The influence of furnace bed pressure drop on the performance of circulating fluidized bed coal-fired boiler was analyzed,and the design theory and method were proposed for the energy saving circulating fluidized bed boiler with low bed pressure drop on the basis of fluidization reconstruction.

There is a problem of pressure drop rising during coker gasoline hydrorefining in the catalyst beds of unit1-B of SINOPEC Guangzhou Company.

The influence of the stirrer speed and the blade shape on the fluidization in the stirred gas-solid fluidized beds was experimentally studied by examining the relationship between the pressure drop and superficial gas velocity.

The pressure drop and two dimensional temperature profiles of a new hollow cylindrical vinyl acetate synthesis catalyst were measured in packed bed, and active ingredients were maldistributed on the inner and outside surface of this hollow cylinder.

The plots of bed pressure drop of fluidized bed were established and then the effects of feed rate,temperature of entering drying air,flow rate of entering drying air,and diameter of inert particles on the heat transfer performance of the(drier) were studied in detail.

In an aerated spouted bed with a draft tube made of polymethylmethacrylate with internal diameter 92 mm, the glass beads used as experimental material, under the different aerating velocity, aerating position, punching rate, the bed pressure drop and particles down moving rate in the annulus were studied.

With the floater of power plant as the bed material to conduet cold state modelling experiment under the steady operation condition of furnace,the systematic study included:the relation of fluidized air velocity,bed pressure drop and height of bed material of bottom ash cooler;the effects of ash inl.
