NTPC Interview Questions, Process, and Tips

Q1. Why we can't more efficiency in Boiler
Ans. 
Efficiency in boilers is limited due to various factors.
• Incomplete combustion of fuel leads to energy loss

• Heat loss through flue gases and radiation

• Inefficient heat transfer due to scaling or fouling

• Improper insulation leading to heat loss

• Inadequate maintenance and tuning

• Lack of advanced control systems

• Design limitations and constraints

• Fuel quality and composition

• Operating conditions and load variations

Q2. Why Turbine,s efficiency is less & so derive the efficiency equation
Ans. 
The efficiency of a turbine is less due to various factors such as friction, heat losses, and mechanical losses.
• Friction between the moving parts of the turbine reduces its efficiency.

• Heat losses occur due to the conversion of thermal energy into mechanical energy.

• Mechanical losses include losses in bearings, seals, and other components.

• Efficiency equation: Efficiency = (Useful output energy / Input energy) * 100%
