<p>Provided is a boiler that has a simple piping arrangement during installation and that can be made compact. A boiler (1) comprises: a vessel (10) that generates steam by a liquid being heated by way of burning a fuel; a water supply channel (20) for supplying the liquid to the vessel (10); an air supply channel (30) for supplying air for combustion to the vessel (10); an exhaust channel (50) by which combustion gas generated by the vessel (10) is discharged and that is disposed on the side of the vessel (10); an economizer (60) that is disposed in the exhaust channel (50) and that performs heat exchange between the liquid flowing in the water supply channel (20) and the combustion gas flowing in the exhaust channel (50); an air heater (70) that is disposed further downstream than the economizer (60) in the exhaust channel (50) and that performs heat exchange between the air for combustion flowing in the air supply channel (30) and the combustion gas flowing in the exhaust channel (50); and a blower (80) that is disposed near the air heater (70) and that sends air for combustion to the air supply channel (30).</p> |
