The Babcock and Wilcox (B and W) internal recirculation CFB (IR-CFB) boiler is unique in design. Worldwide, B and W offers IR-CFB boilers up to 150 MW(e) both reheat and non-reheat, and is pursuing units up to 300 MW(e). This paper discusses an overview and status of the construction, commissioning, initial start-up operation and milestones of the ongoing 25 MW(e) IR-CFB boiler project at Kanoria Chemicals and Industries Ltd., Renukoot, India. This IR-CFB boiler is designed, supplied and installed by Thermax Babcock and Wilcox Ltd. (TBW), a joint venture company of the B and W and Thermax in India. The boiler parameters are, steam flow of 29.2 kg/s (23,420 lbs/hr), 6.4 MPa (925 psig), and 485 C (905 F) with feedwater temperature of 180 C (356 F). The boiler will utilize high-ash content (> 45%), subbituminous coal with a heating value of 3,500 KCal/kg (6,300 Btu/lb). This paper also discusses the various aspects of the boiler design, performance, auxiliary equipment, advantages and initial start-up operating performance.
