<P>PROBLEM TO BE SOLVED: To provide a method for control of exhaust heat recovery equipment, capable of preventing the amount of generated steam from exceeding rated volume, by controlling the amount of steam generated in a boiler installed in the exhaust heat recovery equipment without changing the cooling capacity of a sintered ore cooling machine. <P>SOLUTION: The sintered ore cooling machine 1 includes: a cooler pan 10 which moves sintered ore supplied onto an upper surface from an ore supply part toward an ore discharge part; an air blowing duct 11 which is located below the cooler pan 10 and supplies cooling gas; and an exhaust duct 12 which is located above the cooler pan 10 and recovers exhaust gas. The method is provided for controlling the exhaust heat recovery equipment 2, which exchanges heat of exhaust gas recovered by the exhaust hood 12 with water supplied from a water supply system and supplies the heat-exchanged exhaust gas as cooling gas to an air blowing duct 11 in the sintered ore cooling machine, and in which a boiler 20 for generating steam is installed. The method is characterized by controlling the amount of generated steam to below the rated capacity of the exhaust heat recovery equipment 2 by adjusting the pressure of the steam generated by the boiler 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
