D2.2 - High Temperature Sensors for In-Situ Process-Monitoring in Harsh Environments

F. Hammer, U. Kunstfeld & E. Messerschmid
Continuously increasing emission requirements and cost pressure inevitably lead to the optimization of combustion processes. Therefore, the exhaust gas losses have to be minimized by reducing the excess air to the so called emission rim. This is a point near stoichiometry where products of incomplete combustion (e.g. CO, H2) suddenly increase due to the lack of oxygen. Hence, a combustible gas sensing technology should be applied directly inside the exhaust pipe for realtime measurement. Harsh...
