Abstract

630,072. Furnaces. DOWSON & MASON GAS PLANT CO., Ltd., and LEONARD, L. G. A. Jan. 30, 1946, No. 2972. [Classes 51 (i) and 51 (ii)] A heat treatment furnace having burners so arranged as to produce a continuous circulation of gases within the heating chamber in planes transverse to its length is provided in the walls with ducts M leading spent gases to ports E with venturi throats O in advance of liquid fuel burners F which are disposed in intercalated fashion at the ends of transverse troughs L. Spaced refractory tiles Q form baffles above and slightly longer than the flames, some of the recirculated gases being induced to pass through the spaces S so formed. Specifications 616,166 and 616,167 are referred to.
