A method and system feed and burn pulverized fuel, such as petroleum coke, in a glass melting furnace having burners associated with sealed regenerative chambers which act as heat exchangers. The system supplies the pulverized fuel for melting glass raw materials. The emissions of flue gases produced by the combustion process of the fuel in the furnace are controlled in order to maintain clean the flue gases and for reducing the emission of impurities from the fuel such as SOx, NOx, and particulates. The regenerative chambers are manufactured with selected refractories such as magnesium, zircon-silica-alumina, or magnesia and zirconium-silicate, for counteracting the erosive and corrosive effects produced by the combustion process of the fuel in the glass melting chamber. A burner feeds the petroleum coke and simultaneously mixes a primary air and pulverized fuel-air mixture for the burning of the pulverized fuel.

A method and system for feeding and burning pulverized fuel, such as petroleum coke, in a glass melting furnace, which includes a glass melting and a plurality of burners associated with a pair of sealed regenerative chambers disposed side-by-side which act as heat exchangers, the burners are arranged in a series of ports that are associated with the glass melting region of the furnace. The system includes means for supplying the pulverized fuel by each one of the burners for melting glass raw materials. The emissions of flue gases produced by the combustion process of the fuel in the furnace are controlled in order to maintain clean the flue gases and for reducing the emission of impurities from the fuel such as SOx, NOx and particulates. The regenerative chambers are manufactured with selected refractories such as, magnesium, zircon-silica-alumina or magnesia and zirconium-silicate, for conteracting the erosive and corrosive effects produced by the combustion process of the fuel in the glass melting chamber. A burner is also provided for feeding the petroleum coke, the burner including means to simultaneously mix a primary air and pulverized fuel-air mixture for the burning of the pulverized fuel.

An apparatus and method are provided for feeding a pulverized material which includes a first storage container for receiving and for discharging a flow of the pulverized material. The apparatus includes a separation chamber attached to the first storage container, which is alternately filled up or emptied out with the pulverized material. A second storage container is connected with an outlet of the separation chamber, for alternately filling the second storage container in accordance with a predetermined storage amount of pulverized material.
