Interview Questions and Answers

Preventing corrosion involves maintaining proper water chemistry, using corrosion inhibitors, and regularly inspecting the boiler for signs of corrosion.

Contributing to sustainability involves optimizing boiler efficiency, reducing emissions, and implementing energy-saving practices.

Career advancement opportunities include becoming a chief boilerman, plant supervisor, or boiler inspector.

Troubleshooting involves checking fuel supply, burner operation, water level, pressure settings, and control system parameters.

Energy efficiency measures include optimizing combustion, reducing heat loss, improving water treatment, and implementing waste heat recovery systems.

Responding to a boiler emergency involves shutting down the boiler, evacuating the area, and contacting emergency services.

Boiler operation is regulated by various codes and standards, such as the ASME Boiler and Pressure Vessel Code and local boiler safety regulations.

The economizer preheats feedwater using exhaust gases from the boiler, increasing efficiency and reducing fuel consumption.

Adjusting the air-fuel ratio involves using dampers or control valves to regulate the amount of air and fuel entering the burner, optimizing combustion efficiency.

Blowdown removes accumulated sediment and dissolved solids from the boiler, preventing scaling and corrosion that can reduce efficiency and damage the boiler.

The combustion control system regulates the fuel-air mixture to ensure efficient and safe combustion within the boiler.

To produce steam, boilers are used. A boiler uses the generation portion of a steam system to add energy to a feedwater supply to produce steam. Energy is released either from the burning of fossil fuels or from waste heat from the process

Boiler mountings such as - safety valve, steam stop valve, vent valve, pressure gauge, water level indicator, feed check valve and fusible plug are set of safety device installed for the safe operation of a boiler.

It is a shell-mounted non-return valve which is slightly below the usual water level of the boiler. The Feed Check valve controls the supply of the boiler's feed water pump. If the feed pump fails, it also prevents backflow from the boiler to the pump. P

Piston valves are one form of valve used to control the flow of steam within a steam engine or locomotive. They control the admission of steam into the cylinders and its subsequent exhausting, enabling a locomotive to move under its own power.

Eight.

Basic steps:
- Make sure that the boiler's vent valve is open and ensure that there is no pressure in the boiler.
- Check that the steam stop valve is closed.
- Check that all the fuel valves are open and let the fuel flow through the system unt

Ensure that any form of obstruction such as fabric does not restrict the boiler vents.  Often search for leakage from any suspicious location of steam, water, air and flue gases. Follow the boiler manual for your boiler to operate safely and efficiently.

These ensure optimal running of the boiler. They also help in running the boiler safely.

The primary boiler fuels are coal, oil, and gas.

Haycock and wagon top boilers.
- Cylindrical fire-tube boiler.
- Multi-tube boilers.
- Solid fuel firing.
- Firetube boiler.
- Superheater.
- Water tube boiler.
- Supercritical steam generator.

Ideal Steam: Fuel ratio for Oil & Gas, 14.5 - 15. And if it is a coil-type boiler, then 6 - 7. Ideal for Solid-fuel (wood, husk), 3.5 - 4.

NA

A boiler incorporates a firebox or furnace in order to burn the fuel and generate heat. The generated heat is transferred to water to make steam, the process of boiling. This produces saturated steam at a rate which can vary according to the pressure abo

The removal of water from a boiler is a boiler blowdown. Its aim is to regulate boiler water parameters to reduce scale, corrosion, carryover, and other unique issues within specified limits. To remove suspended solids present in the system, Blowdown is a

Heat Recovery Steam Generator's (HRSG's) are waste heat boilers. The steam turbine or a downstream process uses the steam. The term HRSG refers to the waste heat boiler in a Combined Cycle Power Plant. These recover the heat from the gas to generate super
