摘要

摘要:
针对粉末燃料可靠流化和定量可调输送问题，开展基于活塞驱动气体流化输运的粉末供应系统特性研究。通过试验研究，开展不同活塞驱动力、流化气压强、粉末出口喉径等参数对粉末流化输运特性的影响研究。研究表明：该系统在所设工况下能够实现稳定送粉；在指定范围内活塞驱动力存在临界值。活塞驱动力小于临界值时，粉末质量流量随驱动力增大而逐步增大。当超过临界值时，可实现活塞驱动力与粉末流化输运的解耦，粉末流量与出粉口喉道面积成线性关系；驱动力增加过程中流化气流量会增加然后迅速减小，当驱动力达到上限时粉末输送的固气比达到最大；单独提高流化气压强使得固气比大幅降低，不利于气源的有效利用。

Abstract:
In view of the problem of reliable fluidization and quantitative adjustable transportation of powder fuel, the characteristics of powdered supply system based on piston-driven gas fluidization and transportation were studied. The influences of different piston driving forces, fluidization pressures and diameters of powder outlet throat on the fluidized transport characteristics of powder were analyzed experimentally. Experimental results showed that the system can stably feed powder under the set working conditions; there existed a critical value of piston driving force within the specified range. When the piston driving force was less than the critical value, the powder mass flow rate increased with the increase of piston driving force. When it exceeded the critical value, the piston driving force can be decoupled from the powder fluidization transport, and the powder flow rate had a linear relationship with the throat area of the powder out-let; the flow rate of fluidized gas increased and then decreased rapidly during the increase of driving force, and the solid-gas ratio of powder transportation was the maximum when the piston driving force reached the upper limit; increasing the fluidization pressure made the solid-gas ratio greatly reduce, which was not conducive to the effective utilization of gas source.
