Definitions

  • a chimney according to the invention has at the top part of its central duct a bunch of water tubes which communicate at one end with the channels in the hollow side walls and which have their other ends associated with a collector reservoir or tank or the like communicating with the last-mentioned channels and disposed at the periphery of the exit orifice of the central duct, such reservoir or tank or the like extending the walls which bear it.
  • the tubes of the bunch are inclined and start at the channels of one wall to extend to that part of the collector tank which is disposed on the opposite wall; also, consecutive tubes of the bunch are inclined alternately in opposite directions.
  • a chimney comprises hollow side walls, as 2-5, which bound a central duct or passage or the like 6.
  • the hollow side walls have channels in which there is a ilow of cooling water i the direction indicated by arrows X, while hot gases ow through the central duct or passage 6 in the direction indicated by an arrow Y.
  • Slightly below the exit aperture 7 which can be lateral instead of central-two opposite side walls, for instance, the walls 2 and 4, have internal projections 2a, 4a respectively.
  • Inclined tubes 8 have their bottom ends 8a communicating with the 3,233,595 Patented Feb.
  • inclined tubes 11 have their bottom ends 11a secured to the bottom projection 4a while their top ends 1lb engage in the cross-tube 12 and just rest on the top projection 2b; the tube 12 is connected through vertical tubes 13 to that part of the reservoir 10 which communicates with the wall 2 opposite the wall 4. Tubes 1l alternate with tubes 8, and some of the cooling water fiows from the wall 4 through the tubes 11-13 into the tank iii. The same is connected to the base of the chimney through vertical ducts 14 through which the water i'lows to the base region of the chimney.
  • the collecting tank 10 extends to side walls which bear it. Disposed at the levels of the projections 2a, 4a and 2b, 4b are outside collars 16, 17 which form clamping belts or straps or the like to take up horizontal thrusts at the levels where the two crossed tube bunches are supported. Fitted to the tank 10 are mechanical water and vapour separators, 15, the water returning to the tank 10 while the dry vapour is removed to atmosphere.
  • a chimney of the kind hereinbefore described has the great advantage of providing considerable heat exchange by convection immediately before the gas exit.
  • a cooled chimney for steel making converters having hollow side walls with water channels constituting a central duct for the passage of the gas to be cooled, a bunch of water tubes in said central duct, a reservoir tank located at the top of said hollow side walls and surrounding said central duct, a vapour separator on said reservoir tank, said water tubes communicating at one end with one side wall and at the other end with said reservoir tank, said water tubes being inclined and starting from one of said side walls for terminating in that part oi the reservoir tank located on the opposite wall, said reservoir tank being directly supported by said side walls, bottom projections on the inside surfaces of said side walls for receiving the water tubes bottom ends, a collector tube receiving the water tubes top ends, top projections on said inside surfaces tor supporting said collector tube communicating with said reservoir tank, and external clamping collars on said side walls at the levels of said bottom and top projections for taking up the horizontal thrusts of said water tubes.
