Title:
PULSE HEATING FURNACE SYSTEM AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/036709
Kind Code:
A1
Abstract:
The invention pertains to the field of metallurgical heating furnaces, and relates to a pulse heating furnace system and a control method. The pulse heating furnace system comprises a heating furnace, an air main pipe, and a gas main pipe. At least one furnace temperature control region is configured in the heating furnace. A single furnace temperature control region comprises a pulse burner and a furnace temperature measurement device. The air main pipe communicates with the pulse burner by means of an air branch pipe. The gas main pipe communicates with the pulse burner by means of a gas branch pipe. The control method comprises: adjusting an air capacity of each pulse burner on the basis of an air manifold pressure; adjusting a gas capacity of each pulse burner on the basis of a gas manifold pressure; and controlling a total gas volume and a total air volume. The invention provides system configurations of a pulse heating furnace and key process parameter configurations, and provides a control method for a pulse combustion system so as to effectively solve the problems in which an air-fuel ratio of an existing pulse heating furnace is difficult to control and a system pressure fluctuation is large, and leverage the advantages of the pulse heating furnace.
