TC-MIDI (+)
TC-MIDI+
The energy content of the sample gas and the required cooling capacity of the gas cooler is determined by three parameters: gas
temperature
ϑ
G
, dew point
τ
e
(moisture content) and volume flow v. The outlet dew point rises with increasing energy content of
the gas. The approved energy load from the gas is therefore determined by the tolerated rise in the dew point.
The following limits are specified for a standard operating point of
τ
e
= 50 °C and
ϑ
G
= 70 °C. The maximum volume flow v
max
in
Nl/h of cooled air is indicated, so after moisture has condensed.
If the values fall below
τ
e
and
ϑ
G
, the flow v
max
may be increased. For example, on the STG-2 heat exchanger the parameter triple
τ
e
= 40 °C,
ϑ
G
= 70 °C and v = 575 Nl/h may also be used in place of
τ
e
= 50 °C,
ϑ
G
= 70 °C and v = 320 Nl/h.
