ABSTRACT:
A method and apparatus for gasifying a solid fuel within a pressurized gasifier without a lockhopper, a slurry or pulverization comprising the feeding of said fuel into a charging chamber having a first section equipped with a ram through which a mandrel is disposed, and a second section within which an impervious seal is formed from the solid fuel by the compressive forces generated by said ram and a third section into which the seal is advanced while said ram forms a successive seal in said second section. The seal from said third section is reduced in size and charged into the pressurized gasifier where it is gasified without loss of pressure. The gases produced are utilized to polygenerate products such as transport fuels and electric power, and a fertilizer from waste gas resulting from the combustion of one of the produced gases.
