Q4. What is PID and How does it work ?
Ans. 
PID stands for Proportional-Integral-Derivative, a control loop feedback mechanism used in engineering.
• PID is a control algorithm that calculates an error value as the difference between a desired setpoint and a measured process variable.

• Proportional (P) control responds to the current error value.

• Integral (I) control accumulates past errors to correct the present error.

• Derivative (D) control predicts future errors bas...read more

Q6. Tell the interlock and permissive of boiler and turbine?
Ans. 
Interlocks and permissives are safety mechanisms in place to prevent unsafe operation of boiler and turbine systems.
• Interlocks prevent certain actions from taking place unless specific conditions are met

• Permissives allow certain actions to take place only if specific conditions are met

• Example of interlock: Boiler feed pump interlock prevents the boiler from starting unless the feed pump is running

• Example of permissive:...read more
