沸腾炉旋风燃尽室的冷态及热态试验研究

Cold and Hot-state Experimental Study of the Burn-out Chamber of a Fluidized Bed Boiler

对沸腾炉旋风燃尽室进行了冷态模型试验和热态燃烧试验。在冷态试验中,对旋风燃尽室的空气动力场特性以及颗粒运动、分布和分离情况进行了观测。在热态燃烧试验中,测算了锅炉的燃烧效率。试验结果表明:采用旋风燃尽室来提高沸腾炉的燃烧效率是可行的。

A cold-state model test and hot-state combustion test were conducted of the cyclone burnour chamber of a fluidized bed boiler. During the cold-state test investigated and measured were the aerodynamic field characteristics, particle movement, distribution and separation conditiose of the cyclone burn-out chamber. The boiler combustion efficiency was evaluated in the course of the hot-state combustion test. The test results show that it is feasible to enhance the combustion efficiency of fluidized bed boilers through the use of the cyclone burn-out chamber.
