【摘要】 把国产５０ＭＷ燃贫煤锅炉的炉膛看作一个瑞克型燃烧室，分析了炉膛负压脉动的成因。根据脉动燃烧的研究成果，计算了炉膛烟气负压脉动的驱动力，并应用气力输运理论对送风机电压波动驱动炉膛负压脉动作了定量分析。图３参４更多还原

【Abstract】 In this paper, the furnace of 50MW Barren Coal Boiler, made in China, is regarded as Rijke Pulse Combustor and the causes of negative pressure pulsation in it are analyzed. According to the theory of pulsation combustion, the driving forces that cause negative pressure pulsation are studied. Based on the theory of pneumatic transport, how the fluctuation of air pressure of the fan influences the pulsation of negative pressure in furnace is quantitatively analyzed. Fig 3 and refs 4.更多还原
