Low NOx PrimeFire Forehearth burners from Eclipse deliver significant reductions in fuel consumption and emissions in glass forehearth operations. The burners feature field proven combustion technology with the ability to reduce fuel consumption by over 60%, reduce NOx emissions by over 70%, and deliver a high glass yield. In addition, improved glass quality is also achieved due to the lower surface tension created with air-fuel combustion. Incorporating a nozzle-mix design, Forehearth burners eliminate the equipment costs associated with pre-mix style burners. The burner design also simplifies set-up and operation, and it can fire natural gas, propane, butane or mixed fuels.
