Low NOx Boilers

From 10HP to 2500HP and up to 450 PSI Design

Low Emission Boiler and Burner Technology Engineered for the Environment

Boiler and Burner Technology Engineering for a Cleaner Environment. Hurst developed its first low emission (Low NOx) boiler in 1992, and has been incorporating new technologies to improve upon green boilers ever since.

Our boilers can burn any liquid or gaseous fuel; and come in sizes from 100 to 2,500 horsepower with pressures to 450 PSI. Hurst boilers are designed and engineered with larger furnaces, providing for inherently lower NOx emissions. To produce lower emissions, our boilers employ
technologies such as; gas and air pre-mix, flue gas recirculation, and thermal reduction. We have also developed new control systems that utilize microprocessor-based fuel/air ratios offering superior combustion.
