Abstract
The Nordic Pot Furnace Project is financed by the Nordic gas and glass industry. The purpose of the project was to develop a competitive gas-fired alternative to oil and electrically heated pot furnaces for the manufacture of glass. The objective was to increase prime-quality glass production by 2-4%, lower energy consumption by 10% and halve NO{sub x} emissions. The project was divided into five substages, these being: I Prestudies, II Water model trials, III Pilot furnace with crucible simulator, IV Field experiment in production, and V Full-scale trial. Substages I to IV, inclusive, have been completed and are summarized in this report. Water model trials established that: Tangentially directed concurrent burners at the top and bottom of the pot provide good conditions for excellent pot heating. If the upper burner is swapped for a flat-flame burner positioned in the vault above the pot, the flow distribution achieved in the furnace further serves to facilitate the control of heat distribution in the furnace. The concept was tried out on several different burners during the pilot trials in Malmoe, Sweden. Low NO{sub x} values were obtained for the low-NO{sub x} burner combination, in which emissions were reduced to half by comparison with

The position of the operating thermocouple in the furnace chamber and its siting in the furnace wall proved to be of great importance to furnace control. Measurement results from the trial and the glassworkers` views confirm that gas is perfectly able to compete with oil and electricity from all the angles investigated. (EG)}
