摘要：The s.udy of s.irling jet combus.or for biomas. coal co-firing is.of great interes. for energy indus.ry. The biomas. co-firing can s.rve as.a NOx reduction method as.well as.the better us. of renewable energy s.urce. Large eddy s.mulation (LEs. and RANs.modelling have been performed with two different burner des.gns. Us.ally pulverized coal-biomas. mixture enters.the furnace along with primary air through primary pipe, and the s.condary pipe provides.neces.ary air and mixing for combus.ion. The improved model has.three pas.ages.including primary, s.condary and middle pas.age for s.irling. The s.mulations.on two geometries.have been compared, and the aim is.to des.gn a better and improved burner model for better pre-combus.ion mixing in the biomas. co- fired furnace. The res.lts.from two-way and three-way geometry have been compared with each other as.well as.with the res.lts.from the furnace model us.d by Apte and Mahes. [8].

摘要：这是一种新型的综合测试系统，它克服了抽油机各部件效率和总效率不能直接测试的缺陷，通过对压力、负荷、位移、功率、扭矩、转速等参数的自动检测及数据处理；实现了对抽油机系统的综合效率的测量。该系统经长庆油田现场试验，各项技术指标达到设计要求。
