BWR Fire Tube Boilers feature three pass design and include a tubular construction flue gas reversal chamber. This proven feature, unique to Babcock Wanson, enhances water circulation thereby greatly reducing the risk of internal fouling (sludge accumulation in the bottom of the boiler). Furnace tie rods are not required and uniform shell expansion gives the flexibility to meet large steam load changes with minimal operational stress. High quality dry steam is provided due to generous steam space and integral separator.
Low Fuel Consumption
The perfect match between the boiler shell and burner ensures reliable and efficient operation. Efficiencies in excess of 98% (R-Eco) and 105% (Condensing) can be achieved when fitted with a Babcock Wanson matched economiser and heat recovery system.
Consistent high thermal efficiency throughout the firing range. Digital micro- modulation control with burner head geometry specifically designed to suit the BWR boiler provides very high turndown ratios with accurate control of excess air and lowest practicable operating costs.
Electrical power consumption is reduced by 30% to 50% by the use of variable speed control.
Reduced Operating Cost
Robust Construction for long life
No risk of internal fouling
The flue gas reversal chamber is fully water cooled ensuring high efficiency and minimum maintenance requirements. Ease of access to the chamber simplifies inspection.
