WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
1. Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
4. Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
BS EN15502 - §8.13 prescribes the method for NOx emission assessment for all boilers up to 1000kW which is defined by a weighting formula. It differentiates between two boiler types: (older) fixed rate and (newer) modulating boilers. Modulating boilers adjust their fire/gas use according to the heat load, making them more efficient and
HURST EURO SERIES. 3-PASS FIRE TUBE DESIGN Stress Relieving “Wetback” Construction for Extra-Long Life 100 – 2000 BHP Steam 15-300 PSI. Boiler is of the three-pass, scotch type, built and stamped in accordance with the requirements of the ASME Code, and listed by the National Board of Boilers and Pressure Vessel Inspectors
Hurst is a custom manufacturer of engineered packaged boilers & boiler systems, biomass boiler systems, integrated PLC-based boiler controls & accessories. Low NOx modular boilers & burner configurations are available for all models, starting at 9. 5 hp, meeting all state environmental requirements, including SCAQMD.
Low NOx vs Ultra-Low NOx. The difference between Low NOx and Ultra-Low NOx is determined by local EPA standards and based on the type of heating equipment. For example, It's not uncommon to see an Ultra-Low NOx water heater that emits less than 10 nanograms of NO2 per joule of heat output (10 ng/J).
Hurst Pre Certified 4VT LOW NOx boilers can achieve less than 30 PPM NOx at 3% O2 without the need for induced flue gas recirculation. 4VT LN Series Shown with PowerFlame Burner Pre Certified SIMPLE INSTALLATION n Unit is skid mounted for easy handling. n Factory wired with wiring schematic included in the manual. n Efficient and space saving
LOW NOx Technologies Hurst Boiler and LOW NOx have become synonymous names within the boiler industry. Hurst Boiler & Welding Company developed its first low emission boiler in 1992, and has been incorporating new technologies to improve upon this ever since. Hurst Boilers are designed and engineered with larger furnaces.

As mentioned above, Miura is also introducing boilers that can achieve very low NOx emissions. Whether these “extra-ultra-low” NOx rules will be more widely encountered is not yet known. Another promising development is the C-RMB Burner developed by Todd Combustion, a division of John Zink Company.
LOW NOX BOILERS AND BURNERS Available for ALL Hurst Boilers. Our boilers can burn any liquid or gaseous fuel; and come in sizes from 100 to 2,500 horsepower with pressures to 450 PSI. Hurst boilers are designed and engineered with larger furnaces, providing for inherently lower NOx emissions.
