Abstract To address biomass particle aggregation, bridging, pipe blockage and feeding fluctuation in bins and pipes, a novel double-bin pneumatic feeder (DBPF) based on double gases has been proposed to achieve continuous and stable feed for pyrolysis equipment. Taking larch particles as test materials, the feeding characteristics, including feeding rate, solid-gas ratio and pressured drop of the DBPF are investigated with different feeding parameters. The results are concluded as follows: (a) feeding characteristics are dependent on and limited by feeding parameters; (b) feeding mechanisms of injection gas and disturbance gas are essentially different; (c) disturbance gas enhances feeding stability and continuity; (d) injection gas and disturbance gas are complementary, which together promote the feed and stability; and (e) a model for feeding rate is established with accuracy of ±15%. The present study is expected to provide some useful reference for pneumatic feeder.

一种新型生物质颗粒双仓气动给料机的给料特性

摘要 针对生物质颗粒在料仓和管道中聚集、架桥、堵塞和进料波动的问题，提出了一种基于双气体的新型双料仓气动进料器（DBPF），以实现热解设备连续稳定进料。以落叶松颗粒为试验材料，研究了不同进料参数下DBPF的进料特性，包括进料速率、固气比和压降。结果总结如下： (a) 饲养特性取决于饲养参数并受其限制；(b)注入气和扰动气的供给机制有本质的不同；(c) 扰动气体增强进料稳定性和连续性；(d)注入气和扰动气互补，共同促进进料和稳定性；(e) 建立喂料率模型，精度为±15%。本研究有望为气动喂料机提供一些有益的参考。
