Definitions

  • One embodiment of last mentioned type includes a sleeve which is displaceable towards and away from the passage and which directs a stream of air branched off from the volume of air alloted to the pertaining passage. so it is forced to flow along the walls of the passage.
  • a device of this type will show fine cleaning results, but it suffers from two disadvantages.
  • passages are, depending upon the type and the size of the furnace, combined into registers for the supply of primary and secondary air, respectively.
  • the passages are, in connected to conduits I3 supplying preheated air.
  • FIG. 3 shows a first modification of the device.
  • the sleeve 14 is. here by means of a bellows 30, connected to the back wall of the air conduit 13:: and is carried by a support 31, which runs in a guide means 32. This is. in turn. carried by a bracket 33 within the air conduit 13.
  • the screw 19 is connected with the support 31 and can. in the same manner as described in connection with the previous embodiment. displace the sleeve to wards and away from the opening 15.
  • the bellows makes these movements possible without any air leaking into the sleeve from the surrounding air conduit.
