Abstract
Pipeline transportation is the best way to send the coal slime to circulating fluid bed boilers. The pressure loss of coal slime in pipeline transportation should be calculated accurately which has close relationship with the system design. In this paper, the influencing factors of coal slime pressure loss in pipe flow at high pressure were investigated at a designed test facility. The experimental results show that pressure loss is directly proportional to flow rate, but inversely proportional to pipe diameter. It is also found that the pressure loss has a complex exponential relationship with volume concentration. Based on the results above, a new calculation model for pressure loss of coal slime was built up. The coefficients in the calculation model were determined from the experimental data by means of nonlinear curve fitting step by step. The validity of this calculation model was verified by the experiments carried out on the large-scale circular pipeline transportation system which has the same parameters with industrial application.
