Injecting carbonaceous dust e.g. petroleum coke dust into cupola furnace, comprises supplying petroleum coke dust into distributor by furnace lances, where dust supply is positioned between a dosing tank and the distributor

摘要

The method comprises supplying a petroleum coke dust into a distributor using furnace lances (20). A dust supply is positioned between a dosing tank and the distributor, and is configured for independently switching and/or controlling conveyor stations. The dust entered to the distributor is measured by online measurement and/or a pressure sensor. The online measurement values are calibrated by the pressure measurement values, or vice versa. The switching of the conveyor stations is carried out to reduce a predetermined value of flow of dust.

A dust supply is positioned between a dosing tank and the distributor, and is configured for independently switching and/or controlling conveyor stations. The dust entered to the distributor is measured by online measurement and/or a pressure sensor. The online measurement values are calibrated by the pressure measurement values, or vice versa. The switching of the conveyor stations is carried out to reduce a predetermined value of flow of dust. An amount of dust and/or flow rate of the dust is measured before a dust manifold pressure. The conveyor stations are operated in an alternative manner. An independent claim is included for a system for injecting carbonaceous dust into a cupola furnace.
