Definitions

  • An open cylinder 2 is arranged for the insertion of the wood chips into the boiler.
  • the cylinder is provided at the top with a flange 1, which is arranged on some appropriate support to hold up the cylinder in suitable position in relation to the feeding hole of the boiler.
  • An encircling pipe 3 rests on the flange, which pipe is joined to a certain steam source situated outside the boiler. From said pipe 3' six smaller pipesa, 5 which pass through the flange go downwards, and open out inside the cylinder atdifi'erent levels. The lower parts of the pipe are bent in the same direction in such a way that the jets of steam are directed slantingly downwards. The pipe, if one so desired it, could naturally be altogether arran ed inside the cylinder. 7
  • E lie wood chips fed to the cylinder are carried by the jets of steam and hurled by these in whirling motion down into the boiler.
  • 'llhe invention is not limited to cellulose boilers but may also be used for other devices for similar purposes.
  • a method for charging cellulose boilers and the like characterized in that the charge is inserted into the boiler by means of steam which is forced into it.
  • a device for charging cellulose boilers and the like consistingL of a cylinder adapted to be joined to the oiler, a pipe for supplying steam, and other pipes opening at one end into the cylinder and at the other end communicating'with the steam-supplying pipe.
  • a device characterized thereby, that the pipesopen in slanting direction downwards at different levels in the cylinder.
  • a device characterized in that the cylinder is provided at the topwith a flange ada ted to carry the cylinder, and that on this ange a steam pipe is arranged from which the pipes opening into the cylinder go.
