摘　　要：在计算机仿真、模拟技术如火如荼发展的今天,玻璃熔窑热工理论计算依然有其不可替代的作用。在前人研究工作的基础上,以1000 t/d平板玻璃熔窑为例,结合目前工程实际情况,介绍了熔窑实际烟气生成量计算的新思路;提出了确定烟囱出口烟气流速时需要与环境风速和烟气的流动状态综合考虑,给出了计算步骤;并对烟囱出口内径、烟气流程总阻力损失和烟囱几何高度进行了示范性设计计算。Although the computer simulation technology is popular today,glass furnaces thermotechnical calculation is still significant.On the basis of previous research work,taking 1000 t/d plate glass melting furnace as an example and combining with the current engineering practice,a new way of calculating the actual flue gas production quantity of melting furnace is introduced.It is proposed that the velocity of flue gas at the chimney outlet should be taken into account comprehensively with the ambient wind speed and the flow state of flue gas.The inner diameter of the chimney outlet,the total resistance loss of the flue gas flow and the geometric height of the chimney are calculated.
