摘　　要：为了推动高热燃烧剂在非爆炸式销毁应用领域的深入发展,采用全局优化、接触式测温、红外热像、热重-傅里叶红外联用等技术手段,开展了硼铝基火焰射流型燃烧剂的热解及燃烧性能研究。结果表明,硼的加入促进了配方中硝酸钡的分解,且随着硼质量分数的增加,燃烧温度显著上升,当硼的质量分数不小于5%时,硼铝基射流型燃烧剂的燃烧最高温度高于硼起始氧化质量增加温度400℃。获得了硼铝基射流型燃烧剂较优配方,铝、硼、三氧化二铁、硝酸钡的质量分数分别为25%、5%、45%、25%。当药量由1 g增至10 g时,燃烧最高温度增加613.8℃,射流型火焰面积增加1.35倍。此外,热分解符合自催化反应模型,反应级数为1.0738,自催化指数为0.0888,活化能为257.31 kJ/mol,指前因子为1.55×10^(11)s^(-1)。To promote the development of high-heat combustion agents for non-explosive disposal applications,the use of global optimization techniques has enabled the creation of more effective and efficient formulations.This advancement is crucial for applications that require elevated temperatures for processing.The integration of contact temperature measurement and infrared thermography offers a thorough analysis of combustion agent performance.Additionally,the application of Thermogravimetric-Fourier Transform Infrared Spectroscopy and other advanced techniques has enhanced the study of thermal decomposition and kinetics of boron-aluminum based flame jet-type propellants.These studies have provided valuable insights into the decomposition process by determining specific reaction orders,autocatalytic indices,activation energies,and pre-exponential factors.The results indicate that adding boron enhances the decomposition of Ba(NO_(3))_(2)in the formulation.Furthermore,as the boron content increases,the combustion temperature rises significantly,underscoring the critical role of boron in high-heat combustion agent formulations.When the B content is at least 5%,the maximum combustion temperature of the boron-aluminum based flame jet-type propellants exceeds the initial oxidation weight gain temperature of B by 400℃.As the Fe 2 O 3 content increases,the maximum combustion temperature initially decreases before rising,suggesting complex interactions among the components of the combustion agent.An optimal formulation for boron-aluminum based flame jet-type propellants has been developed,comprising 25%aluminum(Al),5%boron(B),45%iron(III)oxide(Fe_(2)O_(3)),and 25%barium nitrate[Ba(NO_(3))_(2)].As the charge increases from 1 g to 10 g,the maximum combustion temperature rises by 613.8℃,and the flame jet area expands by 1.35 times.This demonstrates the scalability of the formulation and its potential for diverse applications.Furthermore,the thermal decomposition follows an autocatalytic reaction model,characterized by a reactio
