Abstract

304,479. British Thomson-Houston Co., Ltd., and Collingham, R. H. Jan. 27, 1928. Casings. - In order to prevent "creeping " the casing of a turbine operating with elastic fluid at a very high temperature is made in two portions A, B, the portion B which is subjected to the very high temperature being under no tensile stress, but under compression stresses of negligible or low value only. This is achieved by circulating in the space between the casings A, B, fluid of the same pressure as, but of lower temperature than, that supplied by the nozzles N to the turbine in the casing B. The joint J, H between the casings is made tight, but a slight clearance is left in the joint C to allow heating fluid to leak away. The heating chamber is supplied through a connection E, and the turbine is separately supplied with superheating fluid to leak away. The heating from swivelling couplings G joined to supply pipes F. The internal casing B is lagged at O with non-conducting material.
