ORC SYSTEM WITH 2 STAGE RADIAL TURBINE

摘要

PURPOSE: An ORC system with a 2 stage radial turbine is provided to increase the efficiency of pressurizing working fluid at a condenser by additionally lowering the temperature of working fluid by passing through a 2 stage centrifugal turbine. CONSTITUTION: An ORC system with a 2 stage radial turbine comprises a generator housing(10), a first turbine housing(20), and a second turbine housing(30). The first turbine housing comprises a first inlet(22), a first turbine nozzle(23), and a first outlet(24). The first turbine nozzle injects working fluid flowing into the first inlet to a first turbine blade(21). The first outlet is formed on the rear side of the first turbine blade to discharge the working fluid. The second turbine housing is composed of a second inlet(32), a second turbine nozzle(33), and a second outlet(34). The second turbine nozzle injects the working fluid flowing into the second inlet to a second turbine blade(31).
