One of these is the fluidized bed boiler. This type of combustion system is capable of burning a much wider range of fuels than a PC plant. It operates at a lower temperature, making the production of nitrogen oxide less of a problem, and it can also incorporate sulfur capture within the combustion chamber, leading in principle at least to easier emission control.

Fluidized Bed Boiler - an overview | ScienceDirect Topics

Due to the bed material inside the boiler, fluidized-bed boilers have high heat transfer coefficients, utilize the entire boiler volume, have a uniform temperature distribution and have a low stable combustion temperature. Fluidized beds are capable of burning very wet fuels and fuel particles of sizes up to 80 mm (van Loo and Koppejan, 2006

The two main types of fluidized bed combustion are: the bubbling fluidized bed boiler (BFB) and the CFB boiler. The BFB has a lower own energy consumption and a lower unit price up to about 100300 MWth. The CFB has a better environmental performance. Typically the BFB is used in applications of less than 100 MWth and the CFB from 50 MWel.
