CFB Boiler

Circulating fluidized bed technology has come a long way over the past 20 years. Starting from hard-to-burn fuels, particularly in the forest products industry, it has become a mainstream combustion technology.

The benefits of CFB technology – such as its multifuel capability and low-emission performance without the need for secondary systems – have made it an increasingly attractive alternative for many other users, too.

The reliance on subcritical steam parameters, however, has limited CFB’s potential in true utility-scale applications, with the largest current designs in the order of 300 MWe and efficiencies between 38-40 per cent.
