Some Technical Proposals and Data for an Examination of the Thermal Performance of Glass Melting Tanks

JSGT 1936 V20 T596-T639

 The author stresses the need for greater uniformity both in definitions and in methods of calculating practical indices of performance, in order to facilitate a systematic improvement in tanks. With the aid of a numerical example it is shown how the results of practical investigations can be utilised in a simple manner, (a) to form a comparative opinion of the thermal conditions in a furnace, and (b) to calculate, approximately, in advance, thermal effects of constructional features, constructional alterations, and the possible limits of thermal improvement. Further proposals are made for t he calculation of average indices for standard values of specific melting load, of efficiency of regeneration, and of “useful heat” per kg of glass in cases where it appears desirable for purposes of comparison.
