Low Fuel Consumption

• The perfect match between the boiler shell and burner ensures reliable and efficient operation. Efficiencies of 95% plus can be achieved when fitted with a Babcock Wanson matched economiser and heat recovery system.
• Consistent high thermal efficiency throughout the firing range is a key feature. Digital micro-modulation control with burner head geometry specifically designed to suit the BWD boiler means accurate control of excess air and lowest practicable operating costs.
• Electrical power consumption can be reduced by 30% to 50% by the use of variable speed control for the combustion air fan and feed water pump when specified.

Reduced Operating Cost

• Robust Construction for long life
• Direct access to the reversal chamber and ease of tube inspection simplifies mandatory inspection
• The outer walls of the flue gas reversal chamber are water cooled and provide high efficiency without the need for furnace tie rods which can be a weak point on traditional wet back boilers
• Standard equipment options include fully approved controls for attended, site supervised or fully unattended operation including the Babcock Wanson BW720 Operating System.
