The Testing Projects of Electric Power Production from Geothermal Energy of the Radial-Inward Turbine Generator with nC4H10 as Working Fluid

Abstract

The testing f l u projects of binary cycles use a sed of organic nature n e r a t e power is achieved at the Geothermal Testing Station of Province Research Institute Energy China i n working fluid is evaporated to a temperature of by geothermal heat through a heat exchanger, it then expands in a turbine which drives a and i s condensed i n a condenser, releasing heat t o a cooling system i n which cooling water has a tempera- of to be pumped again i n the evaporator. An axial flow steam turbine generator is installed i n system for comparison with each other. The designed capacity of the each generator i s 100 . This paper detalled the testing project of the radial-inward turbine Its relative inner efficiency is and its maximum capacity come8 t o The energy efficiency of the system i s
