Fluidized Bed Combustion - an overview | ScienceDirect Topics

Bruce G. Miller, in Coal Energy Systems, 2005 Fluidized-Bed Combustion. Fluidized-bed combustion is not an SO 2 control technology per se; however, this combustion technology does offer the capability to control SO 2 emissions during the combustion process rather than after combustion where FGD systems need to be installed. Fluidized-bed combustion and the role of sorbents in controlling SO 2

Fluidized bed combustion boilers - energypurse.com

The fluidized bed boiler is gaining in popularity and has overtaken the grate-fired boiler in biofuel power generation applications. The principle is very simple: air is blown through a bed of sand and fuel particles at a velocity that is sufficient to suspend the particles on the airstream but not able to lift them permanently out of the bed, that is, 1–3 m s −1 at 800–900 °C.

Fluidized bed combustion - Wikipedia

Fluidized Bed Combustion. Atmospheric fluidized beds use limestone or dolomite to capture sulfur released by the combustion of coal. Jets of air suspend the mixture of sorbent and burning coal during combustion, converting the mixture into a suspension of red-hot particles that flow like a fluid. These boilers operate at atmospheric pressure.
