流化床条件下煤的一次爆裂特性的实验研究
EXPERIMENTAL STUDY ON PRIMARY FRAGMENTATION OF COALS IN FLUIDIZED BED
摘要
Abstract
The behavior of primary fragmentation in fluidized bed boilers shows some important effects on boiler operation including heat transfer, efficiency of carbon conversion and emission of fines. The primary fragmentation behavior of different lithotypes of the bituminous coal (clarain and durain) was studied and compared with each other in an atmosphericd fluidized bed. Particle size distribution curves are presented. The extent of fragmentation is strongly dependent on the size and chemical composition, and related to the lithotypes of the coal. It was found that the primary fragmentation behaviors of clarain and durain are different and there are some special size distributions after fragmentation. The experiments of different lithotypes are aimed at finding a relationship between macerals, mineral matter, volatile content, hardness and pore properties of the parent coal particles, and the primary fragmentation during devolatilization.关键词
