For oil sands applications, saturated or superheated steam is generated with minimal required blowdown, increased efficiency, and improved ability to utilize liquid and gaseous fuels, including produced gas, heavy oil and residuals, as well as turbine exhaust gas and HRSG applications.
B&W’s industrial boilers can also accept feedwater quality lower than ABMA/ASME limits (sub-ASME) for drum boilers. To do this, B&W’s Multi-Circulation technology is used to control boiler circulation so that low solids water is supplied to the high heat flux zones in the boiler and high solids water is supplied to the low heat flux zones—thereby minimizing internal boiler tube deposition. The multi-circulation feature addresses concerns about the effects of sub-ASME quality feedwater on tube deposition by offering a unique design that maximizes thermal efficiency while minimizing the need to clean boiler tubes.
B&W’s industrial water-tube boilers are bottom supported, natural circulation designs with modularized construction that maximizes shop assembly and minimizes field erection, thereby providing more project scheduling certainty.
The units are fully drainable, can be designed for either forced or balanced draft operation, and are designed to meet specific steam temperature and pressure requirements within standardized configurations. Superheat can also be added when using the Multi-Circulation option to reduce water loss and improve overall plant efficiency in SAGD or power generation applications.
Units come in pre-engineered frame sizes to accommodate a range of steam conditions and capacity. They are designed to ship in shop-assembled modules within the shipping limitations of the oil sands region for size and weight.
