摘　　要：锅炉水的二氧化硅含量对锅炉传热面结垢至关重要。二氧化硅可以与足够浓度的蒸汽一起挥发,沉积在锅炉中导致锅炉表面结垢。提出了一个简单的关联来预测二氧化硅在锅炉蒸汽中的溶解度测定误差技术。该相关性简单易用,可不进行任何实验测量而快速检测出锅炉炉水中二氧化硅的溶解度,作为降低锅炉炉水二氧化硅含量的函数具有巨大的实用价值。The silica content of boiler water is very important for the scaling of boiler heat transfer surface.Silicon dioxide can volatilize with enough concentration of steam and deposit in the boiler,resulting in scaling on the boiler surface.A simple correlation technique is proposed to predict the measurement error of silica solubility in boiler steam.The correlation is simple and easy to use,which can quickly detect the solubility of silica in boiler water without any experimental measurement.As a function of reducing the silica content in boiler water,it has great practical value.
