本文提出了循环流化床锅炉炉膛的轴向压力及固体浓度分布的计算式。当给出表观气速、循环固体流率以及颗粒性质时，可准确地预测炉膛压降与轴向固体浓度分布，为炉膛设计提供了计算依据。
This paper presents the calculation formula of axial pressure and solid concentration distribution in the hearth of a circulating fluidized bed boiler. Accurately predicting furnace pressure drop and axial solid concentration distribution when superficial gas velocity, circulating solids flow rate and particle properties are given provides the basis for the design of the furnace.
