Theoretical indicator diagram for a steam engine is shown in Figure 5.3 without clearance volume and with clearance volume in Figure 5.4. In Figure 5.3, clearance volume is zero. Steam at boiler pressure enters into the cylinder at point 1 and cut-off at point 2. Then the steam expands inside the cylinder isothermally from point 2 to point 3. Point 3…

A steam engine is a reciprocating heat engine that performs mechanical work by using steam as its working fluid. Steam engines are external combustion engines based on modified Rankine cycle, where the working fluid is separate from the combustion products. Water is heated in a boiler until it reaches a high pressure and temperature (superheated…

Steam power system is a system in which the heat energy of the steam is used to produce mechanical power. Various types of fuels (coal, diesel, natural gas, geothermal, nuclear, etc.) are used to produce the high quality of steam, i.e., superheated steam and then the thermodynamic expansion process is used to convert the heat…
