Our client is a provider of emission technology solutions to the European Markets. His challenge was to reduce NO emissions from a coal fired 280 MW plant by at least 30% – with no increase (and preferably a decrease) in unburned carbon.

Utilizing advanced CFD modeling, and working closely with the client, SAS was able to determine the precise furnace modifications that were required to achieve the required reduction in NO – without increasing unburned carbon.

At start-up: a 35% decrease was achieved, along with a net decrease in unburned carbon – resulting in increased boiler efficiency.

Our client had a concept – can pollution (CO emissions) be reduced at a vent termination?

Working with our client, we identified a low temperature CO catalyst, found vendors, developed prototypes via CFD modeling and assisted through the certification (UL) phases – up to product “rollout.”

A flare vendor in Tulsa was required to demonstrate that flame height from a multi-point flare would not exceed the height of the enclosure.

Working with our client, measurements were taken from a single burner (actual flare had hundreds of burners) in and out of the wind. This information was used to calibrate a CFD model – and was then extended to the full design of hundreds of burners. Analysis indicated that the proposed design was 20% to short – so the enclosure was re-designed.

On start-up, no flame was observed above the enclosure – preventing potentially costly field modifications to the flare enclosure.
