Pyroflow circulating fluidized bed (CFB) boilers have been demonstrating an excellent fuel flexibility while simultaneously meeting stringent emission control requirements. The size of these boilers has been gradually increasing for utility applications. As the size of the unit increases more attention is required in the selection and arrangement of the superheater, reheater etc. to ensure very high availability. Right from the initial stage of development of the CFB technology, Ahlstrom Pyropower has recognized the benefits of providing in-furnace evaporative or superheat surface in comparison with other options. As a result Pyroflow boilers have been provided with in-furnace evaporative and/or superheat surface when required. This paper presents the development of different types of in-furnace surfaces, describes the design considerations, addresses the concern on erosion and summarizes the successful operational experience of many Pyroflow units.
