METHOD OF AND APPARATUS FOR CHARGING MATERIALS INTO A FURNACE

摘要

A method for introducing pulverulent matter into a cupola or a blast furnace is proposed. The introduction takes place in the flue gases or in the oxidising gas feed tuyeres. It is the granules themselves that form the sealing between the pressurised zone and the outside. An alternative form has no moving component in contact with the granules, another one employs an endless screw rotating in a pipe. The method is suited in particular to the reintroduction into the feed tuyeres of dust collected in the flue gases and to the introduction of pulverulent matter into the flue gases.
