9.5 Heat exchanger
9.5.1 Heat exchanger description
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 following limits for the maximum flow are specified for a standard operating point of
τ
e
= 40 °C and
ϑ
G
= 70 °C. The
maximum flow v
max
in Nl/h of cooled air indicated, so after moisture has condensed. Values may differ for other dew points and
gas inlet temperatures. However, the physical facts are so vast we decided to omit the illustration. Please contact our experts for
clarification or refer to our calculation programme.
