10+ Institute of Language Management Interview Questions and Answers

The percentage setting of a line safety valve depends on the specific system and its requirements.

• The percentage setting is determined by the pressure drop across the valve and the required flow rate.

• Typically, line safety valves are set between 10-20% above the system's operating pressure.

• However, this can vary depending on the specific system and its requirements.

• It is important to ensure that the valve is set correctly to prevent overpressure and potential safety hazards.

The type of oil used in turbines is typically turbine oil.

• Turbine oil is specifically designed to meet the lubrication requirements of turbines.

• It has excellent thermal stability and oxidation resistance.

• Turbine oil helps reduce friction and wear in the turbine's moving parts.

• It also provides cooling and helps remove contaminants from the system.

• Different types of turbine oils are available, such as mineral-based, synthetic, and bio-based oils.

The back pressure turbine is experiencing a flow imbalance between the inlet and outlet, resulting in a lower outlet flow than the inlet flow.

• Possible causes could include a restriction in the turbine outlet, leakage in the system, or incorrect measurement of flow rates.

• Check for any blockages or obstructions in the turbine outlet that may be causing the flow imbalance.

• Verify the accuracy of the flow measurement devices to ensure correct readings are being obtained.

The question is asking about the tonnage flow rate of the attemper flow.

• The tonnage flow rate refers to the amount of material or substance flowing through a system per unit of time.

• The attemper flow is a term used in control room engineering to describe the flow of a cooling medium, such as water, to regulate temperature.

• To answer the question, specific data on the attemper flow rate in tons would be required.

Emergencies in a thermal power plant can include fires, equipment failures, and electrical faults.

• Fires can occur due to fuel leaks or electrical malfunctions.

• Equipment failures can lead to shutdowns or accidents.

• Electrical faults can cause power outages or damage to equipment.

• Other emergencies may include steam leaks, chemical spills, or worker injuries.

There are various types of work permits depending on the country and purpose of employment.

• Temporary work permits

• Permanent work permits

• Seasonal work permits

• Student work permits

• Intra-company transfer work permits

• Skilled worker permits

• Business visit permits

pH value is critical in feed pump and boiler to maintain water quality and prevent corrosion.

• pH value in feed pump should be between 7.5 to 9.5 to prevent corrosion and scaling

• pH value in boiler should be between 10.5 to 12.0 to prevent acidic corrosion

• pH value can be controlled by adding chemicals like sodium hydroxide or sulfuric acid

• Regular monitoring and adjustment of pH value is necessary to ensure efficient operation and prevent damage

The boiler light up procedure is the process of starting and igniting a boiler to generate steam.

• Ensure all safety measures are in place before starting the procedure.

• Open the boiler's fuel and air supply valves.

• Purge the boiler of any remaining gases.

• Ignite the pilot burner or spark igniter.

• Monitor the flame and adjust fuel and air flow as needed.

• Gradually increase the boiler's load and steam pressure.

• Perform necessary checks and tests to ensure proper functioning.

• Continue m...read more

• The choice of tube material depends on factors such as the intended application, temperature, press...read more

Interlocking of boiler is a safety mechanism that prevents unsafe conditions in the boiler.

• Interlocking ensures that all safety devices are in place and functioning properly before the boiler can start.

• It also prevents the boiler from starting if any of the safety devices fail or malfunction.

• Interlocking can be achieved through electrical or mechanical means.

• Examples of interlocking devices include pressure switches, temperature sensors, and flow switches.

• Interlocking is an i...read more

Turbine rolling procedure is a process of slowly rotating the turbine to check for any abnormalities before starting it.

• The turbine is rotated at a slow speed to check for any vibrations or unusual noises.

• The rolling procedure is done to ensure the turbine is in good condition before starting it.

• The procedure is usually done by the control room engineer or the turbine operator.

• If any abnormalities are detected during the rolling procedure, the turbine is shut down and mainten...read more
