A coal-fired power plant is burning bituminous coal that has an energy content of 12,000 Btu/lb. The power plant is burning the coal at a rate of 110 lb/s. The efficiency of the powerplant is 33%, which means that 67% of the total energy from the coal is lost as waste heat. a. A new heat exchanger is installed that is capable of using 0.12% of the waste heat to heat an air stream for use in another process in...

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...

On a cold day, my home furnace consumes one million BTU of heat energy from natural gas. a) How many hundred cubic feet of gas (ccf) are needed in one day? This is the unit used on your monthly bill. b) Some of the heat energy is lost through the chimney stack, with only 80% useful to heat the house. How many BTU is that loss? How many Joules? What eventually happens to the heat NOT lost up the stack?...

You are assigned to help an aged 30% efficient 800-MW coal-fired power plant in Indonesia. You learnt that a warning has been issued to this power plant demanding that the rate of SO2 emission from this power plan has to be reduced to no more than 0.6 kg s. You find out that every million BTU of heat supplying into this aged plant emits 0.8 lb of SO2. Since this power plant is aged, its power generation can be easily...

1. Steam power plant (a) The boiler of a power plant operates at a maximum temperature of 750oC. The condenser of the power plant draws in cooling water at 20oC. What is the theoretical maximum efficiency of the plant? (b) Now suppose that a real power plant is built to have an efficiency that is 80% of the theoretical efficiency. The power plant needs to generate 1GW (giga-watt) of power. How much energy (per second) needs to be supplied by...

Case problem 5 : Duke Energy Coal Allocation*
Duke Energy manufactures and distributes electricity to customers in the United States and Latin America. Duke recently purchased Cinergy Corporation, which has generating facilities and energy customers in Indiana, Kentucky, and Ohio. For these customers Cin- ergy has been spending $725 to $750 million each year for the fuel needed to operate its coal-fired and gas-fired power plants; 92% to 95% of the fuel used is coal. In this region, Duke Energy uses 10 coal-burning generating plants: five located inland...
