Abstract:
A method of controlling a system for feeding and burning a pulverized fuel of the type that comprises a glass melting furnace, a series of burners arranged in said glass melting furnace which are used alternately to carry out combustion and non-combustion cycles for the melting of the glass; at least a storage silo for storing and feeding the pulverized fuel; and at least a pulverized fuel feeding system which is filled up and emptied out with said pulverized material for providing a constant flow of said pulverized fuel to each of the burners during the class melting process, the method including the steps of:monitoring at least one operating variable involved in said lass melting furnace, which is based on at least a sensor, each sensor detecting a different variable during the glass melting process; monitoring and controlling the filled up and emptied out of said pulverized fuel feeding system based on the amount of pulverized fuel that is storaged in said pulverized fuel feeding system, providing a constant flow of said pulverized fuel to each of the burners; controlling the alternation of the combustion and non-combustion cycles in said burners of said glass melting furnace, based on the monitoring of the amount of pulverized fuel that is being fed to the burners and in said operating variables of the glass melting process; and calculating the alternation of the combustion and non-combustion cycles of said burners based on a real time.
