Abstracts: According to today’s scenario many hopeful means of generating electricity have been developed like biogas, solar cells, natural gas etc., but then also steam power plants will continue as a prime mover in the field of generating electricity. The reason behind this is that use of water as the main working fluid which is very abundant in nature and can be used further i.e. recycled so cost-wise it is least in comparison to any other means. Hence, most of the electricity being produced throughout the world today is from steam power plants. Steam power plants have many components like boiler, turbine, generator, condenser, cooling tower etc., in which condenser can be taken as one of the key component of steam power plants. The efficiency of plant depends upon the efficiency of condenser. So, to increase efficiency of steam power plant we have to carefully investigate parameters that affect condenser of plant. The conventional steam power plant works under the Rankine Cycle. In which the steam condenser act as a heat sink and the steam boiler act as a heat source have the same importance for the power plant operating process. Energy efficiency of the any power plant strongly depends on its turbine-condenser system operation mode. Operating the condenser at optimum circulation water flow rate is necessarily important to ensure minimum operating cost and maximum efficiency of the plant. To control the condenser variables like cooling water flow rate, condenser pressure, condenser temperature having vital importance on entire plant performance. For the given power plant configuration, cooling water temperature and/or flow rate change generate alterations in the condenser pressure. Those changes have great influence on the energy efficiency of the plant. Similarly boiler pressure and exit temperature of boiler have an effect on plant efficiency. In this project parameters that affect steam condenser of steam power plant will be carefully evaluated.
