2. Continous Attendance
3. Non-Continous Attendance

• Boilers from 9-250 HP require periodic attendance
• Boilers from 251-500 HP require Non-Continous attendance
• Boilers over 501 HP require continous attendance

1. Manufacturers tag
2. ((Steam Output LBS/HR)/34.5)
3. ((BTU/HR input)/41,840)
4. ((BTU/HR output)/33,475)

How often Must a Boiler be inspected?

• All boiler operating over 15 PSI unless otherwise exempted shall be inspected internally and externally once a year

How do you Blow down a Boiler?

• Find true water level (1/2 gauge glass or better)
• Open cooling water to blowdown tank
• Open quick opening Valve (inside Valve)
• Open Slow opening Valve (outside Valve) fully wide and Close it
• Close Quick opening valve
• Check level and secure cooling water to blow down tank

When is more than one steam stop valve required?

• When there is 2 or more boilers on a common header and if the boiler has Man holes and hand holes

• The water column is blow down opening the drain valve fully wide then closing it...Disable low water cut off to avoid tripping boiler
• The gauge glass needs to be blown down by operating the top and bottom valves independently to ensure that neither connection is plugged

When is more than 1 bottom blow down valve required?

• 2 or more Blow down valves are required when the boiler is operating at 100 psi and above

• The main steam stop valve is used to isolate the boiler from other boilers on a common header usaully for cleaning, repair, and/or Inspection

GATE VALVE

• A Gate Valve is an isolation valve used either fully open or fully closed, not designed to use for throttling applications

GLOBE VALVE

• A Globe Valve is an Isolation valve that is designed for throttling applications

• If there is only one safety valve on a boiler, What is it set at?

• If there is only one safety valve on the Boiler than it will set at or below Maximum Working Pressure

NONE

Why is the superheater safety valve set to open first?

• The Super heater safety valve blow first to asure flow thru Superheater

What is an economizer?

• An Economizer is heat recovery equipment Designed to add heat to the incoming feed water by reducing the exiting flu gas temperature

What is a PRE-Heater?

• An Air Preheater is heat recovery equipment designed to add heat to the incoming combustion air by reducung the exiting flu gas temperature

• In an Open feed water heater, Steam and water come in deirect contact with each other
• In a closed feed water heater steam and water do not come in direct contact with each other

What is sensible heat?

• Sensible heat is heat added to a substance that cause a change in temperature that can be measured with a thermometer

What is Latent heat?

• Latent Heat is heat that is added to a substance that causes a change of state with out change in temerature

What is the definition of a BTU?

BTU

(British Thermal Unit)

• The amount of heat needed to raise the temp of one lbs of water one degree fahrenheit

• Saturated steam is steam with same temperature as the water from which it was generated
• Super heated steam is steam at a temperature higher that temperature corresponding to its pressure
• Saturated steam is dry steam with no moisture in it

What is the definition of boiler heating surface?

• The surface for the absorption and transfer of heat from one medium to another.

What happens to the saturation point once the boiler pressure starts to rise? 

• As boiler pressure increases the saturation point of the water decreases

Three Things that a Deaerator does?

• Removes oxygen and Non-combustible gases
• Heats the Feed water
• Acts as storage capacity for the system

Instrument readings on a D.A?

What proceedure is used to turn over watch?

• Walk through plant and check all safety valves, and gauges, as well as ask any questions you might have for the off going shift before turning over
• i.e........Check water levels in Boilers and all other AUX equipment

What the difference between an HRT and a Scotch-Marine Boiler?

• An HRT Boiler is externally fired, the Scotch-Marine is internally fired

What does a steam Trap do?

• Steam traps are automatic devices that increase the overall plant efficiency by removing air and water from steam lines with out the loss of steam

What is an inverted bucket trap do?

• As steam flows in to the valve the bucket rises and trap steam and non condensible gases in side, as condensate fills the trap the bucket loses buouyancy and open valve and releses condesate

Name 2 types of Soot Blowers?

• Stationary and Retractable

3 Precautions that you would take before entering a Boiler?

1. Lockout Tag out
2. Open free blow drain valve
3. Find an person to stand watch outside the boiler

How often should Safety valve be tested?

• Before Each start up of Boiler

How often should blow down valve be operated?

• You should blow down the boiler at a reduced rate when ever possible

• What is Critical Pressure steam
