Embodiment Construction
[0034] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.
[0035] Such as figure 1 , figure 2 and image 3As shown, the gasification burner used in the gasification of slurry fuel gasification to produce syngas according to the present invention includes a three-channel main body and a cooling system. Wherein, the three-channel main body sequentially includes a central channel 7 formed by a central nozzle 1, a middle channel 6 formed by a middle ring nozzle 2 and an outer ring channel formed by an outer ring nozzle 3 from inside to outside. 5. Preferably, several fixing flanges 19 are provided in the middle ring channel 6 and the outer ring channel 5 to ensure that the channels are in a coaxial state.
[0036] The center nozzle 1, the middle nozzle 2 and the outer nozzle 3 respectively include a center nozzle 8, a middle nozzle 9 and an out...

The invention discloses a gasification burner used for gasification of slurry fuel to produce syngas, which comprises a three-channel main body and a cooling system, wherein the three-channel main body sequentially includes a center nozzle from the inside to the outside. A central passage formed by the pipe, a middle passage formed by a middle nozzle, and an outer passage formed by an outer nozzle, the central passage is provided with a cyclone that makes the gasifying agent form a rotating jet, and the slurry The solid fuel enters the gasification burner from the middle channel, and the gasification agent is divided into two paths, one path enters the gasification burner from the central channel through the swirler, and the other path passes through the outer ring channel. into the gasification burner. The gasification burner described in the present invention adopts an internal rotation three-channel structure design and a combined cooling system. The overall structure of the gasification burner is simple, easy to manufacture and maintain, and can be used in the gasification of slurry fuel to produce syngas, and has a wide range of uses.
Description
technical field [0001] The invention relates to a gasification burner for producing synthesis gas, in particular to a gasification burner for producing synthesis gas by gasifying slurry fuel. Background technique [0002] The clean and efficient utilization of coal and other carbon-containing fuels has gradually become an important issue in today's energy utilization. Fuel gasification to syngas can provide leading technologies for modern chemical production, combined cycle power generation (IGCC power generation for short), and hydrogen production. At present, the gasification technology of coal and other carbon-containing fuels to produce syngas is generally divided into two categories, one is slurry fuel gasification technology, and the other is dry powder solid fuel gasification technology. Currently, the most widely used technology at home and abroad is Slurry fuel gasification technology. Moreover, as one of the key equipment of gasification system, the development o...
