Abstract

650,064. Axial-flow compressors; gas turbine plant. AKT.-GES. BROWN, BOVERI, & CIE. Feb. 10, 1948, No. 3850. Convention date, Oct. 22, 1947. [Classes 110(i) and 110(iii)] The blades of at least the first stage of an axial-flow compressor are de-iced by passing gaseous medium at a sufficiently high temperature over the blades in the form of a film which constantly renews the boundary layer. In a gas turbine plant, part of the exhaust gases from a turbine 3 are passed by way of at least one pipe 8 to guide blades 7, and by way of hollow rotors 10, 11 to rotor blades 9 of a compressor 1. The gases pass through the blades 7, 9 by way of slits connected with longitudinal channels. The gases may be taken from an intermediate stage of the turbine. Alternatively, air from a later stage of the compressor may be used. In the case of a compressor forming part of a steam or gas turbine plant in which the turbine blades are protected by a film of cooling medium, e.g. compressed air, this medium may be used for heating the compressor blades. Specifications 347,374, 524,794 and 531,445 are referred to.
