Turbine DCS Engineer Interview Questions and Answers

The heat rate of a turbine is a measure of its efficiency in converting fuel into electricity. It is calculated by dividing the total energy input by the electricity output.

• Heat rate is calculated by dividing the total energy input (in BTUs) by the electricity output (in kWh).

• Normal parameters for DCS boiler/turbine include temperature, pressure, flow rates, and efficiency.

• Condenser capacity is the amount of heat that can be removed from the steam in a given time period.

• Steam...read more

Turbine rolling process is the process of rotating the turbine rotor to ensure proper alignment and balance.

• Turbine rolling process is done to ensure proper alignment and balance of the rotor.

• It involves rotating the rotor at a slow speed to check for any vibrations or misalignments.

• The process is usually done during the commissioning of a new turbine or after maintenance work.

• Turbine rolling process is important for the safe and efficient operation of the turbine.

• It helps to...read more

Turbine heat rate and efficiency are important factors in determining the performance of a turbine.

• Turbine heat rate is the amount of fuel energy input required to produce a unit of electricity output.

• Turbine efficiency is the ratio of the actual work output of the turbine to the theoretical maximum work output.

• Improving turbine efficiency and reducing heat rate can result in significant cost savings and environmental benefits.

• Factors that affect turbine heat rate and efficie...read more

The best operation of a turbine involves proper startup procedures, efficient operation, and safe shutdown protocols.

• Ensure all safety checks are completed before starting the turbine

• Monitor and adjust turbine parameters to maintain optimal performance

• Follow manufacturer's guidelines for shutdown procedures to prevent damage

• Regular maintenance and inspections to ensure smooth operation

• Implement proper cooling and lubrication systems to prevent overheating and wear

Handling block out condition involves identifying the cause, implementing safety measures, and restoring normal operation.

• Identify the cause of the block out condition

• Implement safety measures to prevent further damage or accidents

• Restore normal operation by troubleshooting and fixing the issue

• Document the incident and take preventive measures for future occurrences

Vaccum drop in a turbine can be caused by air leakage, steam leakage, or malfunctioning equipment.

• Air leakage in the system

• Steam leakage in the system

• Malfunctioning equipment such as valves or seals

• Low condenser vacuum due to cooling water temperature increase

• High turbine exhaust pressure

Downtime costs include lost production, repair expenses, and potential damage to reputation.

• Calculate lost production revenue during downtime

• Consider repair expenses for fixing the issue causing downtime

• Factor in potential damage to reputation and customer trust

• Implement preventive maintenance to reduce downtime costs

• Invest in spare parts inventory to minimize downtime
