Flue Gas Cleaning
In Waste to Energy and Waste Incineration processes, flue gas clean-up processes are essential in order to meet stringent environmental emissions targets.Running air pollution control (APC) plant efficiently requires management of sorbent and reagent use.
On-line monitoring of key process gases allows operators to respond in real time to changing conditions.
Bag-house filter plant inlet gas can be dosed with sorbents - lime, bicarbonate, activated carbon. HCl measurement helps control the use of expensive sorbents and minimise fly-ash production.
De-NOx control requires measurement of ammonia slip in order to control dosing of ammonia or urea.
TDLAS technology offers an ideal solution for measuring difficult to handle gases such as HCl and NH3.
