Bed types can be coarsely classified by their flow behavior, including: • Stationary or Particulate fluidized bed is the classical approach where the gas at low velocities is used and fluidization of the solids is relatively stationary, with some fine particles being entrained. • In Bubbling fluidized (also called Aggregative fluidized bed), the velocities of the fluid is high, thus forming of two separate phases – continuous phase (dense or emulsion phase) and a discontin… WebThe prototype is operated as a circulating fluidized bed: the inner tube of the heat exchanger is a fluidized bed riser, the receiver works as a gas–solid separator, the outer tube (annulus) of the heat exchanger is an overflow standpipe and a buffer tank (reservoir) connects the annulus to the riser, closing the loop. ...
Web(c) Fast Fluidized Bed (Circulating Fluidized Bed): The air velocity in circulating bed combustion is between 4 — 10 m/s. In circulating bed the solid particles elutriated with are return back to the bed at sufficiently high rate. The bed column is divided into two regions. WebThe phenomenon of erosion wear and high temperature corrosion will lead to thinning of tube wall, and serious tube burst will occur after long operation in circulating fluidized bed boiler. To obtain the effect on tubes by erosion wear and ammonia gas high temperature corrosion, a high-temperature gas–solid erosion wear test facility was used ...
