TERNOX D 2P - - Hot Water Boilers

Hot water boiler, with 3 effective smoke passes, wet bottom, horizontal design.

The TERNOX D 2P series is a family of hot water boilers designed for a maximum safety pressure of up to 6 bar or higher on request. The range includes various models with an output from 2000 to 22000 kW.

General features:
The generator with 3 effective smoke passes is made up of a cylindrical furnace with a wet bottom in which the flame develops and runs through the furnace (1st smoke pass) and, at the bottom, through the inversion chamber, enters the tube bundle of the 2nd smoke pass. The fumes return to the front where they enter the tube bundle of the 3rd smoke pass.
Exiting the tube bundle, the fumes are collected in the rear smoke chamber and conveyed to the chimney.

  • Boiler body: the components of the boiler body, outer shell, furnace, inversion chamber, tube plates and tube bundle are made of quality steel in accordance with current regulations.
    The materials used are accompanied by manufacturing certificates certifying the chemical and mechanical characteristics and the controls during the production cycle and therefore their suitability for use. The inversion chamber is made with flat tube plates. The welded joints are carried out according to procedures approved by suitably qualified personnel.
    Once manufacturing is complete, each pressure carrying part is subjected to testing by carrying out the hydraulic test.
  • Smoke pipes: making up the quality steel tube bundle, are welded to the tube plates by means of qualified automatic procedures. Finally, the pipes are headed by counterbore eliminating the protrusions from the plate.
  • Front doors: made of steel sheet, hermetically sealed against fumes leakage, they are internally lined with refractory insulating concrete. The burner is fixed on a dedicated independent flange, with lifting eyebolts.
  • Rear smoke chamber: made of steel sheet, is insulated by casting of suitable material, it is complete with horizontal flanged connection for flue gas evacuation and with inspection and cleaning doors.
  • Base: it consists of a frame in steel profiles electro-welded to the tube plates.
  • Insulation of the outer shell: thermal insulation is ensured by a mineral wool mattress, 100 mm thick, externally protected by an aluminum foil (stainless steel on request).
