    4. Function and Assembly The HygroMatik Steam Injection Humidifier comprises 4 basic elements: • Separator • Control valve with or without control operation • Steam Lances • Additional materials There is a stainless steel version Type A and a mixed material version Type C 4.1 Function...

  • Page 10: Strainer

    5. Strainer There should be a strainer installed in the steam supply line directly in front of every separator. Only if this is done can it be guaranteed that there are no foreign particles in the humidifier unit. Valve cone and valve face in both the control valve and steam trap are sensitive to fouling.

  • Page 11: Separator

    6. Separator The stainless steel separator is the essential component for moisture separation. The separator is available in versions 20 and 40. The separator size is dependent upon the desired steam output and available steam pressure. 6.1 Function Steam flows through the pipe union (1) into the separator. Steam and condensate are separated by the joint action of the inlet pipe (2) and the spiral-shaped flow system.

    In order to comply with DIN 32 730* an electrical actuator must have a fail-safe function so that in the case of a power failure the Type Hygromatik B-4115001 control valve is reset into a safe position (fully closed). Pneumatic Actuator Pneumatic Actuators are controlled using compressed air (e.g.

  • Page 14: Start-Up Safety Switch

    8. Start-up safety switch The start-up safety switch ensures that no condensate from the steam network has entered the air conditioning duct over the steaml lances. Electrical Start-up safety switch With an electrical actuator the supply voltage is looped through the start-up safety switch.

  • Page 15: Steam Lances

    9. Steam Lances In the steam lances (1) dry steam is blown out of specially formed nozzles (2). They are designed for low noise steam emission. The nozzles take steam from the driest area in the steam lance centre. In order to prevent accumulated condensate or aerosol droplets from being transported with the steam, the steam lances are provided with a steam lance heating system (3).

  • Page 23: Humidification Output

    13. Humidification Output The maximum humidification output [kg/h] of one steam injection unit depends upon the available steam pressure in bar. Maximum humidification output can be over 700 kg/h and oper- ating pressure of pmax = 4 bar. 13.1 Output Graphs The following graphs serve as an aid to determining the neces- sary Kvs-Values for the control valve, a given steam pressure and a desired humidification output.
  • Page 24 Example: Desired humidification output: 110 kg/h Operating pressure, p = 2 bar The length and number of steam lances is determined by the duct dimensions. See Section 9 "Steam Lances". Result: Follow the operating pressure line until the desired humidifica- tion output in kg/h is reached.
