Industrial 4 Pass Wetback Gas Oil Fired Steam Boiler

Industrial 4 Pass Wetback Gas Oil Fired Steam Boiler

Steam Capacity Range: 1-30 ton/hour, 60-2100BHP
Fuel Options: Natural Gas, LPG, LNG, Biogas, Diesel, Heavy Oil, Dual Fuel , Propane , #2 Fuel Oil
Steam Pressure: 0.7MPA-2.5MPA
Key Features:

Ultra-high efficiency up to 103%

Minimum maintenance almost 0 for boiler body

Integrated economizer&condenser, never leak

Safe&durable, long service life 30 years

High steam quality, dryness up to 99.9%

Advantage

  • Runway Type Reversal Chamber

    Reversal chamber adopted runway shape, compared with tradtional round shape,this structure greatly increase steam space, makes the steam dryness up to 99.83%, ensure the steam quality. (Increase the upper steam rising space, steam production space, and steam storage space).

  • Full corrugated and extended furnace, super large furnace design, low center layout structure.

    (1) Increase the high temperature area radiation heating surface

    (2) Increase the combustion space, full combustion, more energy-saving

    (3) Large furnace, diffuse flame, lower nitrogen;

  • Economizer&condenser Integration

    Material:ND Steel+Silicon-magnesium-aluminum alloy fin tub

    Feature:Better heat transfer performance and high heat exchange intensity ,Stronger acid corrosion resistance

    The sensible heat in the flue gas and the latent heat of condensation of water vapor are recovered to the maximum extent, the exhaust temperature is reduced; So the thermal efficiency of the boiler is improved, and NOX emissions are reduced.

  • Intelligent power-save automatic control

    (water replenishment as required /stable pressure)

    Adopt Swiss brand ADD inverter, perfect combination with combustion fan , feed water pump, and optimized PLC automatic control, boiler load meets the full-proportional personalized output. Wide frequency conversion makes the motor output more power-saving, energy-saving and stepless adjustment.
