Update of operating experience of B and W IR-CFB coal-fired boilers
This paper updates the operating experience of two Babcock and Wilcox (B and W) coal-fired, internal recirculation circulating fluidized-bed (IR-CFB) boilers. The first boiler is located at Southern Illinois University (SIU) in Carbondale, Illinois, USA, and is designed for 35 MW{sub th} output for cogeneration application, utilizing high sulfur, low ash Illinois coal. The second boiler is located at Kanoria Chemicals and Industries in Renukoot, India, and is designed for 81 MW{sub th} output for captive power requirement, firing high ash, low sulfur coal. This boiler was supplied by Thermax B and W Ltd., a joint venture company of B and W and Thermax of India. The choice of CFB technology was based on its fuel flexibility, cost effectiveness and environmental benefits for solid fuels. Based on the broad experience in designing utility and industrial boilers for operation worldwide, B and W has developed a cost effective and compact atmospheric pressure IR-CFB boiler. The B and W IR-CFB boiler design is distinctive in its use of U-beam particle separators. Worldwide, B and W offers IF-CFB boilers up to 175 MW{sub th}, both reheat and non-reheat, and is pursuing units up to 350 MW{sub th}. This paper reviews the general description of each IR-CFB boiler, design and performance aspects, as well as overall operating experiences. The boiler availabilities including maintenance aspects and emissions data will be presented.
