Question

500 MW Medupi power station generates electricity using coals of calorific value of 4890

kcal/kg. The thermal and electrical efficiency of the power station are 22.1% and 87.4%, respectively. 

Instructions:round off to 2 decimal places 

1. Determine the overall efficiency of the power station (%) .And  Determine the electrical energy produced per hour (kWh) 

2. Determine the heat of coal combustion per hour (kcal) .And Determine the amount of coals consumed per hour (tonnes) 

3. Determine the amount of coals consumed per day if the daily load factor is 55%. (tonnes) 

4. Determine the percentage savings of coal weight if the calorific value increases by 4% when purchasing new advanced coal.
