What is a circulating fluidized bed boiler (“CFB”)?
The circulating fluid bed (“CFB”) boiler system is a fully contained state-of-the-art technology for processing solid fuels where fuel is suspended in a mixture of superheated air and sand, collectively called the fluid bed. Reagents like limestone are added, and temperatures are controlled to directly capture the sulfur and reduce formation of Nitrogen Oxides. CFB systems produce less than 1/10th of the emissions of coal fired plants.
