摘要
在自行研制的循环流化床冷态试验台上对哈锅引进 4 40t/hCFB锅炉关键部件特性及炉内气固流动特性进行了试验研究 ,测定了大直径钟罩式风帽及布风板的阻力特性 ,发现了安装方向对风帽的磨损规律 ,对分叉管U型回料阀和旋风分离器进行了模拟试验 ,对双炉膛结构对流动的影响进行了观察 ,认识了哈锅CFB锅炉的多方面特性。认为哈锅引进型CFB锅炉有许多创新之处 ,应进行仔细地研究 ;
Some technical features of the key components of H G -440/13.7-L.PM4 CFBB were investigated on a self-made cold CFB experimental set to master the introduced-technology. The resistance coefficient of large diame ter bell type bubbling nozzle was measured and some wear rule was found. Experim ent of cyclone separator and U-valve was carried out and the twin furnace influ ene on gas-solid flue feature was observed. Several innovations are carried out on this boiler and we should carry out further invetigation.
