40.5MVA密闭电石炉热平衡计算及能量损失分析

摘要

为提高电石生产效益,根据密闭电石炉主要工艺参数及生产技术指标,对40.5MVA密闭电石炉进行原料、支出物成分进行分析以及对C、CaO、CaCO3、水分、挥发分、SiO2等物料的平衡计算,确定物料平衡表和热平衡表,分析了能量损失的症结所在,提出加强能耗管理、实现生产优化控制以及节能降耗的建议.%In order to enhance the production profit of calcium carbide, according to the main process parameters and technical indicators of closed calcium carbide furnace,it analyzed the raw material and expenditure composition and the C, CaO, CaCO3, moisture, volatilization, SiO2 material balance calculation of 40.5 MVA closed calcium carbide furnace, determined mass balance table and heat balance table,from which to draw the crux of energy loss. Then it gave advice on strengthening energy management, implementing production optimization control, and energy saving.
