  • integrated drying and incineration of wet sewage sludge in combined bubbling and Circulating Fluidized Bed units
    Waste Management, 2014
    Co-Authors: Shiyuan Li, Yunyu Li, Qinggang Lu
    Abstract:

    An original integrated drying and incineration technique is proposed to dispose of sewage sludge with moisture content of about 80% in a Circulating Fluidized Bed. This system combines a bubbling Fluidized Bed dryer with a Circulating Fluidized Bed incinerator. After drying, sewage sludge with moisture less than 20% is transported directly and continuously from the Fluidized Bed dryer into a Circulating Fluidized Bed incinerator. Pilot plant results showed that integrated drying and incineration is feasible in a unique single system. A 100 t/d Sewage Sludge Incineration Demonstration Project was constructed at the Qige sewage treatment plant in Hangzhou City in China. The operational performance showed that the main operation results conformed to the design values, from which it can be concluded that the scale-up of this technique is deemed both feasible and successful.

  • overall pressure balance and system stability in a liquid solid Circulating Fluidized Bed
    Chemical Engineering Journal, 2000
    Co-Authors: Ying Zheng
    Abstract:

    Abstract A pressure balance analysis has been carried out, along with a dimensionless empirical correlation for the solids holdup in the riser and a semi-empirical equation for the pressure drop across the non-mechanical control valve derived in this work, to successfully predict the stable operating conditions and explain the origin of the unstable operation phenomena of the liquid–solid Circulating Fluidized Bed. The effects of the total and auxiliary liquid velocity, the solids inventory and the unit geometry on the stable operation range are discussed. Furthermore, this work also reveals the importance of unit structure in improving the performance of the liquid–solid Circulating Fluidized Bed systems.

  • A method for estimating the solids circulation rate in a closed-loop Circulating Fluidized Bed
    Powder Technology, 2001
    Co-Authors: Shantanu Roy, A. Kemoun, Muthanna H. Al-dahhan, Milorad P. Dudukovic
    Abstract:

    Abstract We propose a simple method for accurately estimating the solids circulation rate in a closed-loop liquid–solid Circulating Fluidized Bed. The technique is based on the use of radioactive isotopes for estimating the solids velocity and volume fraction distribution in a chosen section of the Circulating Fluidized Bed loop. The method is demonstrated for a liquid–solid Circulating Fluidized Bed, and is readily applicable in other systems such as gas–solids Circulating Fluidized Beds or closed-loop pneumatic and hydraulic transport lines. With minor modifications, the method may be used for industrial systems as well.

  • effect of solid circulation rate on coating efficiency and agglomeration in Circulating Fluidized Bed type coater
    Powder Technology, 2003
    Co-Authors: Hiroyuki Kage, Hironao Ogura, Ryusuke Hattanda, Tao Zhou, Yoshizo Matsuno
    Abstract:

    Circulating Fluidized Bed was proposed to be used as a coater, and coating experiments of glass beads with silica powder were performed in a Circulating Fluidized Bed. Glass beads and silica powder were chosen as model particles, because their shape was almost spherical. The respective effects of gas flow rates supplied from a distributor and from an air nozzle for solid circulation, feed rate of powder suspension and particle content in the Bed on coating efficiency and agglomeration are mainly discussed. Coating efficiency in Circulating Fluidized Bed coater was correlated well with solid circulation time rather than with gas flow rates or solid circulation rate, while the agglomeration among core particles was mainly governed by solid circulation rate.

  • powder coating efficiency of small particles and their agglomeration in Circulating Fluidized Bed
    Korean Journal of Chemical Engineering, 1999
    Co-Authors: Hiroyuki Kage, Mitsunaga Dohzaki, Hironao Ogura, Yoshizo Matsuno
    Abstract:

    The coating efficiency of fluidizing small particles and their agglomeration were investigated to evaluate the possibility of powder coating by the use of a Circulating Fluidized Bed. Glass beads, whose mean diameter was 43 Μm, and silica powder of 1 Μm were used as a core and a coating material. Polyvinyl alcohol was used as a binder and its solution was supplied together with silica powder from a spray nozzle equipped in the Circulating Fluidized Bed. Glass beads of 43 Μm, which had been impossible to coat in a conventional Fluidized Bed coater, were successfully coated with silica powder in a Circulating Fluidized Bed, and agglomeration among core particles was prevented. From this result, it was confirmed that a Circulating Fluidized Bed performs excellently as a coater, especially for fine core particles, so a Circulating Fluidized Bed coater has bright prospects for particle coating.
