Embodiment

[0006] 1 Renovate the gas furnace in the existing chemical fertilizer plant, the gasification intensity index B = 1600 kg / m2·hour, and can realize continuous gas production, which can increase the efficiency by more than 10%, and reduce the cost of synthetic ammonia per ton by tens of yuan.

[0007] 2 Renovate the existing second-stage gas furnace, the gasification intensity index B = 1600 kg / m2·hour, and expand the types of gasification coal.

[0008] 3 Design a single-stage atmospheric fixed-bed gas furnace with gasification intensity index B = 1700 kg / m2·hour, which can gasify solid fuels such as bituminous coal and anthracite.

[0009] 4 Retrofit the pressurized gasification gas furnace, the gasification intensity index B = 1800 kg / m²·hour, the gasification agent pressure can be reduced by more than 90% compared with the original process, and the gasification cost is significantly reduced.

[0010] In addition, the gas generator installed in kilns and small boilers is desi...

Abstract

A gas generator is disclosed. Its features are high gasifying intensity (1600-1800 kg / sq.m.hr), broad spectrum of raw materials including soft coal, hard coal, coal gangue and combustible solid, and low cost.

Description

Technical field: [0001] The invention is an optimized new structure gas generator, thereby expanding its applicable coal types, lowering the cost and higher gas production. technical background: [0002] For existing domestic and foreign fixed-bed gas furnaces with constant pressure and equal diameter (such as 1984U.S.P4453950), the gasification intensity index is generally 180-380 kg / m 2 · Hours, poor adaptability of coal types, high cost of gas production. The gas furnaces of Chinese patents CN86106668 and CN87107583 adopt a furnace cavity structure with a small top and a large bottom, and the gasification intensity index is as high as 1100-1500 kg / m 2 Hours, the adaptability of coal types is expanded, and the cost of gas production is reduced. Invention content: [0003] Over the past ten years, in the promotion and application of this kind of gas furnace with a small upper structure and a large lower structure, after exploring, summarizing, improving and improving wi...
