摘　　要：在系统分析NKSV分解炉气固两相运动规律及其性能特点的基础上,指出了NKSV分解炉的不足之处,提出了改进方案。结果表明:改进后的分解炉在物料分散、煤粉的燃烧环境、物料停留时间等方面均有较大改善,克服了NKSV分解炉存在的旋流强度过大的缺陷,缩口的二次喷腾作用得到了明显的体现,为分解炉的优化设计提供了指导。Based on the analyses of motion mechanism and performance of gas-solid phases in NKSV calciner, the disadvantages of NKSV calciner were presented, and the methods of modifying design are put forward. Results from the test indicated that the improved calciners are perfect reactors for the distribution and retention time of powder and the combustion of pulverized coal. The stronger vortex effect is weakened, and the spout effect in mixture room is enhanced. This builds the foundation for operation and design.
