] A plurality of nozzles 3 located at the lower part of the furnace body 2 can be used to respectively introduce gasification agent and pulverized coal into the furnace body 2, wherein some nozzles 3 are used to introduce gasification agent, and the remaining nozzles 3 are used to introduce pulverized coal. The pulverized coal in the raw material is carried by the carrier gas into the furnace body 2 through the pulverized coal channel 32 in the nozzle 3 by way of gas transportation. As an embodiment, the carrier gas is nitrogen.

[0045] As a preferred embodiment of the present application, the furnace body 2 is a pressurized furnace body.

[0046] As a specific embodiment of the present application, the plurality of nozzles 3 are single-channel nozzles with only one channel. Among them, the passages in several nozzles 3 are pulverized coal passages 32 for introducing pulverized coal into the furnace body 2 ; the passages in the remaining nozzles 3 are gasification agent p...

Abstract

The present application discloses an integrated gasifier of lump powder and a method for integrated gasification of lump powder. The lump-powder integrated gasification furnace includes a furnace body and a plurality of nozzles located at the lower part of the furnace body. The top of the furnace body is provided with a lump coal inlet for adding lump coal into the furnace body. It is characterized in that at least one nozzle has a The pulverized coal passage for adding pulverized coal to the furnace body. The lump-powder integrated gasifier solves the balance problem of lump coal and pulverized coal in coal gasification projects by using both pulverized coal and lump coal as raw materials, greatly improves the utilization rate of natural coal mine products, and also improves the melting efficiency. The gasification intensity of the slag gasifier reduces the one-time investment cost and operating cost, and further improves the economic benefits of the coal gasification project.

Description

technical field [0001] The application relates to a gasifier and its application in a coal gasification process, which belongs to the field of coal chemical industry. Background technique [0002] In the process of coal gas production, commonly used gasifiers are divided into entrained bed gasifiers, fluidized bed gasifiers and fixed bed gasifiers. Regarding the fixed bed gasifier, please refer to Chinese Patent Application Publication No. CN103436296A. Fixed-bed gasifiers generally use lump coal as raw material. Although the price of raw materials is high, the investment and operating costs of fixed-bed gasifiers are low. Entrained bed gasifiers and fluidized bed gasifiers generally use pulverized coal as raw materials. Although the price of raw materials is slightly lower, the one-time investment and operating costs of entrained bed gasifiers and fluidized bed gasifiers are much higher than those of fixed bed gasifiers. gasifier. [0003] In the mining process of coal m...
