METHOD OF OPERATING A FIXED BED DRY BOTTOM GASIFIER
摘要
<p>A method of operating a fixed bed dry bottom gasifier (10) includes feeding coarse particulate carbonaceous material (20) with an average particle size of at least 1 mm and an ash fusion temperature increasing agent (32) into a gasification chamber (14) of the gasifier to form a carbonaceous material bed, feeding a gasification agent (22, 24) into the gasification chamber, and gasifying the coarse particulate carbonaceous material in the gasification chamber to produce synthesis gas (30) as well as ash (28). The ash collects in an ash bed below the carbonaceous material and the synthesis gas and the ash are removed from the gasification chamber.</p>
