摘要：目前滴管炉系统以其体积较小、操作便利以及模拟性能较好等优点被广泛应用于煤的热解、气化与燃烧等热模试验研究,以深入了解煤样品的相关特性及反应动力学机理,并为实际工业生产过程的优化提供试验基础和理论指导。综述了近年来国内外将滴管炉应用于煤粉热模试验的研究进展,目前应用的滴管炉主要可分为3类:气化炉型常压滴管炉、加压滴管炉及两段式滴管炉,各类型滴管炉以其结构、功能的不同而被应用于不同试验研究。基于对3类滴管炉应用现状的分析和炉内颗粒沉降仿真模拟,进一步剖析目前滴管炉存在的主要问题,并提出了3点改进开发方向:扩展可模拟条件、加强全面温度监控、维持颗粒沉降稳定,以期使滴管炉系统能在未来相关研究中发挥更大作用。
At present,the drop tube furnace system is widely used in the experimental research of pyrolysis,gasification and combustion process of coal particles with its advantages of small size,convenient operation and good simulation performance,so as to deeply understand the relevant characteristics and reaction kinetic mechanism of the coal samples,and provide experimental basis and theoretical guidance for the optimization of the actual industrial production process.The research progress of applying drop tube furnace to hot model experiments of pulverized coal was reviewed in recent years.The drop tube furnaces used now can be mainly divided into three categories:Gasifier type atmospheric drop tube furnaces,pressurized drop tube furnaces and two-stage drop tube furnaces.Various types of drop tube furnaces are used in different experimental studies for their different structures and functions.Based on the analysis of these three types of drop tube furnaces application status and the simulation of particle settlement inside the furnace,the writer further analyzes the problems existing in the drop tube furnaces at present.Finally,three improvement directions are put forward:expanding the simulation capability,strengthening comprehensive temperature monitoring and maintaining stable particle sedimentation,so that the drop tube furnace system can play a greater role in future research.
