Our extensive worldwide experience in designing, manufacturing, installing and servicing more than 700 RB boilers gives our customers the reliability and dependability they demand. B&W's RB boiler incorporates natural circulation which takes advantage of the density difference between water in the downcomers and the steam/water mixture in the furnace tubes. With natural circulation, no pumps are required, so auxiliary power requirements are reduced and availability is improved. B&W's RB boiler is typically designed with a parallel back-end that allows gas biasing reheat steam temperature control.
Our surface arrangement design provides benefits for added reliability and availability, including:
Our vast design and operating experience gives us the unique capability to accommodate many worldwide coals and blends while meeting required steam conditions without sacrificing reliability or availability.
