CDA
1.3 Application
The LAND CDA Incinerator Thermometer is designed for taking
measurements of the atmospheric temperature within waste incinerators.
It can be used for gas or flame temperature measurement in a variety of
plant applications, provided that there is sufficient CO
2
concentration at
a high temperature and an effective measurement sight path depth. The
measurement is unaffected by a cold CO
2
atmosphere, therefore it “sees
through” cold combustion atmospheres, measuring any hot atmosphere
beyond.
In a typical incinerator application, the
CDA is mounted externally onto the
incinerator wall, positioned approximately 2 metres above the bed. It is fixed
to a protective flanged sight tube which penetrates through the incinerator
wall. The thermometer sight path acts as an “invisible thermocouple”,
extending into the incinerator atmosphere (penetration depth depends upon
atmosphere conditions), where atmospheric temperature measurements
are taken.
The
CDA thermometer is fully protected from the harsh environments
encountered in incinerator applications by utilising the Land protective jacket
assembly which is air or water-cooled and an air-purged sighting tube.
