Flue gas flow in a steam power plant layout refers to the path that flue gas takes as it moves through various components of the power plant. The correct order for flue gas flow in the steam power plant layout is option 'A', which is superheater, economizer, air preheater.
1. Superheater:
The superheater is the first component in the flue gas flow path. It is located after the steam turbine and is responsible for heating the saturated steam to a higher temperature. The superheater is typically composed of a series of tubes where the flue gas passes over and transfers heat to the steam, increasing its temperature.
2. Economizer:
After passing through the superheater, the flue gas enters the economizer. The economizer is a heat exchanger that utilizes the waste heat from the flue gas to preheat the feedwater before it enters the boiler. This increases the overall efficiency of the power plant as it reduces the amount of fuel required to heat the water in the boiler.
3. Air Preheater:
Once the flue gas exits the economizer, it enters the air preheater. The air preheater is another heat exchanger that uses the waste heat from the flue gas to preheat the combustion air before it enters the boiler. This improves the combustion process and again increases the overall efficiency of the power plant by reducing the fuel consumption.
By following the sequence of superheater, economizer, and air preheater, the flue gas flow is optimized in terms of heat transfer and energy efficiency. The waste heat from the flue gas is effectively utilized to increase the temperature of the steam, preheat the feedwater, and preheat the combustion air, leading to a more efficient operation of the steam power plant.
In summary, the correct order for flue gas flow in a steam power plant layout is superheater, economizer, air preheater. This ensures that the waste heat from the flue gas is effectively utilized to improve the overall efficiency of the power plant.
