Screw expander tested on COMOTI bench and at beneficiary
Journal Title: Jurnalul Stiintific TURBO - Year 2017, Vol 4, Issue 2
Abstract
National Research & Development Institute for Gas Turbines Comoti has developed a helical screw expander - asynchronous electric generator assembly – as well as a test system for tracking the parameters of thermal, mechanical and electrical processes during common or transitory working regimes, their adjustment and control in order to ensure maximum security working conditions. The element of novelty of this electric energy providing assembly constitutes the use of a helical turbine that works at lower speed than other classical expanders due to the elimination of the reductor which ensures the connection of the expander to the electric generator. The monitoring system introduces functional check-ups of the manual and electrical operated elements as well as the check-up of measuring lines of the analog parameters. The testing was done in the testing bench at COMOTI premises and it used air as a working agent. The results thus obtained constitute the preliminary data that may offer the possibility of placing the screw expander - electric generator assembly inside regulating and measurement stations.
