Reduced particle carry-over means less fly ash, which is costly to dispose of. To the right we see improved, more central flames, reducing the dead zones and utilising the furnace volume better. If space is tight two Ecotubes from each side can be used. (3/3)

This is a view down to the fuel bed in a 150 MW biomass boiler without (left) and with (right) Ecotubes in operation. The benefit of Ecotubes on flames and carry-over of unburned fuel is clear in the pictures. (2/3)

The Ecotubes were installed at two different levels to allow operation at loads between 15% and 100% and still injecting the SNCR reagents at a suitable temperature for an effective SNCR reaction to take place at all loads. (2/2)

This is one of the Ecotube installed on a 75 MWth boiler burning biomass and demolition wood. Two Ecotubes with combined OFA and integrated SNCR were installed in 2024 and achieved a NOx-reduction from baseline 380-400 mg/Nm3 @ 6% O2 to 75-95 mg/Nm3 @ 6% O2 with Ecotubes in operation. (1/2)

The Ecotubes can also be equipped with SNCR injection to achieve further NOx-reduction (70-75%). Flue gas recirculation and humidification can also be included. Every boiler is unique and so are our systems to cater for that. (4/4)

The third step in the project (the first hardware step) is the installation of an Ecotube system. Ecotubes can operate with air only providing effective mixing and combustion staging to deliver significant NOx-reduction without reagents like Urea or ammonia. (3/4)
