[Class 34 (i).] Relates to apparatus comprising stages, A<1>, A<2>, .. of steam heated cylinders for drying cloth, paper, &c., wherein between each two stages a vessel as f<1> is arranged in which some of the water of condensation from the first stage is allowed to revaporize owing to both the lower pressure in the succeeding stage and the sudden expansion in the vessel, and consists in removing the remaining water of condensation in the vessel f<1> by a waterleg g, h or other form of U-tube, which permits the condensate to flow by gravity while preventing the steam from following the same path, the water-leg being of greater depth than the head due to the maximum pressure difference between the inlet and outlet of the water-leg. Steam is supplied to the two stages by the manifolds b<1>, b<2>, and exhausted by the manifolds e<1>, e<2>. A byepass t may be fitted round the vessel f<1> either for warming the cylinders A<2> before operating, or for varying their pressure. A vacuum may be maintained by a pump m, in the stage A<2>, to overcome the tendency of the water to be retained by the centrifugal force, the exhaust being passed to the vessel f<2>. Or the exhaust may flow directly to the vessel f<2> through valve v<1>. Any steam passes out at s, and water from vessel f<2> passes, with water from vessel f<1>, respectively by tubes k, j to the hot-well.
