Electrical Engineering XYZ MCQs
The steam power plant efficiency can be improved by:
- Using high temperature and high pressure steam
- Using large quantity of water
- Burning large amount of coal
- Decreasing the load on the plant
Correct answer: 1. Using high temperature and high pressure steam
Explanation: Using high temperature and high pressure steam is the most efficient method to improve the efficiency of a steam power plant. High temperature and high pressure steam allow for more work to be extracted from the steam in the turbine, increasing the overall efficiency of the plant. The higher the temperature and pressure of the steam, the more energy can be extracted from it as it expands through the turbine.
