The present work is devoted by an experimental study for an important parameters to increasing the thermal and internal efficiency for a steam power plant by reducing the condenser pressure, but there is a problem in condenser performance which is, air inter to inside condenser prevents it to continue with the same production. The experimental work was conducted using the steam power plant (Didacta- Italia) made in the university of Damascus/ syria .This study aim to (1) Reducing the condenser pressure to increase the thermal efficiency, (2)The condenser efficiency must be constant with time by suction of air collection inside the condenser to make the quantities of air (inside and outside) is equal. By Reducing the condenser operating pressure to (0.45 bar, 0.40 bar, 0.35 bar, 0.30 bar, 0.25bar) with all the other parameters are constant. A computer program (Fortran 90) was used . After the measurements and calculations for each state of reduced condenser pressure were given , the thermal efficiency increased by ratio 4.3% and the internal efficiency increased by ratio 2.1 % when the condenser pressure reduced to 0.25bar. Also, the max. efficiency of condenser was 80.09 % with constant production by the continuo of air suction .The results are represented graphical and discussed. The inclusions dependent on the results of this study.
