<p>PROBLEM TO BE SOLVED: To enable full operation of heat source equipment even when periodic inspection of waste heat recovery boilers is taken into account, by providing the waste heat recovery boiler for each of a plurality of branch flues branching from the outlet of a main flue leading out waste gas from a heat source. SOLUTION: This waste heat recovery system comprises a blower 3 and an air duct 4 for sending air to a heat source 2, a main flue 5 for leading out waste gas from the heat source 2, a first flue 7 and a second flue 8 branching off in two from the outlet 6 of the main flue 5, a first waste heat recovery boiler 10 provided for the first flue 7 and a second waste heat recovery boiler 40 provided for the second flue 8. A first inlet damper 20 and a first inlet shielding mechanism 30 are provided for the first flue 7 so that the first inlet damper 20, the first inlet shielding mechanism 30 and the first waste heat recovery boiler 10 are disposed in this sequence, while a second inlet damper 50, a second inlet shielding mechanism 60 and the second waste heat recovery boiler 40 are provided for the second flue 8 in this sequence.</p> |
