SKV Energy Services Commissioning Engineer Interview Questions, Process, and Tips

The question is unclear. 1 MW is a unit of power, not a unit of measurement.

• 1 MW is a unit of power, not a unit of measurement

• It is like asking how many pounds are in a mile

• The question needs to be rephrased or clarified

The outlet temperature of coal mill depends on various factors such as coal type, mill capacity, and air flow rate.

• Outlet temperature is typically measured in degrees Celsius or Fahrenheit.

• The temperature can range from 60 to 120 degrees Celsius depending on the above factors.

• The temperature needs to be carefully controlled to prevent overheating and potential fires.

• Regular monitoring and maintenance of the coal mill i...read more

VFDs are used in power plants to control the speed of motors and pumps, resulting in energy savings and improved process control.

• VFDs are used in boiler feed pumps to control the flow of water to the boiler, resulting in improved efficiency and reduced wear and tear on the equipment.

• VFDs are used in cooling tower fans to adjust the speed of the fan based on the cooling demand, resulting in energy savings.

• VFDs are used ...read more

The coal mill can trip on various reasons such as coal hang-up, mill overload, flame detector failure, etc.

• Coal hang-up: when coal sticks to mill internals due to high moisture content or poor coal quality

• Mill overload: when the mill motor is overloaded due to high coal flow or low grindability

• Flame detector failure: when the flame detector fails to detect the flame in the furnace

• Other reasons: such as feeder blockage,

Flue gas outlet temperature is the temperature of the gas leaving the combustion chamber.

• Flue gas outlet temperature is an important parameter to monitor the efficiency of a combustion process.

• It is usually measured using a thermocouple or infrared thermometer.

• The temperature should be within the design limits to avoid any damage to the equipment.

• For example, in a gas turbine, the flue gas outlet temperature should not...read more
