摘　　要：在综述火电厂机炉蒸汽初参数匹配规范现状和实践的基础上,讨论了机炉压降与主蒸汽管道压降两者涵义的差异,并借助简化的主蒸汽管道阻力计算方程,提出了与机炉压降相匹配的主蒸汽管道管径尺寸或流速核算准则.On the Basis of the status quo of the matching norm and practices for power plant boiler-turbine main steam parameters, this paper discusses the definition difference between the pressure drop of boiler-turbine and the pressure drop of steam-generator lead line, putting forward the check criteria for main steam piping diameter size which is well-matched to the boiler-turbine pressure difference with the aid of simplified equation of main steam piping resistence.
