Method for calculating heat supply steam pipeline production and acceptance evaluation thermal indexes

The invention relates to a method for calculating heat supply steam pipeline production and acceptance evaluation thermal indexes. The method is used for a thermal power plant. After a heat supply steam pipeline is put into production, it is required to carry out construction acceptance and evaluation on the steam pipeline. At present, in relevant specifications and data, the evaluation and the acceptance of a heat supply pipeline network mainly relate to requirements for the insulation thickness of the pipeline or a support of the pipeline, but less relate to thermal indexes such as pressuredrop, temperature drop and heat loss. In the present invention, the heat supply steam pipeline production and acceptance evaluation thermal indexes include the temperature drop of the heat supply steam pipeline, the pressure drop of the heat supply steam pipeline, the leakage rate of the heat supply steam pipeline and the heat loss rate of the heat supply steam pipeline, and the method for calculating the temperature drop
