<p>The present invention relates to a pellet boiler capable of reducing pollution of an ambient environment by discharging combustion heat after cooling. The boiler of the present invention is capable of improving a combustion efficiency of the boiler by transmitting the combustion heat absorbed by an absorbing fan (119) to a second housing (111) through a first housing to preheat and supply cold water. In addition, the boiler of the present invention is capable of discharging the combustion heat discharged through the nozzle at a state of being cooled by enabling the combustion heat to be in contact with a surface of the cooling water to primarily cool the combustion heat, and passing the primarily cooled combustion heat through a discharging passage (129) to secondarily cool the combustion heat.</p> |
