Abstract
Because peak electric demand for many utilities occurs in the hot summer months, a traditional combustion turbine installation is at a disadvantage summer peak operation. When a utility need electric generating capacity most , the combustion turbine’s capacity is at its lowest level. However, high atmospheric temperatures cause reductions is net power output of gas turbine power plants.
In the present work, description and analysis of the use of absorption Li-Br cooling system to enhance the performance of the Hurghade gas turbine plant throuh the improvement of inlet parameter are carried out. Also, an economical evaluationfor the proposed system has been carried out. The plant consists of five General Electric gas turbines, each of them has a rated power of 25 MW, In the proposed system, the cooling system is activated by heat recovered from the turbine exhaust.
A computer simulation that provides calculationof the performance of the plant is presented. Monthly values of the net power output, heat rate of the plant as weel as performance of the cooling system are given with the corresponding weather conditions. When ambient air is cooled to the correspondingdew point temerature,power enhancement of about 10 % can be realized in june.
Results of the simulation model show that the percentage enhancement of the power depends on the weather conditions. The results of the present analysis validated the advantages of the gas turbine congeneration with absorption air cooling.
Results of the economical study show that a payout period of about 3.28 year is expected when absorption cooling system is applied for inlet air cooling purpose.
