RECUPERATORS OF MELTING BUBBLING FURNACES

Information on the use of tubular radiation recuperators on melting bubble furnaces is presented. The reasons that subsequently affect deterioration of the recuperators performance have been analyzed. New structure of the recuperators, in which a hanging top collector with a counterweight and appropriate loop-type expansion joints are applied to prevent uncontrolled deformation of heat-receiving pipes, have been designed based on the analysis of the operation of recuperators of melting bubbling furnaces. New design allows to increase efficiency of the recuperator application, cleaning and repair of the pipes are possible without dismantling of the stack brick work. Bibl. 6, Fig. 5, Tab. 2.
