PREXTHERM T3G N ASL

Superheated water generator with three flue passes

  • PREXTHERM T3G N ASL

Superheated water generator with pressurised combustion and high energy efficiency, three flue gas passes. Ready for operation in combination with a jet burner on liquid or gas fuel. The arrangement and  generous sizing of the combustion chamber with cooled end plate guarantee a low heating load and the possibility, when combined with a suitable burner, to ensure combustion with low NOx emissions.

Range consisting of 7 models, with useful heat outputs from 6,800 kW to 15,000 kW.

 


  • Technical Data

    • Standard design pressure: 6 or 8 bar.

    • These modern-concept and high-efficiency generators have been designed and developed in compliance with European Directive 2014/68/UE (PED) and the most recent national and European standards on pressurised recipients.

    Combustion chamber consisting of a large furnace reinforced with omega joints to guarantee operation at low heating loads, with completely water-cooled reversing chamber.

    Tube bundle on the second and third flue gas pass, with high heat exchange surface.

    • Suitable insulation of the boiler body using highdensity mineral wool protected by stainless steel plate limits heat loss to the surrounding environment. 79

    Large inspection doors both on the front, for flue gas reversal from the second to third pass, and at the rear for the smokebox.

    • The water circuit can be inspected through a manhole at the top of the boiler and a hand opening ring at the bottom.

    Rear manhole for inspecting the furnace.

    • The parts subject to pressure are all welded by qualified and IIS approved personnel, according to EN standards.

    Rear smokebox completely lined with high density mineral wool insulation.
