| Summary: | Geothermal energy conversioninto electricityatGeoDipa Energy Ltd Dieng
power plant use steam from the earth to rotating the turbine.Steam produced in
PLTP GeoDipa EnergyLtd. Dieng�s wells has wet characteristic. So it, needs to
separatethe vapor phase from mixed phaseon theseparator.
Steamproducedfromgeothermal wellscontainingnon condensable gases. Non
condensablegaseswillgivenegative impactin the condenser. Non condensable
gasesshould beremoved because willraise thecondenserpressureanddecrease
thegeothermal power plant system eficiency.
Cycle Tempo simulation result is verified with PLTP Geo Dipa Energy Ltd
Dieng�s operation data. From result verification, the difference between steam
entering PLTP is 0.004 %. The other variabel verified is cooling water mass flow
rate entering main condenser and nett power generated. The difference of both is
1.45 % and 2.875 %. In this research, initialcondenserpressurewas
variedtodetermine ejector operating effectto power plant system eficiency.
Condenserpressurewas variedfrom0.05 bar-a to 0.1bar-a barwith range per
0.01bar-a. Power plant system eficiency is comparation between nett power
generated and maximum power rate entering power plant system, with126.3 MW
maximum powerrate entry geothermal power plant. Theoptimal condenser
pressureobtainedat0.07bar-a with 19.51 % system efficiency. |
