Abstract

179,493. Robertson, T. E., (Power Specialty Co.). Nov. 26, 1920. Superheating-tubes with external ribs.-In apparatus applicable generally for effecting exchange of heat between two fluids, a fluid is passed through a system of pipes over which furnace gases sweep, and the pipes are provided with protective-casings, the heat transmitting capacities of which are least near the furnace where the gases are hottest, and are greater in the region where the gases are cooler. The casings consist of corrugated rings 2, Fig. 1, threaded on to the tubes 1, and the heat-transmitting capacity is varied by varying the depth number or thickness of the corrugations or the thickness of the body portion of the casings. In the form of apparatus shown in Fig. 4, in which the fluid passes from an inlet 18 to an outlet 20, through banks of tubes 16, 17 heated by gases from a combustion chamber 12 which pass upwards over the bank 16 and downwards over the bank 17, the tubes are provided with corrugated casings which have shallow corrugations in the hottest region 21, and the depth of the corrugation increases progressively in the successive rows or tubes to the coolest region 22.
