Abstract
Hot briquetting apparatus for ferrous or non-ferrous particles has a furnace having upper and lower chambers. The particles are supplied to the lower chamber and leave the lower chamber through a discharge tube to enter a briquetting press. A passage is performed between the lower and upper chambers and sensing means sense the constituents of the gases in that passage. Control means control the air-to-fuel ratio of a zone of the lower chamber. The control means are connected to the output of the sensing means so as to maintain the atmosphere within the zone as a reducing atmosphere, the whole of the lower chamber being a reducing atmosphere.
Claims6
Hot briquetting apparatus for metallic particles comprising a furnace for heating metallic particles to the plastics range, means for supplying metallic particles to the furnace, sensing means for sensing the constituents of the combustion gases of the furnace, control means for controlling the air-to-fuel ratio of the furnace, and a briquetting press which receives heated metal particles from the furnace, said control means being connected to the output of the sensing means so as to maintain the atmosphere within the furnace as a reducing atmosphere.
