Embodiment Construction
[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0034] Such as figure 1 As shown, a new gasification process burner with micro-channel circulation cooling, including a central gasification agent channel 1, a fuel channel 3 coaxial with the central gasification agent channel 1 and sequentially sleeved outside it, and an outer gasification agent channel 4. The cooling water passage 2 arranged between the central gasification agent passage 1 and the fuel passage 3 , between the fuel passage 3 and the outer gasification agent passage 4 , and outside the outer gasification agent passage 4 .
[0035] The fuel in the fuel channel 3 is coal water slurry or dry coal powder;
[0036] The gasification agent in the central gasification agent channel 1 and the outer gasification agent channel 4 is water vapor, carbon dioxide or a mixture of both.
[0037]Preferably, each of the cooling water ...

The invention provides a novel micro-channel circularly cooling gasification process nozzle. The nozzle comprises a center gasifying agent channel, a fuel channel, an outer gasifying agent channel and cooling water channels which are distributed between the center gasifying agent channel and the fuel channel, between the fuel channel and the outer gasifying agent channel and outside the gasifying agent channel, wherein the fuel channel and the outer gasifying agent are coaxial with and sequentially sleeved on the center gasifying agent channel; the water intake channels of the cooling water channels are composed of a plurality of micro-channels; the flowing speed of high-pressure cooling water increases in the micro-channels, and the center gasifying agent channel, the fuel channel, the outer gasifying agent channel and metal wall surfaces of the cooling water channels are efficiently cooled in heat conduction and forced-convection heat transfer modes; cooling water is sprayed from the micro-channel outlets in a high-speed jet manner, and the bottom metal wall surfaces of the cooling water channels are effectively cooled in a forced impact jet convection heat transfer manner, and then the cooling water flows back to the water outlets of the cooling water channels from a return channel. The novel micro-channel circularly cooling gasification process nozzle can be used for overcoming the defect of the gasified nozzle technology in the prior artthe nozzle is poor in cooling effect and has a short service life.
Description
technical field [0001] The invention relates to the field of coal gasification, in particular to a novel microchannel circulating cooling gasification process burner. technical background [0002] Coal is an important energy source, but for a long time, the use of coal has been accompanied by serious environmental pollution. In recent years, people have paid more and more attention to clean coal technology aimed at reducing pollution emissions and improving utilization efficiency; coal gasification technology, as one of the coal processing and conversion technologies, is considered to be one of the most efficient and clean clean coal technologies. [0003] Coal gasifier is a device that converts fossil fuels (powdered coal, petroleum, natural gas, etc.) into coal gas, and is widely used in chemical industry, nitrogen fertilizer, gas, combined power generation and other fields. In view of our country's poor oil, little gas, and more coal resources, the gasification fuel in m...
