METHOD AND SYSTEM FOR CONTROLLING THE MAIN EXHAUST FAN Russian patent published in 2017 - IPC F27B21/14 

FIELD: ventilation.

SUBSTANCE: invention relates to a method of controlling the main exhaust fan and a system for implementing the method of control. Method involves obtaining an amount of the large gas duct arranged horizontally under the air curtain chamber and required for normal sintering, obtaining the required total negative pressure of the main exhaust fan by using, with the help of several data bases, the required negative pressure in the gas duct, negative pressure required for the flow rate in the pipeline, as well as negative pressure required for the flow rate at the air curtain window, and controlling the main exhaust fan according to the total required negative pressure of the main exhaust fan.

EFFECT: invention enables to avoid losses caused by excessive amount of air consumption, thus saving energy.
