Abstract
An apparatus for the production of hot pressurized coal gas for use, for example, in power generation is provided. The apparatus includes a step of subjecting coal fuel to staged slagging combustion, to generate raw gas and liquid slag. The liquid slag is separated from the raw gas, and the raw gas is then subjected to a mixing and separation procedure, wherein it is treated and cleaned, for exampe of sulfur dioxide content. The raw gases may then be further treated and utilized to advantage in power generation. A preferred arrangement for conducting the process is also described.
