ME 8792 POWER PLANT ENGINEERING  ENGINEERING QUESTION BANK UNIT-I 2-marks

1. What do you understand by the term boiler draught? (AU Nov/Dec 2016)

Boiler draught may be defined as the small difference between the pressure of outside air and that

of gases within a furnace or chimney at the grate level, which causes flow of air/hot flue gases to

take place through boiler.

1. Define steam rate and heat rate? (AU Nov/Dec 2016)

Heat rate is the common measure of system efficiency in a steam power plant. It is

defined as “the energy input to a system, typically in Btu/kWh, divided by the electricity

generated, in kW.” Mathematically:

1. What are the different sources of energy available for power generation? How long they

can last? (AU May 2014)

1. Steam
2. Gas or air
3. Diesel and petrol
4. Nuclear
5. Renewable energy sources such as solar, wind ,geothermal, tidal, wave, MHD etc
6. Why thermal plants are not suitable for supplying fluctuating loads?(AU (EEE) May 2014)

Thermal plants are not suitable for supplying fluctuating loads because any change in load

demand requires the corresponding change in the output energy. In thermal power plants, the

input energy is produced by burning the coal. So, there is always a large time lapse between the

change in energy output and input which is not desirable. Therefore, such power stations are used

only as base load stations and it supplies the constant power.
