Title: Furnace for treating briquetted zinc residues - with high yield of volatile and non volatile metals, and high thermal efficiency
IPC: C22B19/00
Filed: 1976-08-10
Abstract: Furnace is for sepg. useful metals from a material contg. zinc. The novelty is the use of an inclined or V-shaped hearth with tuyeres distributed along the hearth and a bottom tap hole for removing matter and/or slag, plus registers or dampers. The front ends form a 'V' or a slope, each damper matching the position of the tuyeres. The furnace pref. has an upper inlet for sec. air and a recuperator consisting of a boiler producing high pressure, steam, plus a bag filter collecting ZnO. The raw material is pref. briquetted using lignosulphite lye and powdered coal. The tuyere blast preheated to >=450 degrees C.; and the reaction zone temp. >=1300 degrees C. Residues from the pyrometallurgical treatment of zinc may be treated to separate volatile from nonvolatile metals with a high yield and high thermal efficiency, using the steam in a turbine generating electricity.

Title: Steam generator tube grille construction - with frame joined to grille strips for transport and erection only
IPC: F28F9/013
Filed: 1976-12-07
Abstract: The system is for the construction of a grille supporting and positioning steam generator tubes, particularly in natural-circulation pressurised water reactors. The grille proper is formed by strips of material having a particular coefficient of thermal expansion, and the frame of another material with a lesser or equal thermal expansion coefficient. The other frame is joined to the strips during assembly, so as to be fixed to them for the whole time necessary for construction, transport and erection. When the generator is set to work the frame is no longer fixed to the strips. Thus is encloses and supports them but allows them to expand at a different rate.
