流化移动叠置式冷渣器是针对流化床锅炉的高温出渣及其热损失而开发的一种新型冷渣装置。在冷态实验台上对流化移动叠置式的流动特性和传热特性进行了试验。一台设计冷渣量为１．５ｔ/ｈ的冷渣器的运行表明,其能够把０~１３ ｍｍ的９００℃热渣在较低的风渣比下冷却到２５０℃以下,同时经渣换热的空气可作为锅炉的二次风以回收热量。
Fluidized moving stack type slag cooler is a new type of slag cooler developed for high temperature slag discharge and heat loss of fluidized bed boilers. The flow and heat transfer characteristics of the fluidized-displacement stack were tested on a cold bench. The operation of a slag cooler with a design capacity of 1.5 t / h showed that it can cool the 0 ~ 13 mm 900 ℃ hot slag to below 250 ℃ at a lower slag ratio, Hot air can be used as a secondary air to recover heat.
