仓式泵高浓度输送煤粉技术

High Density Conveying of Pulverized Coal by Bin Pump

采用新研制的仓式泵实现了大口径管道远距离高浓度输送煤粉。投产半年，该装置运行平稳可靠，技术经济指标良好。该装置的输送能力为４０ｔ／ｈ，平均输送浓度２０ｋｇ／ｍ３，调节该泵各支气管路气体流量的分配比例后，平均输送浓度可以达到４０ｋｇ／ｍ３以上。

High density conveying of pulverized coal over a long distance through big diameter pipe can be realized by using a newly developed bin pump. After half year operation, the equipment proved steady and reliable, and its technical indexes are good. The conveying capacity is 40 t/h and average conveying density is 20 kg/m 3. The average conveying density can be over 40 kg/m 3 by adjusting the gas flows in each branch.
