Embodiment Construction

[0012] figure 1 Shown is a schematic diagram of one embodiment of a gasification apparatus 10 of the present invention for gasification of carbonaceous fuels, such as coal. In the embodiment of the present invention, the gasification device 10 is not limited to any specific gasification device. In some embodiments, the gasification device 10 may include a gasifier (SlaggingGasifier) ​​capable of generating liquid slag during operation. In some other embodiments, the gasifier producing liquid slag may comprise an entrained bed gasifier. During operation, a portion of the ash in the entrained bed gasifier may be removed in the form of slag, for example when the entrained bed gasifier operates at a temperature higher than the temperature at which the ash is melted. In addition, a portion of coal ash is produced as a dry fine powder and / or a black fine powder slurry.

[0013] like figure 1 As shown, the gasification device 10 includes a gasification device 11 . In some embodi...

Abstract

The invention relates to a gasification device. The gasification device comprises gasification equipment. The gasification equipment is used for gasifying carbon containing fuel to generate synthesis gas. At least one part of the gasification equipment is provided with a fireproof wall for forming a gasification chamber for gasification. The fireproof wall comprises a fire facing layer, a supporting layer and a cooling layer. The fire facing layer comprises a fire facing face. The fire facing face is used for forming the gasification chamber. The supporting layer surrounds the fire facing layer to support the fire facing layer. The cooling layer surrounds the supporting layer and cools the fire facing layer through the supporting layer. The invention further relates to a gasification method.

Description

[0001] This application is a divisional application of the Chinese invention patent application (application number: 201010137013.5, application date: March 29, 2010, invention name: fire-resistant wall and gasification device and method). technical field [0002] The present invention relates to a refractory wall (or high temperature resistant wall, RefractoryWall) and a gasification device and method provided with the refractory wall, in particular to a refractory wall and a liquid slag discharge gasification device provided with the refractory wall Device (SlaggingGasificationDevice) and method. Background technique [0003] Gasification plants, such as gasifiers, are commonly used to gasify carbonaceous fuels such as coal to produce a mixture of hydrogen and carbon monoxide, such as coal gas or syngas. The gasification of coal and other carbonaceous feedstocks not only has a lower environmental impact but also produces energy more efficiently than conventional combustion...
