Case Study

Burner Retrofit Options to Increase Efficiency and Reduce Emissions

If your boiler/burner (package) is like more than 200,000 commercial and industrial boiler packages in operation today, then it’s more than 20 years old. Which means it’s probably only 60 to 70 percent efficient and large amounts of fuel and associated cash are simply being wasted every minute the equipment is being operated.
