The Application of the Results of Some Steel Furnace Trials to Glass Furnace Practice
JSGT 1948 V32 T189-T208
Furnace research can be judged by its effects upon the quality of the product, refractory life, output and thermal efficiency of the furnace. While the emphasis in glass tank furnace research is somewhat different from that in steel furnaces a study of port design in the latter gave results which can be of interest in the former. Three furnaces of standard Venturi and Maerz design were compared by trials in which all the variables relevant to combustion were measured, a Heat Flow Meter giving the direct measure of the flame radiation. It was concluded that : (i) both in steel and glass furnaces the use of instruments to a considerably greater extent is probably the most important single line of improvement, particularly by the use of CO2 or O2 meters to control the excess air and air infiltration; (ii) flames are in general too long and ports giving better mixing are therefore desirable.
