…Study Shows Material Fuel and Electricity Savings
ClearSign Technologies Corporation, an emerging leader in industrial combustion and sensing technologies that support decarbonization, improve operational and energy efficiency, enable the use of hydrogen as a fuel and enhance safety while dramatically reducing emissions announces that the Ultra low NOx Burner Testing study has been completed by the California Gas Emerging Technologies (GET) Program and that the final report prepared by ICF has been released to the public.
The objective of the study sponsored by Southern California Gas Company (“SoCalGas”) was to test and quantify the emissions improvements and efficiency gains for the ClearSign Core™-Rogue ultra-low NOx boiler burner compared to a conventional (or baseline) ultra-low-NOx burner operating in the same boiler. Specifically, the report concluded that the ClearSign ultra-low NOx burner demonstrates both material fuel and electricity savings while producing ultra low NOx levels and was capable of NOx levels lower than the baseline burner.
The GET Program is a collaboration between California’s investor owned utilities to advance promising energy-efficient technologies. The program aims to identify and evaluate currently commercially available technologies and further market readiness of promising concepts.
The GET Program is funded by California utility customers, administered by SoCalGas and supported by the state’s other investor-owned utilities, SoCalGas®, San Diego Gas & Electric (SDG&E®), and Pacific Gas and Electric Company (PG&E®) under the auspices of the California Public Utilities Commission through a contract awarded to ICF, a global consulting and technology services provider.
“We were grateful for the sponsorship of the California GET Program and ICF who funded and managed this study to evaluate the relative operational efficiency and fuel consumption enabled by the latest low emission burner technology,” said Jim Deller, Ph.D., Chief Executive Officer of ClearSign.
“Reduced fuel consumption translates directly into operational cost savings and reduced carbon dioxide emissions for our customers. The third-party verified data documented in this report translates into approximately $80k per year savings in California energy costs for a mid-size 500hp boiler compared to a comparable industry standard burner technology, in addition to reducing over 500 tons of CO2 emissions per year. We believe this data presents a compelling proposition for our technologies,” concluded Dr. Deller.
Summary
The California GET Program report states that the ClearSign-Rogue burner demonstrated higher boiler operating efficiency, fuel savings, as well as electricity savings not only at the same Ultra Low NOx levels as the baseline mesh burner but also when operating at lower NOx levels below 2.5 ppm NOx. The ClearSign-Rogue burner was more energy efficient as it operated at the lowest excess air or O2 levels. The fuel savings ranged from 3.3% when the ClearSign-Rogue burner was operating at sub-2.5 ppm NOx to 4.7% at sub-9 ppm NOx at high fire. Savings in electricity ranged from 7% at sub-2.5 ppm NOx to 25% at sub-9 ppm NOx compared to the baseline mesh burner.

Having read this I thought it was very informative. I appreciate you taking the time and effort to put this article together. I once again find myself spending way to much time both reading and commenting. But so what, it was still worth it!
