摘要
一、概述 循环流化床内燃料作循环运动,主床气流速度高,气流与燃料接触强烈。这些特点导致燃料在炉内燃烧强烈,燃烧效率高,燃料充满度高,热负荷大。由于床内气流速度高,颗粒在床内一次停留时间短。中科院热物理所研制的7.
Tests of residence time distribution of particles in circulation f luidized bed have been carried out by spouting magnetic-tracer in the bottom of the bed and detecting by magnetic-concentration gauge in the exit. Making some assumptions a mode is developed based on the experimental dates. The relations between the curve of residence time distribution and parameters such as delay-time, mean particle diameter, gas velocity and fluidized density are well revealed by the mode.
