本文主要介绍了低压过热蒸汽和中压饱和蒸汽对蒸汽煅烧炉换热的不同效果。指出提高蒸汽的温度就能提高换热效果这一错误概念，蒸汽的换热效果不仅与其温度有关，还与其压力有很大的关系。 This paper mainly introduces the different effects of low pressure superheated steam and medium pressure saturated steam on heat exchange in steam calciner. Pointed out that the increase of steam temperature can increase the heat transfer effect of the wrong concept, the heat transfer effect of steam not only with its temperature, but also with its pressure has a great relationship.
