NBWB Series
Steam outputs from 250 kg/h to 2500 kg/h
The NBWB series of fire tube steam boilers provides users with high quality dry steam up to 2500 kg/h, whilst maintaining low fuel consumption and operating costs.
Low Fuel Consumption
- Fully optimised and highly efficient in standard construction due to the use of fire tube helical rings which direct the flue gas into a swirling motion.
- Efficiencies of 95% and higher can be achieved when fitted with a matched Babcock Wanson economiser and heat recovery system.
- 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
- Ease of access for simplified inspection and maintenance.
- Options include fully approved controls for attended, site supervised or fully unattended operation for economic operation and ease of use.
