Study on Calculation Method of Pressure Loss of Woodchips Transporting Equipment in Long Distance with High Pressure
摘要
Abstract
In order to improve the accuracy of long distance pressure feed computation of woodchips,a new equivalent length method popularized internationally was adopted in this paper.The algorithm covers the sections of horizontal pipe and vertical pipe as well as all the elbow pressure loss.Based on conservation of mass of continuity equation,and state equation of isothermal process,the absolute static pressure difference between starting of pipeline（Point B under the feeder） and end of the pipeline（discharge point） can be acquired,which is the pressure loss of BC segment.And the power loss of the whole system is the sum of BC segment pressure loss and other pressure loss.关键词
