PURPOSE: A portable steam-circulation boiler is provided to reduce fuel consumption because a gap between a body and an air bladder is reduced to use a small amount of water required for the operation of the boiler. CONSTITUTION: A portable steam-circulation boiler comprises a body (10), a ring (20), an air bladder (30), a connection part (40), and a water storage part (50). The ring covers the lower part of the body to prevent heat from climbing up the outer surface of the body. The air bladder is separated inward from the body to store fluid to be heated and comprises a first protruded part (31) and a second protruded part (32). The connection part comprises a first bolt (41), a second bolt (42), and a steel use stainless (SUS) ball bearing (43). The water storage part is coupled to the connection part and comprises a groove (53) to which the second bolt is coupled so that water can be introduced into the body. |
