The journey combustion gasses take through a boiler is called what

The  (Flue or Combustion) Gas path

100

A low pressure steam boiler is one which operates

at or below 103 kPa

100

The Flat ends of a firetube boiler Where the tubes are attached is often referred to as the

Tubesheet 

100

A packaged watertube boiler with two " mud Drums " is called what 

An "A" type Boiler 

200

These "End Pieces" are welded onto the cylindrical part of the steam drum 

What is The Head 

200

In a Watertube boiler Which Side will see greater pressure  the furnace or the Water side

The waterside of course.

200

The first boiler to have firetubes became known as the

HRT boiler

200

With regard to a steam boiler, the lettering "HRT" means

horizontal return tubular

200

In a Water tube boiler design, What side of the watertube is the combustion gas in 

External side or outside

300

The most common type of welding used in Modern Steam drum manufacturing is 

Submerged arc Welding 

300

In a watertube boiler the furnace is shrouded by what 

Water tubes 

300

A steam boiler should be compact in design in order to

reduce building costs

300

A component used to increase the volume of the steam space in a locomotive boiler was the

Steam Dome 

300

The upper drum on a watertube boiler is called the 

Steam drum

400

Bent tube boiler designs Allows for the tubes to be attached Radially on what 

the outside of the shell or drum 

400

in a firetube boiler The furnace and combustion gas tubes, bust be designed to withstand to what type of pressure 

external pressure 

400

The lowest permissible water level of a power boiler is

50 mm below the lowest visible water line

400

The firetube boiler in the Lab here at NBCC Has  how many passes 

Four Passes 

400

The Lower drum on a Water tube boiler is also called the 

Mud drum          1 extra point if you can tell me Why?

500

in a longitudinal strait tube boiler The downcomer Feeds What ?

Cool Water to the front header

500

In a firetube boiler Adding more Flue gas paths may result in this negative effect 

Corrosion at the smoke box and flue gas stack due to overcooling . 

500

Safety, efficient operation, and economical fuel consumption

are

main considerations when designing boilers

500

A device used to prevent the carry-over of moisture with the steam of an HRT boiler is the

dry pipe

500

The use of bent tube boiler designs allows the furnace wall to be lined with tubes, thereby exposing more of the heating surface to

Radiant Heat
