used to establish non relief capacity

b)

used to see if your boiler system is gaining intelligence

c)

used to establish relief capacity of boiler safety valves

provides power and motion needed to manipulate moving parts of a valve

b)

steam trap in which a temperature sensitive bimetallic element controls a valve

c)

damper used to control fluid flow through a final element

7.

air atomizing burner...

a burner used for cooking every atom of carbon fuel

b)

A heat exchanger that is used to heat combustion air for a furnace and is located in the breeching between the boiler and the stack

c)

air's worst nightmare

d)

A fuel oil burner that sends compressed air and pressurized fuel oil through a nozzle into the furnace where the vaporized fuel mixes with air and is ignited

8.

air heater

a)

automatically controlling the amount of boiler blowdown in order to maintain the level of total dissolved solids

b)

the process of opening valves t blow water or steam through a fitting or from a boiler in order to remove any sludge, sediment, or other undesirable particles

Alkaline water is any water with a pH (a)   than 7

10.

analyzer sampling system...

a)

a system of valves and modulars operated to breakdown substrate and process it in order to sense combustion levels

b)

analyzes the steam and vapors emit and determines whether or not they are of a acidic nature

c)

on/off control used to handle combustion control in order to start or stop a burner with no modulation to the flame

d)

A system of piping, valves, and other equipment used to extract a sample from a process, condition it if necessary, and convey it to an analyzer
