For example, the heating water heated in the boiler is supplied to a heating pipe (not shown) connected to the heating export water pipe 102 to circulate and perform heating, and the heating water circulated along the heating pipe is heated. It is obtained through the return pipe 101 and is subjected to a circulation process obtained and heated into the boiler.

However, in the boiler, condensation due to temperature difference occurs in the vicinity of the heating and receiving pipe because the heating water flowing into the heating and receiving pipe is obtained in a relatively cool state after performing heating while circulating the heating pipe.

In particular, in the initial operation of the boiler, the low-temperature heating water stagnated in the heating pipe is obtained through the heat-receiving pipe, and the above-mentioned condensation occurs frequently. Such condensation causes corrosion of the boiler parts in the long term. There is a problem of shortening.

In addition, since the boiler forms a plurality of connections for improving the thermal efficiency, and the baffles must be assembled inside the connection, the boiler is inferior in workability and complicated in structure.

Therefore, the present invention provides a structure of the outer cylinder and the inner cylinder to form a boiler so as to prevent condensation caused by the cold heating water flowing into the boiler, and a structure of a heating and return pipe for introducing heating water into the tank inside the outer cylinder and the inner cylinder. The purpose is to provide a double water tank oil boiler that is easy to prevent and manufacture corrosion due to condensation.
