双燃料煤粉流化床复合燃烧锅炉的物质平衡与热量平衡

The Material and Heat Balance of a Dual fuel Pulverized Coal fired Fluidized Bed Multiple Combustion Boiler

本文分析了双燃料煤粉流化床复合燃烧锅炉的物质平衡及热量平衡，得到了炉膛及空气预热器的物质平衡方程、沸腾层及煤粉炉膛的热平衡方程以及炉膛出口过量空气系数、锅炉气体未完全热损失。

An analysis is made of the material and heat balance for a dual fuel pulverized coal fired fluidized bed multiple combustion boiler. Obtained are a material balance equation for the boiler furnace and air heater, a heat balance equation for the fluidized bed and the pulverized coal fired furnace and a calculation formula for furnace outlet excess air faclor, unburned flue gas heat loss and unburned carbon heat loss.
