Optimization of Bed Material Consumption in a CFBC Boiler

1.6 Bed Material: It can be understood from above theory that the CFBC system works on a continuous fluidized bed of the feed material. Initially, during the boiler light up, the bed is majorly made up of Silica (SiO 2) and Alumina (Al 2 O 3). This bed material is fluidized by means of PA air. The initial light up is done by using Light Diesel Oil.:International Journal of Engineering Research and · 2015:Ashish M Pullekunnel · Manish R Moroliya · Babasaheb AmbedkarCFBC Boiler Initial Firing - YouTubehttps://0:28Nov 23, 2017· You can see fluidized bed material(Sand and Bed ash) in the CFBC boiler.
