Considering lower combustion efficiency and serious pollution of the fly ash from the ordinary FBC (Fluidized Bed Combustor), this paper reports a new method of fluidized bed combustion(Pulsing Fluidized Bed Combustion). Authors have carried out a series of expeirmental researches on the flow dynamics and heat transfer behaviors in the cold model of the pulsing fluidized bed combustor. Experimental results show that the pulsing fluidized bed has following advantages which the ordinary fluidized bed does not possess: (1) minimum fluidizing velocity is lower than that of ordinary F.B. (2) pressure-drop at fluidization stage is lower than that of conventional F.B. (3) the quantity of particle etutriated is less than that of conventional F.B. (4) heat transfer coefficient between the bed materials and single particle is about 10%higher than that of the conventional F.B. We think that perhaps pulsing fluidized bed combustion is an effective way to increase the combustion efficiency and prevent the pollution of fly ash.

针对流化床的燃烧效率低和飞灰污染严重特点,本文提出了一种新型的流化床燃烧方法:脉冲流化床燃烧。作者对脉冲流化床的各种冷态特性进行了一系列较为系统的研究,结果表明,采用脉冲流化床以后,出现了一系列常规流化床所不具备的优点:临界流化速度小,床层阻力下降,扬析量减少床内颗粒的传热系数提高。研究结果显示,采用脉冲流化床燃烧方式有可能提高燃烧效率,减少飞灰污染和降低风机能耗。

Because lower combustion efficiency and serious pollution of fly ash hamper the further application of the fluidized bed combustion, authors present a newmethod of the fluidized bed combustion-the pulsating fluidized bed combustion.Some researches on the mechanism of the pulsating fluidized bed combustion are introduced. It shows that the pulsating fluidized bed combustion is a valid way to increase the combustion efficiency and prevent the pollution of fly ash.
