| 摘要 |
The present invention relates to a heat exchanger having an anti-soot structure for a boiler burning wood pellets to heat water that can improve the efficiency of heat exchange, minimize production of soot, and easily discharge the soot collected below the heat exchanger, by modifying the structure of heat-exchanging the water and the hot gas generated by combustion of the pellets in a burner. The heat exchanger includes a stovepipe connected to the burner and formed with a cutaway portion at a lower portion; a water chamber enclosing the outside of the stovepipe; a superheater installed in the stovepipe, with both ends of a penetrating pipe being opened, in which the outside of the penetrating pipe is enclosed by a casing, and the inside of the casing is connected to the water chamber by at least one support pipe to allow the water to freely flow; and a discharge unit installed below the cutaway portion of the stovepipe and discharging the soot by a rotating screw. |
