In a Steam power plant, _________ heats the feed water on its way to the boiler by deriving heat from the flue gases.

A steam power station spends Rs. 30 Lakhs per annum for coal used in the station. The coal has a calorific value of 5000 kcal/kg and costs Rs. 300 per ton. If the station has thermal efficiency of 33% and electrical efficiency of 90%, the average load on the station is

A run of river hydro plant with pondage has the following data:

Water head = 20 m

Overall efficiency = 80%

Load factor = 40%

If an a particular day, the river flow is 20 m³/sec, the load factor of the plant is _____ (in %)

A generating station has a maximum demand of 25 MW, a load factor of 60%, a plant capacity factor of 50% and a plant use factor of 72%.

The maximum energy that could be produced daily if the plant while running as per schedule, were full loaded is ______

A power station has a maximum demand of 15 MW. The annual load factor is 50% and plant capacity factor is 40%. The reserve capacity of the plant is ______ (in kW)

Which of the following are the advantages of interconnected operation of power system?

1. Less reserve capacity requirement

2. More reliability

3. High power factor

4. Reduction in short circuit level.
