UN METODO PARA LA CONDENSACION DE VAPORES DE AIRE EN PROCE- SOS TERMICOS DE REDUCCION.

摘要

Condensing zinc vapor by contacting hot gases containing zinc vapor with a spray of molten lead droplets within a multi-stage condenser with recirculation of the molten lead, wherein the temperature of the lead in an intermediate stage of the multi-stage condenser is controlled to be within the range of from 475 DEG to 515 DEG C, preferably by feeding hot lead from the first stage of the condenser into the intermediate stage via a duct leading through a baffle wall separating the first and intermediate stages.
