2.2.4
Ozone Generator System
**************************************************************************
NOTE: Delete this paragraph if an ozone generator
is not used. Horizontal tube, medium frequency
generators are the most common; however, since the
state of the art is constantly changing, verify that
other types of generators are not available or
appropriate for the particular application.
Coordinate pressure requirements with paragraph Air
Feed System. Typical pressure ranges required for
ozone systems are dependant upon the final ozone
outlet pressure, generally between 69 and 103 kPa
(10 and 15 psi) plus losses through the equipment.
**************************************************************************
Ozone generation equipment shall be continuous duty water cooled,
multi-tube glass or non-glass multitube dielectric [horizontal tube]
[vertical tube] assemblies contained in a pressure vessel [with hinged
gas-tight doors] with a rated design pressure of [_____] kPa psi. Each
unit shall be provided with [medium] [high] frequency electrical power
supply units including input and output transformers, power controller,
frequency inverter, harmonic mitigation equipment (if required). The
generator shall be provided with complete controls, [compatible with the
central control unit,] instrumentation, panels, appurtenances and
miscellaneous equipment required for a complete ozone generating system
using [oxygen] [air]. All equipment, valves, piping, associated
appurtenances shall be suitable for ozone in [oxygen] [air] service.
Generator design requirements are as follows:
Capacity
[_____] kg lbs per day
Gas flow rate to generator
[_____] cms scfm
Outlet pressure + 5 %)
[_____] kPa psi
Ozone concentration
[_____] percent
Generator vessel design pressure
[_____] kPa psi
Ozone output concentration turn down
[10:1] [_____]
Cooling water temperature rise at
[3] [_____] degrees C
rated production capacity (maximum)
[5] [_____] degrees F
Carrier gas rise across generator (max.)
[30] [_____] degrees C
[17] [_____] degrees F
Inlet hydrocarbon concentration (max)
[0] [_____] ppm
[480] [_____] volt, 3 phase,
60 hertz.
2.2.4.1
Ozone Generator Vessels
All ozone generator metal parts which come into contact with ozone or
cooling water shall be constructed of Type 316L stainless steel. The
