Fasteners Allied Products Interview Questions and Answers

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: Turbine start permissive allows the turbine to start only...read more

Equipment used in steam turbine include turbine blades, nozzles, casing, rotor, bearings, and governor.

• Turbine blades: convert steam energy into mechanical energy

• Nozzles: control the flow of steam into the turbine

• Casing: contains and directs the steam flow through the turbine

• Rotor: connected to the turbine blades and rotates to generate power

• Bearings: support the rotor and reduce friction

• Governor: regulates the speed of the turbine

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 based on the rate of change of the error.

• The combined use of ...read more
