Advanced Combustion Control - The Basis For Nox Reduction And Energy Saving In Glass Tank Furnaces

The formation of nitrogen oxide in glass tank furnaces is a result of high local temperatures and high local concentrations of nitrogen and oxygen in the furnace chamber, mostly as a consequence of ingressed air infiltration into the furnace chamber. Both over temperatures and air infiltration are not required to make good glass, but they are often the consequence of inappropriate input of gas, oil and combustion air into the furnace. Energy Saving DeNOx (EsDeNOx) Technology of Software & Technologie Glas GmbH (STG) is a typical early intervention method to reduce NOx formation and energy consumption and is explained in this paper.
