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...

Abstract

The invention discloses a gasification burner for producing a synthetic gas through gasifying a fuel slurry. The gasification burner comprises a three-way main body and a cooling system, wherein the three-way main body sequentially comprises, from inside to outside, a center channel formed by a center jet tube, a center ring channel formed by a center ring jet tube, and an outer ring channel formed by an outer ring jet tube; a swirler allowing a gasification agent to form a rotary jet flow is arranged in the center channel; the fuel slurry enters the gasification burner from the center ring channel; and the gasification agent flow is divided into two paths, one path enters the gasification burner by going through the swirler, and the other path enters the gasification burner from the outer ring channel. An internal rotation type three-way structure design and the combined cooling system are adopted by the gasification burner of the invention. The gasification burner has the advantages of simple overall structure, convenient manufacturing and maintenance, realization of the application to the production of the synthetic gas through gasifying the fuel slurry, and wide use.

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...
