GlaxoSmithKline Pharmaceuticals Interview Questions, Process, and Tips

A boiler is a closed vessel in which water or other fluid is heated to generate steam or hot water.

• A boiler is used to generate steam or hot water for various applications.

• It works by heating water or other fluid inside a closed vessel.

• The heated fluid then circulates through pipes or tubes to transfer heat to the surrounding environment.

• Boilers are commonly used in power plants, industrial processes, and heating syste...read more

The calorific value of F.O oil is the amount of heat energy released when it is burned.

• F.O oil stands for Furnace Oil.

• The calorific value of F.O oil varies depending on its grade and composition.

• It is typically measured in units of BTU (British Thermal Units) per gallon or per liter.

• The higher the calorific value, the more heat energy is released when the oil is burned.

• This heat energy is used to generate steam in boil

Briquette calorific value is the amount of heat produced by burning one unit of briquette.

• Briquette calorific value varies depending on the type of briquette.

• It is usually measured in units of energy per unit of briquette, such as joules per gram or calories per gram.

• Higher calorific value means more heat is produced per unit of briquette.

• Briquettes made from different materials have different calorific values. For exa...read more

There are various types of boilers such as fire tube, water tube, electric, and biomass boilers.

• Fire tube boilers have hot gases flowing inside the tubes and water surrounds them.

• Water tube boilers have water flowing inside the tubes and hot gases surround them.

• Electric boilers use electricity to heat water and produce steam.

• Biomass boilers use organic materials like wood chips or pellets to generate heat.

Boiler trips can occur due to various running conditions such as low water level, high pressure, flame failure, etc.

• Low water level can cause the boiler to trip as it can lead to overheating and damage to the boiler.

• High pressure can also cause the boiler to trip as it can lead to safety concerns.

• Flame failure can cause the boiler to trip as it indicates a problem with the fuel supply or ignition system.

• Other running c...read more

Boiler daily activity involves monitoring, maintaining and repairing boilers.

• Check and record boiler pressure, temperature and water levels

• Inspect and clean boiler components such as burners, tubes and valves

• Perform routine maintenance tasks such as lubrication and filter replacement

• Troubleshoot and repair boiler malfunctions

• Ensure compliance with safety regulations and procedures

Annual passing process of boiler involves inspection, testing and certification of the boiler.

• The boiler is inspected for any damages or defects.

• The safety valves are tested to ensure they are functioning properly.

• The boiler is cleaned and any deposits or scale buildup is removed.

• The efficiency of the boiler is tested.

• The boiler is certified by a licensed inspector.

• The process is repeated annually to ensure the boiler

OPH stands for Operating Hours Per Year. It is a measure of the total number of hours a boiler operates in a year.

• OPH is an important metric used to determine the efficiency of a boiler.

• It is calculated by multiplying the number of hours the boiler operates in a day by the number of days it operates in a year.

• For example, if a boiler operates for 8 hours a day and 300 days a year, its OPH would be 2,400.

• OPH is used to ...read more

Economizer is a heat exchanger that recovers waste heat from flue gases to preheat the feedwater.

• Economizer is installed in the boiler exhaust gas flue to recover heat energy from the flue gas.

• It preheats the feedwater before it enters the boiler.

• Economizer increases the boiler efficiency and reduces fuel consumption.

• It can be of two types: non-condensing and condensing economizer.

• Non-condensing economizer recovers sen...read more
