Bryan Separable Tank Tray-Type Deaerators from Bryan Steam LLC are available in 10 models with standard capacities ranging from 70,000 to 300,000 lb/hr (2,030 to 8,695 Bhp). They are ideal for high volume installations. The deaerators pre-heat and deaerate boiler feedwater, improving system efficiency and reducing operating costs, even where wide load swings occur. Bryan separable tank tray-type deaerators minimize the risk of thermal shock, reduce the chances of pressure drop and remove oxygen (to .005 cc/l) and carbon dioxide (to zero measurable). These non-condensable gases can inhibit heat transfer and corrode the boiler. The tray-type deaerators also recycle steam, saving energy and reducing the amount of chemicals used for conditioning water. Bryan Steam LLC.
