THREE PASS STEAM BOILER WITH WET BACK
Industrial Steam Boiler
This steam boiler has
three smoke passes and wet back, in order to increase the efficiency and reliability of the boier. It is designed to burn different types of liquid and gaseous fuels.
The first smoke pass is composed of a
coarrugated cylindrical furnace (it can be plane also), internal electro-welded to a house fire plate and
free of refractory concrete. In this furnace the fire from the burner pass to the second smoke pass.
The second smoke pass is made by a group of tubes just in front of the boiler, and finishes in another camera absolutely smoke-free of refractory cement, placed at the front of the boiler. This second smoke chamber is equipped with two hinged rear doors with hinges, absolutely practicable to do a proper maintenance, cleaning and inspection of the boiler.
The third smoke pass is made by another group of pips that come out of the front window of smoke and end up in the third box of smoke at the rear of the boiler. This third smoke chamber is also equipped with two hinged doors and practicable, allowing the proper maintenance of the boiler.
The steam boiler is made with all the necessary accessories and nozzles, mounted on a support basement that allow the thermal expansion of the equipmnen.
HIGHLIGHTS: DESIGN KEY POINTS
Design Standards: Computer Aided Design in compliance with latest CE pressure equipment directives and EN
Large Water and Steam Volume: Ready for peak steam draws - suitable for fluctuating steam demands
Large Heating Surface: Drier steam, higher heat absorption
Wet - Back Design: Maximum benefit from heating surface.
Low Counter - Pressure: Easier combustion, Less burner power consumption
Welded Construction: Robust construction, safe operation and easy tube replacement
Design with Minimum Refractor: Low thermal inertia, reduced service cost and better heat transfer
Optimum Combustion Chamber Sizes: Well - distributed thermal loading. More effective use of Radiation Heat Transfer Surfaces
Full combustion with low NOx
Three Pass / Three Draught: Suitable to operate with Rotary - cup Type or Pressure - jet Burners
High Efficiency: 91 % efficiency on LHV, without economizer... Savings on fuel
Wide Capacity Range: 1 ton/h - 25 ton/h steam
