气化剂流量对棉秆气化性能的影响

棉秆气化可以改变目前棉秆低效高耗的利用现状，气化过程中必须通入一定量的气化剂。通过控制风机转速研究了气化剂流量对棉秆气化性能的影响规律，利用HBG-Ⅰ型户用型生物质气化试验台，针对在不同气化剂流量下的棉秆气化产气情况，采用岛津GCSA型气相色谱仪进行测试分析。结果表明：在固定的气化剂流量下，可燃气成分基本稳定；气化剂流量不宜过高，风机转速为350—450r／min时，能保证可燃气质量。

不同气化剂对等离子体处理油基钻屑气化过程影响的试验研究

为更好地资源化、无害化处理油基钻屑,提高资源利用率,创新性地提出使用等离子体气化熔融处理油基钻屑的方法,该技术采用热解和热脱附双重原理,具有处理彻底、无二次污染、减容率高等优点。在自主开发的撬装式高温等离子体气化熔融处理试验装置上进行了系列研究,以CO_(2)、O_(2)、空气3种气体作为气化剂,通过改变气化剂种类和体积流量,分析其对气化效果的影响,最终确定3种气化剂的最优运行参数分别为CO_(2)体积流量3.6 m^(3)/h,氧气当量比ER 0.2,空气体积流量6.0 m^(3)/h。

Effect of CO Combustion Promoters on Combustion Air Partition in FCC under Nearly Complete Combustion

With CO combustion promoters, the role of combustion air flow rate for concerns of economics and control is important. The combustion air is conceptually divided to three parts: the air consumed by coke burning,the air consumed by CO combustion and the air unreacted. A mathematical model of a fluid catalytic cracking(FCC)unit, which includes a quantitative correlation of CO heterogeneous combustion and the amount of CO combustion promoters, is introduced to investigate the effects of promoters on the three parts of combustion air. The results show that the air consumed by coke burning is almost linear to combustion air flow rate, while the air consumed by CO combustion promoters tends to saturate as combustion air flow rate increases, indicating that higher air flow rate can only be used as a manipulated variable to control the oxygen content for an economic concern.
