VAPOPREX 3GN

• Standard design pressure 12 bars, 15 bars (higher pressure upon request).

• Steam production (at 12 bars) from 1.6 to 25 t/h.

• Amply sized evaporating chamber with large heat exchange area for the production of high quality saturated steam.

• Combustion chamber reinforced with omega or wedge joints.

• Burner fixed to the burner anchor plate.

• Tube bundle can be cleaned without removing the burner, by simply opening the two front and two rear doors.

• Possibility to access the furnace by removing the rear cover plate.

• Heat loss to the surrounding environment is limited by a suitable layer of high-density mineral wool insulation on the boiler body.

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

• 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.

• The water circuit can be inspected through ovalshaped manholes and head holes, while a circular manhole provides access to the furnace through the rear smokebox. Maintenance is further simplified by the walkable platform on the top part of the boiler.

• Ladder and walkway for safe access to the walkable platform on top of the boiler.

ACCESSORIES AVAILABLE ON REQUEST

• Economiser: a water-flue gas heat exchanger that increases efficiency by around 4%. Its configuration and position are defined based on customer requirements.

• Modulating supply system for optimum water level management in combination with an economiser.

• Air preheater: a flue gas/air heat exchanger to be installed in the flue gas circuit between the boiler and the chimney. This increases thermal efficiency by around 4%. This solution requires an industrial burner with separate fan to be installed upstream of the preheater.

• Steam superheater.

• Burner: brand and type chosen based on customer specifications.

• Second stand-by supply pump with valves.

• System for automatically draining sludge and dissolved salts that deposit on the bottom.

• Salinity (TDS) control system that measures dissolved salts in the water.

• Cooling tank for sampling boiler water.

• BMS 24H for up to 24 hours’ continuous unsupervised operation.

• BMS 72H for up to 72 hours’ continuous unsupervised operation.

• Second FAIL SAFE minimum level probe.

• FAIL SAFE maximum level probe.

• PLC control system fitted with high performance Touch Panel colour operator interface. The interface can be used to manage operation of the Boiler-Burner-Central Heating System.

• “VRC” condensate collection vessel.

• “VRD” atmospheric degasser.

• “DGST” thermophysical degasser.

• “BDV” drainage cooling tank.

• Water treatment system.

• Steam manifold.
