PURPOSE: A pellet boiler is provided to conveniently operate the boiler by facilitating the thermal power of the boiler and to obtain the stability of the boiler using a backfire preventing device. CONSTITUTION: A pellet boiler comprises a fuel storing unit and a boiler unit (2). The boiler unit sequentially positions a fuel injecting hole, a fuel sensor, a first backfire preventing device, and a driving motor from the right upper end in the inside to the lower end. A water tank, a second pass connecting pipe, a chain driving device, a connecting pipe cleaning device, a second backfire preventing device, a fire grate, a fire grate bottom, and an ash receiver are sequentially equipped from the upper end of a central part inside the boiler to the lower end. An exhaust pipe, a collecting water preheater, an absorbing heat plate, a water heat collecting unit, and a dust reducing device are positioned from the right upper end inside the boiler to the lower end. |
