Fuel Saving Burner Practices for a Regenerative Glass Furnace

Potential for energy conservation in the glass industry

“…The cold inspirated air is then replaced with 2000+°F air from the regenerators. This preheated combustion air contributes 40 Btu per standard cubic foot to the melting process (Neff 1985).…”

“…There is an approximate ratio of 2.5 mole% of cold air introduced into the furnace to 1% of additional fuel use (Neff 1985). It is difficult to predict the energy savings associated with sealing in a gas burner unless the volume of inspirated air is known.…”

“…Furnaces vary widely in the amount of inspirated air due to differences in burner block openings, burner firing positions, furnace pressure, and fuel-firing rates. Experience indicates that the amount of inspirated air ranges from about 5% to 15% of the stoichiometric combustion air (Neff 1985).…”
