I applied via Walk-in and was interviewed in Dec 2020. There were 3 interview rounds.
Boiler efficiency is a measure of how effectively a boiler converts fuel into usable heat energy.
Boiler efficiency is expressed as a percentage.
It is calculated by dividing the energy output of the boiler by the energy input.
Factors affecting boiler efficiency include combustion efficiency, heat transfer efficiency, and excess air levels.
Improving boiler efficiency can lead to significant energy savings and reduced emi...

A single mechanical seal consists of one set of sealing surfaces, while a double mechanical seal consists of two sets of sealing surfaces.
Single mechanical seals are commonly used in applications with low to moderate pressure and temperature.
Double mechanical seals are used in applications with high pressure and temperature to provide an extra layer of protection.
Single mechanical seals are simpler and easier to instal...
The type of gearbox used in SSR reactors is typically a helical gearbox.
SSR reactors commonly use helical gearboxes for their efficient power transmission.
Helical gearboxes have high load-carrying capacity and smooth operation.
They are suitable for applications requiring high torque and low noise levels.
Examples of helical gearboxes used in SSR reactors include inline helical gearboxes and parallel shaft helical gearbo
