本文利用苏联所介绍的热计算方法构成图线,在计算船用燃油锅炉时便于方案论证、初步设计及估算辐射受热面积。比标准方法(苏联和联合标准)简便得多,而且对已有的一些锅炉进行验算,其结果比较接近,误差不大。 In this paper, the thermal calculation method introduced by the Soviet Union is used to form a graph, which is convenient for scheme demonstration and preliminary design and estimation of the radiation heating area in the calculation of a marine oil-fired boiler. More than the standard method (the Soviet Union and the joint standard) is much more convenient, and some of the existing boiler checking, the results are relatively close, the error is small.
