Abstract:
Development of power plants is one of most important studies that may be heuristically in the field of power engineering department, where these studies aimed at developing stations by reaching for ways to increase performance and reduce the cost of the plants.
From this upstream we conducted our research in this field and chose us as a model of Garri power station (4) which operated by steam turbine and boiler type CirculatingFluidized Bed (CFB).
The importance of our project is to study the effect of high pressure heat exchangers in raising the efficiency of the steam turbine generating stations, thus increasing the productive capacity and supplying the national network with a current that meets the consumer's needs. On the other hand, it reduces the vibrations in the turbine shaft and increases the operating life of the steam turbine station. High pressure heaters are of great importance in increasing the operating life of the boiler type by reducing the voltage exerted by the absence of high pressure exchangers.
Through our study, we followed the calculation of the ratio of the amount of heat added in the presence of thesehigh pressure heat exchangers and lack of presence and which are more effective in increasing efficiency and calculating the impact of each of them we have concluded that heat exchangers high pressure oils have the effectiveness in increasing the generating capacity so the efficiency increased from (31.6%) to (36.6%) .
We have also made a simulation of the movement of Belding from turbines to high pressure heaters and their impact on turbine shaft, efficiency and general simulation of the water and steam cycle of Garripower plant.
