The circulating fluidized bed (CFB) is a clean process with the ability to achieve lower emission of pollutants. By using this technology, up to 95% of pollutants can be absorbed before being emitted to the atmosphere. At the same time, the advantages of this technology outweigh the limitations, which make it favourable. However, the development of this technology is still in its early stages. With further R&D, this technology is predicted to bring numerous benefits to our society.
