Pengaruh Low Pressure (Lp) Control Steam Terhadap Efisiensi Turbine Unit 7
The steam power plant system is a system of generating electrical energy from converting steam energy produced by water heated in the boiler to produce steam. Then the steam goes to the turbine so that it rotates the turbine rotor and rotor on the generator to produce electrical energy. The definition of turbine efficiency is the ability of the turbine to convert the heat energy contained in th…
