What is the role of burning coal in an electrical power plant?
The heat is converted to electricity by a thermocouple.
The heat boils water.
The light from coal burning is converted to electricity by a photovoltaic panel.
The heat produces a rush of wind which turns a turbine.
The expansion of gases caused by burning coal makes pistons turn in an internal combustion engine.
Heat from coal is used to boil water which in gaseous state(steam) is at high Temperature and pressure makes the turbine to turn.
So, correct answer is optionB
What is the role of burning coal in an electrical power plant? The heat is converted...
A power plant produces electricity by burning coal and converting water into steam. The pressurized steam makes a turbine turn, which produces electricity. The plant has a power output of 380 MW and operates at an overall efficiency of 31%. How much coal does the plant burn in one minute (60 s)? State your answer in kilograms. (1 kg of coal yields 30 MJ energy)
A typical large coal fired electric power plant produces 1,200MW of electricity by burning fuel with energy content of 3,000 MW. Three hundred and forty (340) MW are lost as heat up the smokestack leaving the rest to drive a generator to produce electricity. However, the thermal efficiency of the turbine is only 45%. That is 45% of the remaining power goes to drive the generator, and 55% is waste heat that must be removed by cooling water. Assume that...
