An industrial biomass boiler of 200 kW thermal power is analyzed by computational and experimental methods. Gas composition and temperature within the furnace and in the downstream heat exchanger are measured. Combustion, flow and heat transfer processes within the furnace, exhaust tract as well as the forced convection on the water side of the heat exchanger are computationally investigated by the finite volume method‐based computational fluid dynamics procedures. The predictions are compared with the experiments. A satisfactory overall agreement between the predicted and measured temperatures is observed with an average deviation about 5 %. For oxygen mole fractions a fair agreement is found that shows deviations within the range of 10–20 %. For carbon monoxide, calculations exhibit a stronger underprediction.

工业生物质炉的计算和实验研究

通过计算和实验方法分析了200 kW火力的工业生物质锅炉。测量炉内和下游热交换器中的气体成分和温度。通过基于有限体积方法的计算流体动力学程序，对炉内，燃烧室，排气管中的燃烧，流动和传热过程以及热交换器水侧的强制对流进行了计算研究。将预测结果与实验进行比较。观察到的预测温度和测量温度之间的总体满意程度令人满意，平均偏差约为5％。对于氧气摩尔分数，可以找到一个公平的协议，该协议的偏差在10％至20％的范围内。对于一氧化碳，计算显示出较强的预测不足。
