Biomass gasification in a circulating fluidized bed
Abstract This paper presents the results from biomass gasification tests in a pilot-scale (6.5-m tall × 0.1-m diameter) air-blown circulating fluidized bed gasifier, and compares them with model… Expand
The yield stress of fibre suspensions
- C. Bennington, R. Kerekes, J. Grace
- Materials Science
- 1 October 1990
Yield stresses were determined for commercial wood pulp suspensions and synthetic fibre suspensions of low and medium mass concentration. The yield stresses measured represent interfibre failure of… Expand
Contacting modes and behaviour classification of gas—solid and other two-phase suspensions
- J. Grace
- Materials Science
- 1 June 1986
An attempt is made to extend schemes for classifying the behaviour of gas—solid contacting modes and other two-phase systems. The regime diagram approach of Reh (1971) is modified and extended to… Expand
A State-of-the-Art Review of Gas-Solid Turbulent Fluidization
- H. Bi, N. Ellis, I. A. Abba, J. Grace
- Chemistry
- 1 November 2000
Abstract Turbulent fluidization has only been widely recognized as a distinct flow regime for the past two decades, even though it is commonly utilized in industrial fluidized-bed reactors due to… Expand
Effect of bubble interaction on interphase mass transfer in gas fluidized beds
Abstract A non-interfering technique has been used to measure the concentration of ozone in pairs of bubbles injected into a bed of inactive 390 μm glass beads fluidized by ozone-free air. The… Expand
Equilibrium modeling of gasification: a free energy minimization approach and its application to a circulating fluidized bed coal gasifier
- X. Li, J. Grace, A. Watkinson, C. Lim, A. Ergüdenler
- Chemistry
- 2001
Abstract A non-stoichiometric equilibrium model based on free energy minimization is developed to predict the performance of gasifiers. The model considers five elements and 44 species in both the… Expand
