SVT - Rapid Steam Generator with Boiler Operator Exemption

Relevant Exemptions Under D.Lgs n. 93/2000 - Art. 2, Exclusions (Point F)

SVT - Rapid Steam Generator with Boiler Operator Exemption

The SVT steam generators are designed to comply with the Italian Legislative Decree 93/2000, which exempts certain steam boilers from the need for continuous monitoring by a qualified boiler operator (licensed fireman). These units do not require specific start-up procedures, making them ideal for applications where efficiency and simplicity are essential.

 

Relevant Exemptions Under D.Lgs n. 93/2000 - Art. 2, Exclusions (Point F):

This decree does not apply to the following devices, except for those indicated in Article 1, letter c):

  • Pressure devices used for quick coffee preparation
  • Domestic pressure cookers
  • Generators, containers, and piping with a maximum allowable pressure not exceeding 0.5 bar
  • Fixed fire extinguishers with a maximum allowable pressure not exceeding 10 bar or internal diameter smaller than 400 mm; portable extinguishers with gas cartridges at or below 18 bar
  • Steam generators for water or superheated water with a total volume up to 25 liters and a maximum pressure of 32 bar
  • Steam generators for water or superheated water where the product of the maximum allowable pressure in bar multiplied by the capacity in liters does not exceed 300, and the maximum allowable pressure is 10 bar.

Key Components:

  • Pressure Vessel:
    Constructed with certified carbon steel plate, vertical cylindrical structure, welded to tube plates, and equipped with fittings for valves and instrumentation.

  • Combustion Chamber:
    Built from certified carbon steel, the cylindrical vertical chamber is designed for optimal fuel-air mixing, ensuring efficient combustion.

  • Tube Bundle:
    Smooth vertical tubes made from certified thick carbon steel for heat transfer.

  • Tube Plates:
    Upper and lower tube plates made from thick carbon steel, perforated and drilled for the smoke tubes.

  • Support and Insulation:
    Includes a removable bolted top for internal inspection, steel base with flanges for the pressure vessel assembly, and high thermal insulation covered with aluminum sheeting.

Regulation and Control Equipment:

  • Pressure Monitoring:

    • Pressure sensor
    • Electronic pressure regulator
    • ON/OFF level control system with probes to manage the pump.
  • Control Instruments:

    • Compliant pressure gauge with shut-off valve and test flange
    • Reflection-type level indicators
    • Integrated electronic pressure indicator

 

Safety Features:

  • Certified high-pressure safety pressure switch
  • Approved safety valve
  • Dual low-level safety regulators with manual reset

 

Valves:

  • Steam outlet valve
  • Water inlet isolation and check valves
  • Pneumatic and manual venting valves
  • Alkalinity discharge valve

 

Feedwater System:

  • ON/OFF operation with centrifugal pump conforming to current regulations, mounted on a base with seals up to 120°C
  • High-pressure flexible hoses.

 

Electrical Panel:

  • Steel painted box with IP54 protection rating
  • Main switch with mechanical safety lock

Optional Inox Construction (AISI 304 or AISI 316):

Available upon request to comply with HTM 2031 standards for clean steam generation. This type of steam, essential in sectors like healthcare and food processing, must meet the British Pharmacopoeia Water for Injection standards. Clean steam ensures there are no contaminants, making it suitable for sterilizing medical devices and hospital equipment.


These generators are ideal for industries requiring high-quality, low-maintenance steam production, without the need for constant supervision. The SVT series offers a solution for applications in various sectors, ensuring operational efficiency, cost-effectiveness, and compliance with industry standards.
