Consider a coal-fired steam power plant that produces 175 MW of electric power. The power plant operates on a simple ideal Rankine cycle with turbine inlet conditions of 8 MPa and 560°C and a condenser pressure of 8 kPa. The coal has a heating value (energy released when the coal is burned) of 29,300 kJ/kg and a CO2 emission value of 0.093 kg CO2/MJ. Assuming that 85% of this energy is transferred to heat in the boiler and that the...

A coal-fired steam power plant produces 175 MW of electric power. The power plant operates on a Rankine cycle with turbine inlet conditions of 7 MPa and 550oC and a condenser pressure of 15 kPa. The turbine efficiency and pump efficiency are both 0.8. The coal has a heating value (energy released when the fuel is burned) of 29,300 kJ/kg. Assuming that 85 percent of this energy is transferred to the steam in the boiler and that the electric generator...

When coal is burned in a power plant, it releases approximately 30 kJ of energy for every gram of coal that undergoes combustion. A percentage of the energy is used to generate electrical power, and the rest of the energy is lost as heat. Determine the amount of energy used, in joules, of a 40.0 W light bulb that is left on for 1.70 h. energy Determine the amount of electrical power, in watts, generated by a circuit that uses...
