<P>PROBLEM TO BE SOLVED: To provide waste heat recovery equipment that can efficiently utilize a sensible heat of a blow-down exhaust gas pulled out from a dust collection hopper of a dust removal machine when the blow-down type is used as a dust removal machine for recovering waste heat and is used in a sintering machine system. <P>SOLUTION: The waste heat recovery equipment 4 used for a sintering ore cooling device 3 of sintering machine system 1 includes an exhaust duct 43 to which a high-temperature exhaust gas produced in the first half section of the sintering ore cooling device 3 is guided, a blow-down type dust removal machine 44 which is provided in the exhaust duct 43 and includes an inertial dust remover or a centrifugal dust remover, a boiler 45 which collects an waste heat of an exhaust gas wherein dust is removed by the dust removal machine 44, a heat supply duct 47 which introduces a blow-down exhaust gas having a sensible heat pulled out from a dust collecting hopper 44a under the dust removal machine 44 to an ignition furnace 12 of a sintering machine 2, and a dust collecting machine 48 and a fan 49 which are provided in the heat supply duct 47. In addition, the waste heat recovery equipment also uses the blow-down exhaust gas as a combustion air of the ignition furnace 12 or a preheating air of fuel. <P>COPYRIGHT: (C)2013,JPO&INPIT |
