Embodiment

[0006] 1 Transform the existing gas furnace of the 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 tens of yuan per ton of synthetic ammonia.

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

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

[0009] 4 Transform 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 with α=45°, gasificati...

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 present invention is an optimized gas generator with a new structure, so that the suitable coal types are expanded; the cost is reduced; and the gas production rate is higher. technical background: [0002] The existing atmospheric pressure equal-diameter fixed-bed gas furnaces at home and abroad (such as 1984U.S.P4453950), the gasification intensity index is generally 180 ~ 380 kg / m 2 ·Hourly, the adaptability of coal type is poor, and the cost of gas production is high. The gas stove of Chinese patent CN86106668 and CN87107583 adopts a furnace chamber structure with a small upper part and a large lower part, and the gasification intensity index is as high as 1100~1500 kg / m. 2 ·Hours, the adaptability of coal types will expand and the cost of gas production will be reduced. Summary of the invention: [0003] For more than ten years, in the promotion and application of this kind of gas stove with upper, small and lower structure, after exploring, summ...
