Consider a boiler plant consisting of an economizer, a boiler and a super heater Mass of water evaporated per hour=5940Kg/hr
Mass of coal burnt per hour=675 Kg/hr
L.C.V of coal=31600 k J/Kg
Pressure of steam at boiler stop valve=14 bar
Temperature of feed water entering and leaving economizer=32°C and 115°C resply
Dryness fraction of steam leaving boiler and entering super heater=0.98
Temperature of steam leaving super heater=260°C
Specific heat of superheated steam=2.3 K J/Kg, determine
1. Percentage of heat in coal utilized in economizer.
2. Percentage of heat in boiler.
3. Percentage of heat in coal utilized in super heater.
4. Overall efficiency of boiler plant.
