CHM310H1 Lecture Notes - Lecture 14: Fuel
Document Summary
Lecture 14: heat engine, power plant and issue with electricity. The efficient of a heat engine is its ability to take heat and convert it into work; the difference between the hot and the cold relative how much heat in the hot reservoir. qh qc qh. Plug ,themaximum energy whichaheat engine convert heat work ,efficiency=1 . Traditionally, you have a boiler; you burn your fuel below the boiler, heat up water. Heating up the water to create steam, which pushes the turbine. Spin the turbine to turn on the generator. Fundamental way to generate electricity is to have magnetic field rotating over a wire. Generator converts mechanical energy into electrical energy, produce ac current. Keep the temperature of the heat engine high, and the cold sink low. T h low temperature is around room temperature (300k), and the high temperature is 823k, by plugging the number, the efficiency would be 64%.
