A. increases with the increase in number of stages
B. decreases with the increase in number of stages
C. remains same irrespective of number of stages
D. none of the above

Base Load and Peak Load power plants
Power plants are categorized as base load and peak load power plants.
Base Load Power plants:
Plants that are running continuously over extended periods of time are said to be base load power plant.
The power from these plants is used to cater the base demand of the grid. A power plant may run as a base load power plant due to various factors (long starting time requirement, fuel requirements, etc.).
Examples of base load power plants are:
Peak Load Power plants:
To cater the demand peaks, peak load power plants are used. They are started up whenever there is a spike in demand and stopped when the demand recedes.
Examples of Peak load power plants are:
Belt conveyer can be used to transport coal at inclinations upto____________?
A. 30°
B. 60°
C. 80°
D. 90°
Under-feed stokers work best for _________ coals high in volatile matter and with caking tendency?
A. anthracite
B. lignite
C. semibituminous and bituminous
The proper indication of incomplete combustion is_______________?
A. high CO content in flue gases at exit
B. high CO2 content in flue gases at exit
C. high temperature of flue gases
D. the smoking exhaust from chimney
Load curve is useful in deciding the__________?
(a) A. operating schedule of generating units
B. sizes of generating units
C. total installed capacity of the plant
D. all of the above
Caking coals are those which__________?
A. burn completely
B. burn freely
C. do not form ash
D. form lumps or masses of coke
