  • the cleaning nozzles 1 are fixed to a number of air holes 16a, 16a, 16a, 16a ----formed in the inner wall 16, and the air holes 16a, 16a, 16a, 16a ---- each clogged with foreign materials are cleaned by reciprocably actuating the cleaning pin 8 for each of the cleaning nozzles 1.
  • reference numeral 18 denoted a nozzle driving portion having the cleaning nozzle secured thereto.
  • Fig. 17 is an enlarged sectional view which shows a driving portion for driving the cleaning nozzle usable for the apparatus for cleaning holes for a combustion furnace.
  • the cleaning nozzle driving portion 18 is composed of a cleaning nozzle 1, a securing frame 18a, a rotational gear 18c and an eccentric cam 18d.
  • a securing frame 18a is fixed to the inner wall 16 while coming in contact with the inner wall 16, and a rotational gear 18c and an eccentric cam 18d are arranged behind the cleaning nozzle 1.
  • Reference numeral 20 denoted a driving motor for rotating a chain 17.
  • a driving gear 21 is rotatably mounted on a rotational shaft of the driving motor 20, and the chain 17 is placed on the driving gear 1.
  • the chain 17 extends around the gears 18c, 18c, 18c, 18c ---- for the cleaning nozzle fitting frame 18, 18, 18, 18 ---- so that as the chain 17 recirculates, gears 18c, 18c, 18c, 18c ---- are rotated in operative association with eccentric cams 18d, 18d, 18d, 18d - ---.
  • a shaft 18e having the eccentric cam 18d mounted thereon exhibits a hexagonal sectional shape consists in that the cleaning nozzle can spirally be opened and closed, and moreover, air can freely be rotated. For example, similar to a washing machine, an air swirl for rightward rotation or leftward rotation can freely be generated.
  • each air hole can normally be cleaned, a sufficiently quantity of oxygen can normally be supplied to the combustion chamber, and a quantity of air to be supplied to the combustion chamber can adequately be regulated, a convectional flow can be generated in the combustion chamber, resulting in complete combustion being achieved. This is very favorable for an environment.
