A thermal power plant is a facility that converts heat energy into electrical power.

• Thermal power plants use fossil fuels, nuclear energy, or renewable sources to generate heat.

• The heat is used to produce steam, which drives a turbine connected to a generator.

• The generator converts mechanical energy into electrical energy.

• Common types of thermal power plants include coal-fired, gas-fired, and nuclear power plants.

• Examp...read more

Thermal power plant efficiency is the ratio of energy output to energy input.

• Efficiency can be improved by using high-quality fuel and improving the combustion process.

• Regular maintenance of equipment and proper insulation can also improve efficiency.

• Cogeneration, where waste heat is used for other purposes, can increase efficiency.

• Efficiency can be calculated using the formula: Efficiency = Energy output / Energy inpu...read more

De-ashing process from ESP to silo involves several steps.

• The ash is collected in hoppers located at the bottom of the ESP.

• The ash is then transported to the silo using a pneumatic conveying system.

• The ash is stored in the silo until it can be disposed of properly.

• Regular maintenance of the ESP and pneumatic conveying system is necessary to ensure efficient de-ashing.

• Proper safety measures must be taken during the de-a

The capacity of ESP hoppers varies depending on the size and model of the equipment.

• ESP hoppers can range from a few hundred cubic feet to several thousand cubic feet in capacity.

• The capacity can also depend on the type of material being collected in the hopper.

• It is important to regularly monitor and maintain the hopper to prevent overfilling and potential equipment damage.
