工业锅壳煤粉锅炉因其诸多优点,得到广泛应用.炉膛出口烟气温度可以为锅炉的设计提供重要参考.为了优化锅炉设计,分析了现有的烟温计算方法-73标准和《燃油燃气锅炉》简化算法.并根据能量衡算及辐射、对流传热方程建立了一维稳态传热数学模型,提出了具体的计算方法,通过10 t/h示范锅炉的验证,与已有的2种计算方法进行对比,表明该方法计算简便、准确.但在实际运行中需要考虑水侧热阻的影响.%Industrial shell type pulverized-coal boiler is widely used thanks to its lots of advantages. Gas temperature at furnace outlet can provide reference for the design of boiler. In order to optimize the design, analyze status gas temperature calculation methods, which are 73 standard and 《oil-fired and gas-fired boiler》simplified algorithm. The one-dimensional steady-state heat-transfer model is established based on the calculation of energy balance, radiative and convective heat transfer equation. Put forward specific calculation method, which is compared with above two methods,the practical production of 10 t/h industrial shell type pulverized-coal boiler proves that the results simply got by this method is accurate. The only one issue need to be concerned is that the influence of thermal resistance.
