CFB Boiler

Calderys has been delivering results to Circulating Fluidised Bed (CFB) boiler operators for decades, with projects all over the world (for both cooled and uncooled technologies) including the Nordic countries, Poland, Germany, India, and China. Discover some samples of our refractory recommendations for CFB boilers for all feedstock types: waste, biomass, and coal.
