利用出口几何结构改善循环流化床锅炉性能

循环流化床锅炉出口几何结构对炉内气固两相流动特性和传热特性有强烈的影响，称为循环流化床锅炉出口端头效应。试验结果表明，采用合理的出口几何结构，可以增强颗粒的内循环和炉内传热。

The Improvement of Circulating Fluidized Bed Boiler Performance Through the Use of Exit Geometric Structures

The exit geometric structures of a circulating fluidized bed boiler exercise a tremendous influence on its in boiler gas solid dual phase flow behavior and heat transfer characteristics. This is called the exit end effect of a circulating fluidized bed boiler. Test results have shown that the use of a rational exit geometric structure is conducive to the enhancement of particle internal circulation and in boiler heat transfer.
