流化床风帽温度分布及其耐热性的试验研究

Experimental Study of the Temperature Distribution of a Nozzle Button in a Fluidized Bed and Heat Resistance of the Nozzle Button

:在一热态流化床试验台上 ,对热烟气床下点火启动条件下风帽的温度分布进行了试验研究 ,并考察了风帽所用材质的耐热性。鉴于目前流化床锅炉逐步采用床下点火启动方式 。

An experimental study was conducted of the nozzle button temperature distributio n on a fluidized bed test facility under start up conditions with the under be d ignition being carried out with the help of high temperature gases. The heat re s istance of the material used for the nozzle button is also assessed. In view of the increasing use of under bed ignition mode for the start up of fluidized be d boilers the above study is of great significance in providing guidance for p ractical engineering applications.
