Sunil Ispat And Power Turbine DCS Operator Interview Questions and Answers

Vibration in turbines can occur due to unbalance, misalignment, resonance, or mechanical looseness.

• Unbalance in rotating parts

• Misalignment of shafts or bearings

• Resonance with natural frequencies

• Mechanical looseness in components

Types of bearings used in turbines include journal bearings, thrust bearings, and tilting pad bearings.

• Journal bearings are commonly used in turbines to support rotating shafts.

• Thrust bearings are used to handle axial loads in turbines.

• Tilting pad bearings are designed to provide stability and reduce vibration in turbines.

Parameters such as flow rate, steam pressure, and feedwater temperature are maintained to ensure proper operation of the turbine DCS system.

• Flow rate of steam must be controlled to maintain desired turbine speed and power output.

• Steam pressure needs to be regulated to prevent damage to turbine components.

• Feedwater temperature must be monitored to ensure efficient heat transfer in the boiler.

• Maintaining proper temperatu...read more
