Power Plant Manager Interview Questions and Answers

Long term planning goals for a power plant manager involve efficiency, sustainability, safety, and cost reduction.

• Increasing energy efficiency to reduce operational costs

• Implementing sustainable practices to reduce environmental impact

• Ensuring safety protocols are followed to prevent accidents and injuries

• Developing strategies to reduce overall operating costs

• Investing in technology upgrades for improved performance

I manage emergencies during failure by following established protocols, coordinating with team members, and prioritizing safety.

• Immediately assess the situation and determine the extent of the failure

• Activate emergency response procedures and notify relevant authorities

• Coordinate with team members to address the issue efficiently

• Prioritize safety of personnel and equipment

• Communicate effectively with all stakeholders throughout the process

Interlocks in a boiler turbine are safety mechanisms that prevent unsafe conditions and protect equipment.

• Interlocks ensure proper sequencing of operations in the boiler turbine

• They prevent unsafe conditions such as overpressure, low water level, or flame failure

• Examples of interlocks include low water level shutdown, high steam pressure trip, and flame failure detection

• Interlocks help protect equipment from damage and ensure safe operation of the power plant

Heat rate is the amount of fuel energy required to produce a unit of electricity. Light up and TG rolling are related to power plant startup.

• Heat rate is measured in BTU/kWh or kJ/kWh

• It is affected by factors such as boiler efficiency, turbine efficiency, and generator efficiency

• Light up refers to the process of starting up a boiler from a cold state

• TG rolling refers to the process of starting up a turbine generator

• Both light up and TG rolling are critical steps in power plan...read more

Boiler efficiency can be calculated by measuring the heat input and heat output of the boiler.

• Measure the fuel input and steam output of the boiler

• Calculate the heat input by multiplying the fuel flow rate with the calorific value of the fuel

• Calculate the heat output by multiplying the steam flow rate with the enthalpy of the steam

• Divide the heat output by the heat input and multiply by 100 to get the boiler efficiency

• Regular maintenance and cleaning of the boiler can improve...read more

Steam turbine bearing clearance is the gap between the bearing and the shaft.

• Bearing clearance is important for proper lubrication and to prevent damage to the bearing and shaft.

• Clearance can be adjusted by shimming or machining the bearing housing.

• Clearance should be checked regularly and adjusted as needed to maintain optimal performance.

• Excessive clearance can cause vibration and damage to the turbine.

• Insufficient clearance can cause overheating and premature wear of the b...read more
