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
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%
Factors affecting power plant efficiency include type of fuel, technology used, maintenance, and operating conditions.
Type of fuel used (coal, natural gas, nuclear, etc.)
Technology used in the power plant (combined cycle, cogeneration, etc.)
Maintenance practices (regular maintenance vs. neglect)
Operating conditions (temperature, pressure, load demand)
Efficiency of heat transfer processes
Size and age of the power plant

NTPC interview questions for popular designations
Cube strength of 7 days is the compressive strength of concrete cubes after 7 days of curing.
Cube strength is an important measure of the quality and durability of concrete.
It is determined by conducting compression tests on concrete cubes after a specified curing period.
The cube strength at 7 days is an early indication of the ultimate strength of the concrete.
It is typically expressed in megapascals (MPa) or pounds p

Barring gear is a mechanism used in turbines to rotate the rotor during maintenance or inspection.
Barring gear is typically used in steam turbines and gas turbines.
It consists of a gear system that connects to the rotor shaft.
The gear system allows for controlled rotation of the rotor.
Barring gear is used when the turbine is shut down and the rotor needs to be turned manually.
It is commonly used for maintenance tasks s...
Vacuum is needed in turbines to create a pressure difference that drives the turbine blades and generates power.
Vacuum creates a pressure difference that drives the turbine blades.
The pressure difference causes the blades to rotate, converting kinetic energy into mechanical energy.
The mechanical energy is then used to generate power.
Vacuum is necessary for efficient turbine operation and power generation.
