Economizers | CleanBoiler.org

Economizers designed for natural gas only, would likely plug-up if installed on a coal boiler and would face increased risk of corrosion if installed on an oil-fired boiler. Some units are designed to keep the flue gases above condensation temperature, and others are made of materials that resist the corrosive effect of condensed flue gases.
