Question

State the necessity of waste heat recovery in thermal power plant.​

Answer 1

Answer:

The use of a waste heat boiler in this case allows the recovery and utilisation of the heat of the flue gas to vaporise a fluid and produce steam that can be used for energy generation through turbines and generators. The pressure and the rate of steam production mainly depends on the temperature of the waste heat.

Answer 2

Answer:

Waste heat recovery is so important because by reducing the amount of fuel used to produce heat.

Explanation:

• Increased energy efficiency is a constant challenge for industry, energy prices are rising globally so there is a short term necessity to reduce fuel bills in order to remain competitive, which is why waste heat recovery is so important.
• Waste heat recovery is so important because by reducing the amount of fuel used to produce heat in a boiler installation, heating efficiency increases, resulting in lower fuel use. This serves both the requirement to increase efficiency and reduce carbon emissions.
