摘　　要：在分析脉动燃烧概念、特点和应用基础上,对Rijke型脉动燃烧器燃用固体燃料时的脉动燃烧特性、传热特性和产物生成特性的试验研究进行总结并分析讨论,可以看出脉动强化了气流与颗粒间的传热、传质,具有燃烧效率高、传热效果好、污染物排放少的优点,是一种高效节能低污染的燃烧方式。最后提出了将脉动燃烧和流化床技术相结合的脉动流化床燃烧技术。Pulsing combustion technology makes use of the intensifying effect of pulsating gas flow on mass and energy transfer between gas and solids as well as among gases. It has the advantage of high combustion efficiency, intensive heat transfer and low pollutant emission. Starting with a discussion concerning the concept of pulsing combustion, its particular features and application, test results obtained with Rijke type pulsing burners are being analyzed in respect to particularities of combustion, heat transfer and formation of reaction products in the case of combusting solid fuels. Pulsation obviously intensifies heat and mass transfer between the gas flow and the solid particles and is therefore distinguished by high combustion efficiency, good heat transfer property and low pollutant emission. In the conclusion pulsing fluidized bed combustion technology is proposed which combines pulsing combustion with fluidized bed technology. Figs 11, tables 2 and refs 35.
