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.

摘要： An economizer having a structure capable of efficiently warming water and facilitating inspection and cleaning is obtained.
In an economizer for warming water by combustion exhaust gas generated by a boiler, to a cylindrical water pipe (11) in which an inflow port (12) and an outflow port (13) are formed on a side surface and through which the water passes, a plurality of gas pipes (61, 62, 63) erected for circulating the combustion exhaust gas are arranged in corresponding fan-shaped portions of the water pipe (11). The combustion exhaust gas introduced from a bottom surface side of the water pipe folds back at an upper part of the water pipe and flows downward, then folds back at a lower part of the water pipe, flows upward, and flows out from an upper surface side of the water pipe, whereby the plurality of gas pipes efficiently warm the water in the water pipe (11).
