PURPOSE: A hot air boiler is provided to improve combustion efficiency by successively burning combustion gas through a first combustion unit, a concentrated combustion unit, and first, second, third, and fourth re-combustion units. CONSTITUTION: A hot air boiler comprises a main body(1) and a hydrolyzing and supplying unit. The main body is composed of a vertical combustion chamber(A) and a horizontal heat exchange chamber(B). The main body temporarily stores combustion heat which is to be emitted to the outside and minimizes heat loss. The hydrolyzing and supplying unit is installed to be adjacent to a combustion unit(10) and decomposes water into hydrogen and oxygen molecules using combustion heat from the combustion chamber. |
