IMPROVED DESIGN FOR GLASS SMELTING KILNS.

Objetivo

THE OBJECTIVES ARE :

A) TO DEVELOP A COMPUTER CODE FOR THE SIMULATION AND DESIGN OF INDUSTRIAL GLASS KILN AND TO APPLY IT FOR ENGINEERING DESIGN OF GLASS MELTING KILNS.

B) TO CONDUCT A PROGRAMME OF EXPERIMENTS TO DETERMINE THE FLOW AND HEAT-TRANSFER CHARACTERISTICS IN THE GLASS MELTING KILN.

TO ACHIEVE THIS OBJECTIVE, COORDINATE EXPERIMENTAL PROGRAMME WILL BE CARRIED OUT IN THREE COUNTRIES (PORTUGAL, GERMANY, UNITED KINGDOM) AND THE RESULTS WILL BE USED TO GUIDE A FINAL EXPERIMENTAL PROGRAMME IN ONE OF THE FURNACES OF THE PORTUGUESE COMPANY, METAL. THE BASIS FOR THE NUMERICAL DESIGN PROCEDURE WILL BE PERFORMED IN LISBON AND FURTHER DEVELOPED IN THE THREE COUNTRIES.

THE DEVELOPMENT OF THE CALCULATION METHOD IS INNOVATED IN THAT NOVEL NUMERICAL PROCEDURES WILL BE REQUIRED TO DEAL WITH THE OXYGEN-RICH ATMOSPHERE AND WITH THE SUBSTANTIAL RADIATION. THESE DEVELOPMENTS WILL BE GUIDED BY EXPERIMENTS PERFORMED IN THE THREE CONFIGURATIONS, NAMELY A LOW TEMPERATURE SIMULATION OF A GLASS FURNACE, A COMBUSTING AXISYMMETRICAL FURNACE AND IN A FULL SCALE GLASS FURNACE. THIS OVERALL APPROACH IS TOTALLY NEW TO THE GLASS-FURNACE INDUSTRY.
A computer code for the simulation and design of industrial glass smelting kilns was developed. This computer code was used to improve the design and operating conditions of existing industrial glass kilns operating under oxyfuel conditions. A coordinated experimental programme was carried out under various configurations using a full scale glass kiln, an isothermal model of the kiln and using several model burners and fuel atomisers. The experiments were aimed at determining and optimising the flow and heat transfer characteristics of glass smelting kilns and at providing the basis for the development of the computer codes. The method of calculation uses novel numerical procedures to deal with the oxygen rich atmosphere and with the substantial radiative heat transfer occurring in the combustion chamber when it is operating under oxyfuel conditions.
THE R&D WORK IS DIVIDED IN TO THE FOLLOWING STEPS :

- COMPUTER CODE DEVELOPMENT
- COLD FLOW TESTS
- BURNER TESTING
- KILN TESTING
- COMPARISON OF CALCULATED AND MEASURED RESULTS
- PROVISIONS OF NEW DESIGNS AND DESIGN METHOD.
