In order to clarify the dynamic characteristics of bed temperature of biomass circulating fluidized bed (CFB) boiler, so as to establish a CFB combustion control system which is more suitable for biomass, a dynamic bed temperature model is established by analyzing the biomass combustion process and combustion mechanism. On the basis of the theory of instant burning carbon combustion, the correlation degree of temperature field in the furnace is calculated and analyzed. The results show that, the calculated bed temperature can be controlled basically stable near the filtering value of the actual bed temperature, and the variation trend of the bed temperature is similar to that of the actual filter bed temperature, which verifies the adaptability and effectiveness of the model. The temperature correlation difference of the upper and lower parts of the biomass CFB boiler is related to the oxygen content and the temperature of the furnace. The temperature difference of the left and right sides is greatly affected by the flue gas flow. In the upper part of the furnace, the material concentration and the uneven heating surface arrangement are also important reasons affecting the temperature characteristics.

为明确生物质循环流化床锅炉床温动态特性,建立更加适合生物质的循环流化床燃烧控制系统;通过分析生物质燃烧过程以及燃烧机理,基于即燃碳燃烧理论,建立床温动态模型,并对炉内温度场进行关联度计算分析。结果表明:计算的床温能够基本稳定在实际床温滤波值附近,且床温变化趋势和实际滤波床温相近,验证了模型的适应性和有效性;生物质循环流化床锅炉炉膛上下部的温度关联性差异与含氧量和炉膛温度有关,左右侧温度差异受烟气流量影响较大,在炉膛上部,物料浓度和受热面布置不均也是影响温度特性的重要原因。

为明确生物质循环流化床锅炉床温动态特性,建立更加适合生物质的循环流化床燃烧控制系统;通过分析生物质燃烧过程以及燃烧机理,基于即燃碳燃烧理论,建立床温动态模型,并对炉内温度场进行关联度计算分析。结果表明:计算的床温能够基本稳定在实际床温滤波值附近,且床温变化趋势和实际滤波床温相近,验证了模型的适应性和有效性;生物质循环流化床锅炉炉膛上下部的温度关联性差异与含氧量和炉膛温度有关,左右侧温度差异受烟气流量影响较大,在炉膛上部,物料浓度和受热面布置不均也是影响温度特性的重要原因。

In order to clarify the dynamic characteristics of bed temperature of biomass circulating fluidized bed (CFB) boiler, so as to establish a CFB combustion control system which is more suitable for biomass, a dynamic bed temperature model is established by analyzing the biomass combustion process and combustion mechanism. On the basis of the theory of instant burning carbon combustion, the correlation degree of temperature field in the furnace is calculated and analyzed. The results show that, the calculated bed temperature can be controlled basically stable near the filtering value of the actual bed temperature, and the variation trend of the bed temperature is similar to that of the actual filter bed temperature, which verifies the adaptability and effectiveness of the model. The temperature correlation difference of the upper and lower parts of the biomass CFB boiler is related to the oxygen content and the temperature of the furnace. The temperature difference of the left and right sides is greatly affected by the flue gas flow. In the upper part of the furnace, the material concentration and the uneven heating surface arrangement are also important reasons affecting the temperature characteristics.
