Power Plant Engineering for captive power plant

 

  In general heat rate is defined as ratio of heat input to power output in a system, in other way requirement of heat energy to generate one unit of power. In case of power plant cycle , output is electrical power and input is any kind of energy in fuel . If we consider steam turbine heat rate , input energy to turbine is in the form of steam energy i.e enthalpy corresponds to pressure and temperature. Different cases for steam turbine are considered as follows: Steam Turbine Heat Rate: CASE1: This is the calculation for closed cycle, single cylinder, condensing type of turbine where steam inlet to turbine at point no1 is expanded to point 2 as per below fig : Turbine Heat rate: M= Mass flow rate of steam inlet to turbine, kg/hr                                           ...
