概要
- 論文の詳細を見る
A single-stage pressurized fluidized bed gasifier was developed for producing low-heating-value gas from coal.<BR>Coal char was gasified by air-steam mixture at temperatures of 880 and 950°C and at pressures of 3, 5 and 7kg/cm<SUP>2</SUP>G. At the higher temperature of 950°C, char was gasified in the bed of silica sand particles in order to prevent ash agglomeration.<BR>Experimental data were analyzed on carbon conversion and the heating value of produced gas. The through-put of char was determined from the feed rate of air and the operating temperature.<BR>It was found that increase in operating pressure causes the elutriation of fine dusts from the gasifier.<BR>From the present experimental work several information was obtained useful to improve an overall process design.
