Q 1. What are the methods of prediction of future load.
Q 2. What are the two methods to find the composition of solid fuels.
Q 3. What aspects should be considered while selecting a fuel for power plant.
Q 4. The percentage composition by weight of a sample of coal is as follows
C = 65.50% O2 = 17.50% H2 = 6.65% S = 1.80%
Using the Dulong's formula, calculate the calorific value of coal.
Q 5. Explain the working of a pumped storage power plant. Explain a few setups in which pumped storage power plant is used as peak load power plant.
Q 6. The percentage composition by weight of a sample of coal was found to be as follows
C = 24% O2 = 8% H2 = 5% Ash = 63%
and it was observed that the dry flue gas has the following composition by volume CO2 = 10% CO = 2% O2 = 13% N2 =75%
