THERMAL FATIGUE FAILURE IN BED EVAPORATOR TUBE OF AN AFBC BOILER

the boiler with fresh bed material. From day one, the iron should be monitored, by frequent bed draining and replacing with iron free bed ash. Magnetic drums are used for this purpose. Bed ash bulk density should be below 1400 kg/m3. The bulk density of fresh bed material is generally around 1100 -1200 kg/m3.

Fluidized bed combustion - Wikipedia

Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.
