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
