Boiler and Turbine Desk Engineer Interview Questions and Answers

Plant efficiency is a measure of how well a plant converts input energy into useful output energy.

• Plant efficiency is calculated by dividing the useful output energy by the input energy and multiplying by 100 to get a percentage.

• Efficiency can be affected by factors such as equipment condition, fuel quality, and operating practices.

• For example, a plant with an efficiency of 40% would convert 40% of the input energy into useful output energy.

Losses in a plant refer to energy losses that occur during the operation of equipment, leading to decreased efficiency.

• Losses can be categorized as mechanical losses, electrical losses, thermal losses, and hydraulic losses.

• Mechanical losses include friction in bearings, gears, and seals.

• Electrical losses occur due to resistance in conductors and transformers.

• Thermal losses result from heat dissipation in equipment like boilers and turbines.

• Hydraulic losses are caused by press...read more

Heat rate is a measure of how efficiently a power plant uses fuel to generate electricity.

• Heat rate is the amount of energy required to produce a unit of electricity, typically measured in British thermal units (BTUs) per kilowatt-hour (kWh).

• A lower heat rate indicates a more efficient power plant, as it means less fuel is needed to generate the same amount of electricity.

• Factors affecting heat rate include the type of fuel used, the age and condition of the equipment, and th...read more

Active end flow of steam refers to the flow of steam at the outlet end of a turbine or boiler.

• Active end flow of steam is the steam flow at the outlet end of a turbine or boiler.

• It is important to monitor and control the active end flow to ensure efficient operation.

• High active end flow can indicate issues such as turbine overload or boiler inefficiency.

• Examples of monitoring active end flow include using flow meters and pressure sensors.
