Abellon Clean Energy Boiler DCS Engineer Interview Questions, Process, and Tips

Efficiency is the ability to do something in a way that achieves maximum productivity with minimum wasted effort or expense.

• Efficiency is a measure of how well a system or process performs.

• It is often expressed as a percentage of the total input that is converted into useful output.

• For example, a car's fuel efficiency is measured in miles per gallon (MPG).

• Efficiency can be improved by optimizing processes, reducing was...read more

Latent heat is the heat energy absorbed or released during a phase change without a change in temperature.

• Latent heat is the energy required to change the state of a substance without changing its temperature.

• It is the heat energy absorbed or released during processes like melting, vaporization, and condensation.

• During phase changes, the energy is used to break or form intermolecular bonds.

• Examples include the heat abs...read more

Sensible heat refers to the heat that causes a change in temperature without a change in phase.

• Sensible heat is the heat energy that can be sensed or measured by a thermometer.

• It is the heat that causes a substance to increase or decrease in temperature.

• Sensible heat does not result in a change of state or phase.

• For example, when ice is heated and melts into water, the heat absorbed during this process is sensible heat...read more

Types of losses in a boiler system

• Heat loss through walls and pipes

• Incomplete combustion of fuel

• Blowdown loss

• Radiation loss

• Stack loss

• Excess air loss
