Unlike a conventional pellet boiler having a pellet feeder, a conventional feeder boiler (or a wood boiler) needs to supply only one amount of wood to be used once, and once again, when the wood is burned, There is an inconvenience that it is necessary to check the consumption amount and supply it.

In addition, the pellet boiler burns the pellets in the combustion chamber inside the combustion chamber. Since the pellets are small particle fuel, the space inside the combustion chamber is narrowed. Pellet boilers were forced to use only pellets as fuel.

In other words, conventionally, a harmony boiler and a pellet boiler have been developed and used respectively. The user had the inconvenience that the fellowship boiler had to use the firewood (wood) only as fuel and the pellet boiler had to use only pellets as fuel.

In addition, firewood is relatively easy to obtain and low-cost fuel, and pellets can be supplied automatically by the pellet feeder.

Therefore, it is inevitable to develop a boiler which can selectively use the fuel desired by the user in the harmony or the pellet while using all the harmonics or pellets as the fuel.
