PURPOSE: A top-down combustion type solid fuel boiler is provided to reduce smoke by reburning incompletely burned gas using air spray of a nozzle. CONSTITUTION: A top-down combustion type solid fuel boiler comprises a combustion chamber(1) in which solid fuel is burned, a water tank(2) which formed by filling water around the combustion chamber, a smoke stock(6) for discharging combustion gas to outside, a first nozzle assembly(20) comprising first through third nozzle parts(21,22,23), and a first blower(30). The first nozzle part is installed on the inner upper periphery of the combustion chamber. The second nozzle parts are communicated with the first nozzle part and vertically installed adjacent to the inner wall of the combustion chamber, and the second nozzle parts spray air eccentrically to the inner center line of the combustion chamber to form vortex. The third nozzle part is communicated with the second nozzle parts and sprays air to the inside of the combustion chamber. |
