FIRE TUBE BOILERS NBWB Series 250 kg/h to 2,500 kg/h - 175 to 1,750 kW ENERGY SAVING, REDUCED OPERATING COSTS, ENVIRONMENTAL PROTECTION Standard features The NBWB is a compact, economical and exceptionally robust boiler, with an innovative design integrating the latest updates from Babcock Wanson. The NBWB range is fully packaged, factory assembled and tested ready for rapid installation and commissioning on site. ■■High Efficiency design The NBWB Series covers the smaller end of the Babcock Wanson fire tube boiler range. Built to the highest standards these boilers have outputs between 175 kW and 1,750 kW – 250 kg/h to 2500 kg/h (steam at 10 barg from feed water at 60°C). The NBWB range raises steam with a net combustion efficiency of up to 95.6% when fitted with the optional economiser. ■■Design The NBWB range combines a simple yet robust design with innovative technology for outstanding reliability and performance. Optimum efficiency The efficiency of the NBWB range of boilers is fully optimised due to our in-house research and development. Helical rings are located inside the boiler tubes which force the combustion gasses to pass through the tubes with a spiral motion thereby substantially improving heat exchange. A NBWB 100 boiler with an output of 1 t/h is capable of reaching 90.7% combustion efficiency in standard form (based on fuel NCV) and up to 95.6% when fitted with the optional economiser. Babcock Wanson fire-tube helical rings Babcock Wanson only fit burners that are designed for the best possible boiler/burner match thereby providing a wide operating range. ■■Fuels Natural gas, LPG, light fuel oil and dual fuel (gas/light fuel oil). ■■Easy maintenance Simple and complete access is a key feature of the NBWB range of boilers from Babcock Wanson. The complete rear tube plate is easily accessible by sliding the rear door along a handling rail provided as standard. This greatly simplifies boiler servicing and statutory periodic inspections. ■ Optional features ❚ Flue gas economiser (from 1,000 kg/h). ❚ Boiler feedwater tank and water treatment. ❚ Remote monitoring systems. ❚ Turnkey boiler house and skid mounted assemblies. ❚ Ancillary boiler house equipment. Quality NBWB boilers and controls are constructed in accordance with the latest European and international standards EN12953, EN 676, EN 267, NFE,TRD and BG01. The CE marking covers both the boiler and the burner, under the responsibility of one single manufacturer in accordance with 97/23-0038. Higher Steam Loads For higher steam outputs please see our range of BWD and BWR advanced high efficiency fire tube boilers which provide steam outputs of up to 27,000 kg/h.
