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 a lump coal-pulverized coal integration gasification furnace and a lump coal-pulverized coal integration gasification method. The lump coal-pulverized coal integration gasification furnace comprises a furnace body and a plurality of nozzles positioned at the lower part of the furnace body, wherein a lump coal feeding inlet is formed in the top of the furnace body for feeding lump coal. The lump coal-pulverized coal integration gasification furnace is characterized in that at least one nozzle is provided with a pulverized coal channel for feeding pulverized coal into the furnace body. The lump coal-pulverized coal integration gasification furnace solves a balance problem of the lump coal and the pulverized coal in gasification projects by using both the lump coal and the pulverized coal as raw materials, so that the utilization rate of natural coal mine products is greatly improved, and the gasification intensity of slag gasification furnaces is aslo improved at the same time, one-time investment cost and operating cost are reduced, and economic benefits of coal gasification projects are further improved.

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...
