Near Zero NOx (NZN) / Ultra Low NOx (ULN) Firetube Boiler Burner
Complying with increasingly tough emissions requirements is a continued challenge for the boiler industry. Conventional ultra-low NOx burners have been pushed to their limits; they have become increasingly complex and costly, and in some regions, still fail to meet current NOx requirements. SCRs can meet these new emissions regulations, but they come with significant capital and operating cost as well as the need for additional training to handle required catalysts and reagents.

The GET Program Project
The goal of this GET project was to test and quantify the emissions improvements and efficiency gains for the ClearSign’s Core™-Rogue ultra-low-NOx boiler burner compared to conventional (baseline) ultra-low-NOx burners. An industry standard mesh-style burner was selected as a baseline for this study.
The study found that the ClearSign Core-Rogue burner demonstrated higher boiler operating efficiencies, especially at the 66% and 84% firing rates. At the 66% firing rate, the ClearSign-Rogue S9 was more efficient than the baseline mesh burner by 3.5% on average and the NZN was more efficient than the baseline mesh burner by around 2.4%. At the 84% firing rate, these gains for the ClearSign-Rogue burner were 3.2% and 2.8%, respectively. Compared to the baseline mesh burner, the ClearSign-Rogue burner offers fuel savings at both NOx levels with the savings being greater at sub-9 ppm operation, given the lower operating O2 and higher efficiency gains. At the 66% firing rate, the ClearSign-Rogue S9 had fuel savings of 5.4%, and the NZN had fuel savings of 3.8% compared to the baseline mesh burner. At the 84% firing rate, the ClearSign-Rogue S9 burner had fuel savings of 4.7%, and the ClearSign-Rogue burner at NZN conditions had fuel savings of 3.3% compared to the baseline burner. There were electrical savings that ranged from 7% to 25% at NZN mode and S9 mode, respectively.
