Clair has supplied Reverse Air Bag House (RABH) to a reputed cement manufacturer located in Nigeria. RABH was designed for a gas volume of 3,00,000 m3/h. The system was designed to provide the inlet and outlet of the RABH on the same side based on the ducting arrangement of the gases coming from the kiln. RABH was commissioned in 2017 and has since been running successfully meeting the design parameters. The detailed design parameters of the RABH are listed in Table 1.
