NUMERICAL OPTIMIZATION OF AIR FLOW IN THE PLENUM CHAMBER OF AN INDUSTRIAL CFB BOILER
Abstract
The article presents the results of experimental and numerical studies on windboxes operating in a 235MWe Circulating Fluidized Bed (CFB) boiler. The main problems of windbox designs have been identified and a modified internal geometry has been proposed which causes a more uniform flow under the grid and prevents the velocity field from formation of dead zones.
