Industrialized Application of Multi-Nozzle Coal-Water Slurry Gasifier

A brief account is given of the flow distribution and coal gasification mechanism in the new-type multi-nozzle opposing coal-water slurry gasifier,with emphasis on the review of its industrial application.The successful industrialized operation indicates that such a gasifier has the characteristics of high gasification efficiency,stable operation of the gasifier,and large adjustable scope for the load.The active constituents(CO H2) in the syngas reach 84.9% in volume fraction,the carbon conversion is 98%~99%,the average mass fraction of the combustibles in the cinders is <10%,and a ton of methanol consumes 1.35 t of coal.The successful development of the gasifier will promote greatly the expansion of the coal chemical processing technology in China and also technical advances in relevant industries.
