1.- Oil Circulation in the System
- ANSWER The process of oil circulation from the tank at the lowest floor of a
building to the burner on the floor above such floor through the pump.
2.- Oil Circulation in the System
Oil storage tank
- ANSWER Provides the supply of oil for combustion in the oil burner. It is inside
a dike. In case of a leak the diked area will contain the oil. In its normal
condition, #2 fuel-oil is thin and light and is easily pumped through the
circulation system
3.- Oil Circulation in the System
A Suction pump
- ANSWER Circulates the oil throughout the system. Dirt and sediment are
present in the fuel-oil coming from the oil storage tank. The oil filter removes
most of these contaminants from the oil before the oil reaches the burner's
strainer.
4.- Oil Circulation in the System
The Suction Line
- ANSWER Has to be 6 inches from the bottom of the tank for sediments not to
be absorbed. The vacuum gauge is a device that measures pressure below
,atmospheric pressure. Excessive vacuum readings indicate that there is an
obstruction in the suction line (such as dirty oil strainer). When this occurs the
flow of oil can be stopped by closing the shut-off valve. This permits the operator
to clean the filter/strainer or to perform other maintenance
5.- Oil Circulation in the System
Main Fuel Valve
- ANSWER Electrically operated and will open or close the line leading to the
atomizer only for oil burners. It will shut down the burner system if there is a
failure of ignition or combustion.
6.- Oil Circulation in the System
A Back Pressure Relief Valve
- ANSWER Oil circulates through the piping system back to the storage tank
through the oil return line. A back pressure relief valve is provided for safety if
the pressure becomes too great. Day tanks may be located throughout the
building above the lowest floor
7.- Oil Circulation in the System
A Separate Pump
- ANSWER Required for each day tank to supply each floor. In case of a leak in
the piping, leak collector is provided. Leak collector is stored by the storage tank.
It has a oil level gauge which shows the amount collected
8.- Oil Circulation in the System
Level Gauge
- ANSWER A gauge will show how much fuel oil is inside a main storage
tank/day tank.
9.- Oil Burner Operation
Combustion
,- ANSWER Is the chemical union of the oxygen in the air with combustible
elements in fuel-oil (hydrogen and carbon). The end result of this process is the
production of heat energy
10.- Oil Burner Operation
Oil Firing Equipment
- ANSWER Used to liberate heat energy from fuel-oil. Oil burners are the
principal components of the oil firing equipment and provide the means of
supporting the process of combustion.
11.- Oil Burner Operation
Two principal elements of fuel-oil
- ANSWER Carbon and hydrogen. During the combustion process, the carbon
content of fuel-oil (about 85%) unites with the oxygen in the air and forms
carbon dioxide and carbon monoxide. The hydrogen content of the oil (about
14%) unites with the oxygen and produces water. The objective is to have a
complete combustion process
12.- Oil Burner Operation
In order to support combustion
- ANSWER It must be changed to a gas or vapor and mixed with air
13.- Oil Burner Operation
The Oil burner
- ANSWER Primarily a device for processing the liquid fuel for combustion by
accelerating the change from liquid to a vapor that can be mixed with air and
burned.
14.- Oil Burner Operation
Atomizing Oil
, - ANSWER This process of breaking down or atomizing the oil is to ensure
prompt ignition and rapid combustion. Although there are various types of oil
burners, i.e. generator or boiler, they all vaporize or atomize the oil before it
enters the combustion chamber where it is mixed with air in predetermined
proportions.
15.- Oil Burner Operation
Oil burner uses an Oil Pump
- ANSWER Mixes air and oil within the nozzle itself. In oil burners, the oil and air
mixture is delivered to the nozzle at a pressure dependent upon the make of the
burner. The air that contacts the oil prior to its leaving the nozzle is referred to
as primary air.
16.- Oil Burner Operation
Secondary Air
- ANSWER The introduction of air from the blower or fan into the combustion
chamber after the oil has left the nozzle is referred to as "secondary air". Every
brand of oil burner is essentially different from that of other manufacturers
17.- Oil Burner Operation
The Diesel generators
- ANSWER Use injection nozzles without primary air, thus it is important that an
operator of a system understand the functions of his/her particular system
completely.
18.- Oil Burner Operation
Oil burners required approximately
- ANSWER 2000 cubic feet of air per gallon of oil consumed. The mixture of oil
and air is sprayed in vapor form into a firebox area (the combustion chamber)
where combustion takes place
19.- Oil Burner Operation
