Q

Model CB-LE
What Provides air for atomization of the fuel oil

25
Model CB-LE What cleans the air supply prior to entering air pump
Air Filter
26
Model CB-LE What prevents lubricating oil and compressed air from surging back through the pump and air filter when the pump stops.
Check Valve
27
Model CB-LE what Holds a supply of oil for lubricating the air pump.
Air-Oil Receiver Tank
28
Model CB-LE What Indicates the level of lubricating oil in the air-oil receiver tank.
Lube Oil Level Sight Glass
29
Model CB-LE What Cools the lubricating oil before it enters the air pump. A fan driven by the air pump motor circulates cooling air over the coil.
Lube Oil Cooling Coil
30
Model CB-LE What is Used when adding oil to the air-oil receiver tank.
Lube Oil Fill Pipe and Strainer
31
Which air pump system uses a sliding vane air compressor driven by a belt off the combustion air blower motor.
Model CB-OS
32
Model CB-OS Which switch is optional and Switch contacts open when the fuel oil pressure drops below selected pressure. Switch will interrupt the limit circuit upon loss of sufficient fuel oil pressure for correct combustion.
Low Oil Pressure Switch
33
Model CB-OS What Transfers fuel oil from the storage tank and delivers it under pressure to the burner system
Fuel Oil Pump
34
Where can the fuel oil pump be mounted
It can be mounted on a skid or to the frame of the appliance.
35
For smaller burners where is the gear pump mounted
Single stage gear pump is often mounted on the burner and driven by the blower motor
36
Where should filters and strainers be installed
Filters and strainers shall be installed upstream from the safety shutoff valve
37
For larger oil-fired burners what may be needed for safe lighting of the burner
a natural gas pilot
38
What controls flow of fuel to the pilot nozzle
A solenoid valve
39
When does the pilot shut off
Once the main burner is on and proved
40
What is provided to heat heavy oil to the point where it can be effectively atomized and burned
Oil heater
41
Most heavy oil heaters use what to heat up the oil
An electric heater
42
What do you use to change from one fuel to another
The selector switch
43
systems greater than 20 gph need what
A low oil interlock switch
44
What shall be provided for all preheated oil systems to cause a safety shutdown and lockout when he oil temperature exceeds pre-set limits.
A high oil temperature supervisory interlock
45
One of the functions of a nozzle is to atomize the fuel, why
To break it up into tiny droplets which can be vaporized in a much shorter period of time when exposed to high temperatures.
46
Can there be more than one orifice drilled into a nozzle for a higher capacity industrial oil-fired burner.
Yes
47
How does The manufacturer achieves different spray patterns and flame shapes
By altering pressure, how the axial force is applied to the oil (fancy way to describe how the oil is swirled, and the angle of discharge.
48
What are the two main methods of oil atomization for oil-fired burners
Pressure atomization Air atomization
49
Pressure atomization requires what
More powerful pump and motor assembly to create the amount of pressure at the oil tip
50
Air atomization requires what
An air compressor to be able to create the atomizing air needed to shear the oil in the tip
51
Does pressure or air atomization require more parts
Air
52
Oil pressure regulator is set at what pressure normally
100-300 (psi)
53
What is The turndown ratio for a pressure atomizing burner
3:1 to 4:1
54
Atomizing air pressures can range from what
5-75 psi
55
What is The turndown ratio for an air atomized burner
6:1 to 8:1
56
Which atomizing systems are simpler and less expensive than the air-atomizing type and are usually used for locomotive and small power plants
Steam atomizing
57
Steam pressure varying for atomizing burner
75 to 150 psi.
58
The oil pressure for steam pressure burner
10-15 psi
59
A steam atomizing burner turndown ratio is
8:1 to 10:1
