This 9.84ft diameter two-stage coal gasifier is a high-quality second-hand industrial equipment acquired by our enterprise, which was originally served in a steel mill in Shanxi Province and professionally used for coal-to-gas production in steelmaking. It is currently stored in Kaifeng, Henan Province with sound overall condition, the steam drum and furnace body are structurally intact and undamaged, and only routine replacement of accessories for the motor and feeding system is required to restore efficient operation quickly, making it a highly cost-effective option for the coal-to-gas supply system of industrial enterprises.

This two-stage coal gasifier is a formally decommissioned equipment from a steel mill, which has been operated under stable load for a long time with excellent working conditions. The main components are free of damage and major overhaul records, and it can be put into use only after replacing conventional vulnerable accessories, with significantly lower investment cost compared with brand-new equipment. Available in stock in Kaifeng, Henan, inspection, testing, disassembly and transportation can be arranged at any time to realize rapid in-place installation and commissioning. It is an ideal choice for industrial enterprises in capacity expansion and transformation, equipment replacement and new gas station construction, combining practicality, stability and high cost performance to provide continuous, stable and economical gas supply guarantee for enterprise production.

The inner diameter of the furnace chamber of this two-stage coal gasifier is 9.84ft with a cross-sectional area of 76.1 square feet, which is compatible with a variety of commonly used coal types including non-caking coal, weakly caking bituminous coal, long-flame coal, gas coal and meager coal. The applicable fuel particle sizes are 20-40mm, 25-50mm and 30-60mm, the hourly fuel consumption is 2000-2600 kilograms, and the gas output can reach 5500-7000 standard cubic meters per hour. The low calorific value of the upper-stage gas is 7100-7500 kilojoules per standard cubic meter, and that of the lower-stage gas is 5000-5600 kilojoules per standard cubic meter. The gas outlet temperature is controlled at 100-150 degrees Celsius for the upper stage and 550-600 degrees Celsius for the lower stage, the furnace bottom blast pressure does not exceed 6000 Pascals, the gasification intensity is not less than 250 kilograms per square meter per hour, the dust content in gas is not higher than 50 milligrams per standard cubic meter, and the tar content is not higher than 20 milligrams per standard cubic meter. Adopting wet automatic slag discharge mode, the coal feeding system can be upgraded to fully automatic mode, all technical parameters are stable and up to standard, with high gasification efficiency and excellent fuel gas quality, which fully meets the gas demand of continuous industrial production.

Adopting two-stage gasification process, the equipment completes coal carbonization in the upper section and realizes high-efficiency gasification in the lower section, with sufficient tar cracking to produce clean and stable gas, which greatly reduces the load of the subsequent purification system. Meanwhile, it boasts strong adaptability to coal types, reliable safety performance and simple maintenance and operation. The equipment is equipped with a water jacket for self-produced steam, complete pressure and temperature monitoring devices, water seal and explosion-proof configurations, ensuring high operational safety. The main structure features strong durability, wearing parts are highly standardized with low replacement cost, bringing convenience for later operation and maintenance.

As a special coal-to-gas equipment for steel mills, it is mainly applicable to the iron and steel metallurgy industry, providing stable and reliable coal-to-gas supply for converters, heating furnaces, annealing furnaces and forging furnaces, effectively replacing natural gas to reduce production costs. It can also be used for heating various industrial kilns in refractory, ceramic and glass industries, supplying continuous gas for non-ferrous metal smelting, heat preservation and heat treatment processes, providing heat source for hot blast stoves, drying lines, reaction kettles and other equipment in the chemical industry, as well as clean gas supply for industrial boilers and steam stations, serving as a core gas supply equipment for industrial production in metallurgy, building materials, chemical industry, mechanical processing and other fields.
