Abstract:
A system (10) is disclosed for cyclically charging limestone in a regenerating oven (20) comprising storing and supplying means adapted to receive limestone supplied from charging means, to store and supply it alternately and cyclically to a first and a second vat (21; 23) of the oven (20) by interposing airtightly sealed supply valves, an internal pressure equalizing device of the storing means with a pressure of an environment in which the charging means operate or an internal pressure of the oven (20); a process is further disclosed for charging limestone in a regenerating oven (20) through such system (10).
Abstract:
A fuel delivering terminal (1) is disclosed adapted to be connected to a delivery end of a combustion lance (3) of lime regenerating ovens, wherein D is the external diameter of the terminal (1) and is greater that the internal diameter d of the delivery end of the combustion lance (3) ; a combustion lance equipped with the terminal (1) and a system and a process for controlling the fuel supply flow through such lances are also disclosed.
