Effect of coal particle size distribution, volume fraction

2004-3-15  The effect of the particle size distribution on viscosity was investigated for each coal using three different coal samples with the d 50 particle size of 19, 35 and 50 ΞΌm. The results of apparent viscosity measurements, at a shear rate of 100 rpm, are given in Table 3 .

Optimization of particle size distribution in circulating

2019-6-15  Among the factors affecting the performance of the CFB boiler, the particle size distribution (PSD) of coal gangue feed was found to be the most significant. This has been reflected by that only a slight variation in the average diameter of coal feed can impact the stability of both the crush system and CFB system significantly [ 9,10 ].
