Title: Waste heat utilising district heating system - has exhaust gas moved by independent compressor
Inventor: STRACH LOTHAR
IPC: F02C1/04
Filed: 1977-04-26
Abstract: An addition to 610943 concerning the application of waste heat to preheat a gas turbine air circuit, proposes the use of an independently driven compressor to propel the hot exhaust gases to the place where they are required. The advantage gained in that a small dia. delivery pipe can be used. The compressor is located close to the exhaust gas output source and driven by an electric motor. The electric motor receives its energy from the remote generator turbine plant. Alternatively the compressor could be driven by a gas turbine compressor utilising the waste heat at the output source.
