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.
