What should be purged from the boiler before starting?
......ANSWER......Trapped air or contaminants.
What personal protective equipment (PPE) is essential during boiler
start-up? ......ANSWER......Appropriate PPE such as safety goggles,
gloves, and hard hats.
What is a key safety measure to follow during the start-up process?
......ANSWER......Following lockout/tagout procedures to isolate energy
sources.
What should be done to safely shut down a steam boiler?
......ANSWER......Gradually reduce the firing rate and allow the boiler to
cool down.
What maintenance task should be performed during boiler shutdown?
......ANSWER......Inspecting and cleaning the boiler tubes, furnace, and
other components.
What is the purpose of regular inspections of steam boilers?
......ANSWER......To maintain efficiency and ensure safe operation.
What is the recommended maintenance schedule for safety devices?
......ANSWER......Monthly inspections of safety devices and controls.

What is the primary function of a steam boiler? ......ANSWER......To
transfer heat energy produced by burning fuel to water, transforming it
into steam.
How do water-tube boilers differ from fire-tube boilers?
......ANSWER......Water-tube boilers have water-filled tubes through
which hot gases flow, heating the water inside.
What is one method used for water heating in steam boilers?
......ANSWER......Electric boilers use electric resistance heating elements
to heat water directly.
What factors influence efficiency in water heating?
......ANSWER......Boiler design, water quality, and combustion
conditions.
What is the first step in the fuel combustion process?
......ANSWER......Fuel preparation, which may involve grinding,
pulverizing, or drying the fuel.
What is the role of combustion air control in steam boilers?
......ANSWER......To ensure complete fuel combustion, minimizing
pollutants and maximizing heat transfer.
