Fluidized Bed Combustors for Biomass Boilers - ASME

Aug 30 2012 · Boiler engineers can choose between two main types of fluidized-bed boilersbubbling fluidized bed (BFB) and circulating fluidized bed (CFB). In BFB boilers the velocity of the combustion air is low enough that the fluidized particles remain in the lower furnace; in a

Fluidized Bed Furnace - an overview | ScienceDirect Topics

Fig. 10.8 shows a CFB boiler furnace. It differs from other biomass boiler types with regard to the solids separator which is typically a cyclone (Kwauk and Li 1999).The cyclone captures circulating bed material and unburned fuel particles and returns them to the lower part of the furnace through a loop seal (Lackermeier and Werther 2002).After the cyclone the flue gases flow through a ...

Troubleshooting a Circulator Pump | DoItYourself.com

Aug 23 2018 · A boiler's circulator pump is used to remove hot water from the boiler and then pass it into heating devices such as the radiator or a convection pipe system. The power of the pump is enough to cause the water to travel right back up to the boiler from the pipework. Using a circulation pump is a great way of keeping water traveling throughout the system.
