PURPOSE: A firewood boiler is provided to completely use thermal energy to heat-exchange by inducing perfect combustion while processing third combustion in a combustion chamber. CONSTITUTION: A firewood boiler comprises an outside housing(100), a combustion chamber(400), a blower(250), a first heat exchanging chamber(500), and a second heat exchanging chamber(600). The first heat exchanging chamber comprises a connection pipe of the combustion chamber, a hot water pipe, a plurality of vertical branch pipes(531), and a vertical merge pipe(533). The vertical branch pipes are arranged while being separated from each other to the vertical direction. Combustion gas moves in the vertical branch pipes. The vertical merge pipe is connected to the bottom of the second heat exchanging chamber by merging the plurality of vertical branch pipes. |
