摘要
A heat recovery device of a boiler is provided to not to affect the ventilation of the exhaust gas since the exhaust gas passes through an inner space of a coil. A heat recovery device of a boiler comprises a first pipe(20) and a second pipe(30). The first pipe adheres closely to a cylinder inner wall, increase the water in the lower part of the cylinder up in order to make the water connect the heat of exhaust gas of cylinder rim. The second pipe forms a coil with smaller diameter than the one of the first pipe, is consisting of a plurality along the inner longitudinal direction of the first pipe. The hot water on the lower part of the cylinder is discharged by contacting the water flowing in through the first pipe and the heat of the exhaust gas of cylinder central part.
