CDA

Waste Incinerators

The CDA thermometer is intended for measurement of the atmosphere temperature in waste incinerators.It can be used for gas or flame temperature measurement in a variety of other plant situations provided there is sufficient path length.
Its reading is unaffected by cold CO2so it will ‘see through’ a cold combustion atmosphere to measure a hot atmosphere beyond.

Key Benefits

  • The CDA thermometer fits the standard Land System 4 mounting accessories and protection jackets which can be air or water-cooled. The sighting tube should normally be air-purged.
  • The thermometer operates on a simple 2-wire loop connection and outputs a 4 to 20mA signal linear with temperature.
  • The thermometer reading is insensitive to the presence of gasses other than CO2 and is relatively insensitive to particulate matter in the atmosphere – i.e. it measures true gas temperature.

It can be used for gas or flame temperature measurement in a variety of other plant situations provided there is sufficient path length. Its reading is unaffected by cold CO2 so it will ‘see through’ a cold combustion atmosphere to measure a hot atmosphere beyond.

In an incinerator it can be pictured as an ‘invisible thermocouple’ extending into the atmosphere above the bed by perhaps 2 metres/6.5 feet (penetration depth depends on atmosphere conditions). In use it is fitted wholly external to the incinerator, usually to a flanged tube penetrating the wall.
