Abstract (en)
[origin: EP2664847A1] Areliable and cost-effective boiler equipped with a sound air supply nozzle which enables the following is provided: even when there is a gap between the nozzle provided in a through hole communicating with the interior of a furnace and the through hole, a strong swirl flow along the inner surface of the furnace wall can be formed; and burnout due to radiant heat can be suppressed. The air supply nozzle has the through hole in the furnace wall comprised of a water pipe, the nozzle supplying air is inserted into the through hole, and there is the gap between the nozzle and the through hole. The air supply nozzle is so configured that the position of the tip of the nozzle is located at a distance of 0.8 times the nozzle inside diameter or more away from the furnace wall inner surface and a tangential velocity component is given to gas jetting out of the nozzle.
