摘　　要：根据多相流流动特性对固相质量流量及流速之间的依赖关系,通过在以气力输送系统为基础的煤粉/生物质/空气三相流分相浓度测量系统实验平台上,对固相质量流量及风速分别进行了标定试验。结合标定结果将固体颗粒质量流量转换成所需的固相体积浓度,最终达到测量系统的测试要求。According to the flow characteristics of muhiphase depends on the solid mass flow rate and flow velocity measurement, through the concentration measurement system experimental platform based on the pneumatic conveying system of pulverized coal/biomass/air three - phase flow split phase, the calibration tests were carried on solid mass flow rate and wind speed separately. Then combined with the cali- bration results, the mass flow of the solid particles was converted into the desired solid volume concentration. Eventually it reached the test requirements of the measuring system.
