Membrane walls composed of vertical tubes connected by fins, as shown in Figure , are commonly employed as heattransfer surfaces to remove heat from circulating-fluidized bed (CFB) combustors. The riser reactors are rectangular or square in cross section. The membrane tubes influence the dynamics of

A mathematical model to describe a circulating fluidized-bed combustor is presented. A modified two-phase model which was used in the bubbling fluidized-bed combustor is considered to simulate the dense zone of the bottom section. For the upper section of the bed the momentum and energy-balance equa
The influence of design and operating parameters on minimum upstream bed height required for steady solid circulation across a compartmented gas-fluidized bed has been studied. The partition plate in the compartmented bed is fitted with two pairs of Vvalve and riser with orifices in them. Silica san
