Efficiency of fired boilers can be calculated by dividing the energy output by the energy input.

• Efficiency = (Energy output / Energy input) * 100%

• Energy output can be measured in terms of steam production or heat transfer to water

• Energy input is the fuel energy input to the boiler

• Efficiency can be improved by optimizing combustion, insulation, and heat recovery systems

The erection sequence of a bi drum boiler involves several key steps to ensure proper installation and functionality.

• Start by preparing the foundation for the boiler to ensure stability and support.

• Next, assemble the lower drum and connect it to the foundation securely.

• Then, install the upper drum and connect it to the lower drum using appropriate fittings.

• After that, install the boiler tubes and headers to facilitate the flow of water and steam.

• Finally, conduct thorough test...read more

Safety interlock of fired boilers is a crucial system that ensures safe operation by preventing unsafe conditions.

• Safety interlock system is designed to shut down the boiler if unsafe conditions are detected, such as low water level or high pressure.

• Interlocks may include sensors, alarms, and automatic shutdown mechanisms.

• Regular maintenance and testing of safety interlock systems are essential to ensure they function properly.

• Examples of safety interlock devices include pres...read more

Boiler and turbine light up procedure

• Check fuel and water levels

• Purge air from the system

• Start the boiler and bring it to operating pressure

• Open the turbine inlet valve and gradually increase load

• Monitor and adjust parameters as necessary

Weld visual inspection is required to ensure the quality and integrity of the welds.

• Visual inspection helps to detect any surface defects or discontinuities in the welds.

• It ensures that the welds meet the specified standards and requirements.

• Visual inspection is a non-destructive testing method that is cost-effective and easy to perform.

• It helps in identifying issues early on, preventing potential failures or accidents.

• Examples: checking for cracks, porosity, incomplete penet...read more

I have attended various sites for training and workshops related to after sales service.

• Attended manufacturer's training site for product knowledge

• Visited customer sites to understand their service needs

• Participated in industry conferences and seminars

Air compressors work by compressing air to increase its pressure, which can then be used for various applications.

• Air is drawn into the compressor through an intake valve

• The air is then compressed using a piston or rotating impeller

• Compressed air is stored in a tank for later use

• The compressed air is released through a valve when needed for powering tools or equipment

• Regular maintenance, such as changing filters and oil, is necessary to ensure proper functioning

DAF stands for Dissolved Air Flotation, a water treatment process used to remove suspended solids, oils, and other contaminants.

• DAF involves the introduction of fine air bubbles into a water stream to float the particles to the surface for removal.

• It is commonly used in industrial wastewater treatment plants.

• DAF is effective in removing contaminants such as oils, grease, and suspended solids.

• The floated particles are then skimmed off the surface for disposal.

• DAF is a cost-eff...read more

The gearbox is a mechanical device that transmits power from the engine to the wheels of a vehicle, allowing for different speeds and torque ratios.

• The gearbox contains gears of different sizes that mesh together to change the speed and torque of the vehicle.

• It is typically located between the engine and the driveshaft.

• Gearboxes can be manual or automatic, with manual gearboxes requiring the driver to shift gears manually.

• Some vehicles also have CVT (continuously variable tra...read more

There are various types of belts used in engineering, such as V-belts, timing belts, flat belts, and conveyor belts.

• V-belts are commonly used for power transmission in machinery.

• Timing belts are used to synchronize the rotation of the crankshaft and camshaft in an engine.

• Flat belts are used for conveying loads over long distances.

• Conveyor belts are used for moving materials in industrial settings.
