    摘要: A tubular type heat exchanger unit which utilizes upper inlet (12) and outlet (22) headers which are connected to at least three lower headers (14,16,18,20) by multiple elongated vertically-oriented U-shaped tubes (17). The U-shaped tubes are provided in adjacent banks and rows within a thermally-insulated casing. Preferably 4-12 lower headers each having a bank of 4-20 vertical tubes are provided. Such heat exchanger unit is enclosed within a thermally-insulated and is suitable for use as an economizer and superheater in heat recovery steam generators (HRSG).

    摘要: In a multi-tube once-through boiler, a structure is obtained in which recovered oil and waste solvent can be used as combustion gas for generating consumed steam and cleaning of water tubes can be performed easily.
    In a multi-tube once-through boiler configured such that boiler water within water tubes is heated and evaporated to take out consumed steam, a combustion chamber (9) has a horizontally extending cylindrical shape, each water tube has an arc shape arranged on left and right sides of the combustion chamber (9), rows of water tubes arranged on the left and right of the combustion chamber (9) are respectively connected by linear left and right upper headers (1) provided at upper ends and linear left and right lower headers (2) provided at lower ends, a lid body (door) (22) is formed on one end side facing the combustion chamber (9) and a burner (10) for supplying combustion gas to the combustion chamber (9) is provided, and the burner (10) is provided with a recovered oil supply unit for supplying recovered oil, a waste solvent supply unit for supplying a waste solvent, an injected air supply unit, a combustion air supply unit, and a control unit for controlling the supply of the recovered oil, the waste solvent, the injected air, and the combustion air.
