OVERVIEW OF LOW PSI OIL BURNER OPERATION AND CONTROLS Oil Circulation in The System
The following material provides an overview description of the process of oil circulation in the burner system. When reading the following, refer to DIAGRAM 1, the Oil Circulating Diagram on the following page.
The oil storage tank provides the supply of oil for combustion in the oil burner. In its normal condition, no. 6 fuel oil is very thick and heavy and is not easily pumped through the circulation system. For this reason the oil in the storage tank is heated. The temperature in the storage tank is usually maintained between 100˚and 130˚ Fahrenheit.
A suction cup circulates the oil throughout the system. Dirt and sediment are present in the fuel oil coming from the oil storage tank. The oil strainer removes most of these contaminants from the oil before the oil reaches the burner. 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 strainer or to perform other maintenance.
Preheaters are used to heat the oil further before the oil enters the burner for combustion. The oil is heated to between 160˚ and 180˚ Fahrenheit. Preheating makes it easier to pump the oil and also makes it easier to atomize the oil. The oil is metered into the burner where it is atomized by the spinner or atomizer cup. The atomized oil and air are mixed in the combustion chamber and burned.

The main fuel valve is electrically operated and will open or close the line leading to the atomizer of the oil burner. It will shut down the burner system if there is a failure of ignition or combustion.
Oil circulates through the system back to the storage tank through the oil return line. The normal oil pressure for no. 6 oil burners is between 30 and 50 psi. A back pressure relief valve is provided for safety if the pressure becomes too great. Additional heaters may be present in the return line to ensure that the oil is maintained at the proper temperature for easy circulation in the system.

OIL BURNER OPERATION
Combustion is the chemical union of the oxygen in the air with combustible elements in the fuel oil (hydrogen and carbon). The end result of this process is the production of heat energy. Oil firing equipment is used to liberate heat energy from the fuel oil. Oil burners are the principal components of the oil firing equipment and provide the means of supporting the process of combustion.
Carbon and hydrogen are the two principal elements of fuel oil. During the combustion process, the carbon content of the 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 as complete a combustion process as possible. This objective is met when the fuel oil combines with the greatest possible amount of oxygen.
Oil is a liquid fuel and as such will not burn. It must be changed to a gas or vapor and mixed with air if it is to support combustion. The oil burner is 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. This process of breaking down or atomizing the oil is necessary to ensure prompt ignition and rapid combustion. Although there are various types of oil burners, they all vaporize or atomize the oil before it enters the combustion chamber where it is mixed with air in predetermined proportions.
The low pressure oil burner uses a low pressure oil pump and mixes air and oil within the nozzle itself. In low pressure oil burners the oil and air mixture is delivered to the nozzle at a pressure from 1 to 15 psi, depending on the make of the burner. The air that contacts the oil prior to its leaving the nozzle is referred to as primary air. 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 low pressure burner is essentially unique and different from that of other manufacturers. Thus it is important that an operator of a low pressure oil burner system understand the functions of his/her particular system completely.
Oil burners require approximately 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. The mixture of air and fuel in the burner must be strictly controlled. Poor mixture could become an explosive mixture. During the process of combustion, one part of carbon unites with two parts of oxygen to produce carbon dioxide (CO2). Each time one pound of carbon is burned, 14,544 BTU of heat are liberated. Carbon dioxide is recognized as the end product of complete combustion. Should the fuel be raised to the correct temperature but not supplied with the proper amount of oxygen, carbon monoxide will be produced, and only 4,480 BTU of heat liberated. Carbon monoxide is recognized as the end product of incomplete combustion. In addition to being inefficient in the production of heat, the presence of carbon monoxide is highly dangerous.

If the proper amount of air has been thoroughly mixed with the oil, and the temperature of the flame is correct, the free carbon burns completely. A correctly adjusted oil burner flame will have an orange colored flame body with small red tips. These tips will be slightly cloudy. A red, smoky flame is an indication of a lack or air. A white, almost dazzling flame is an indication of a great amount of excess air. An insufficient air supply is one cause of dense, black smoke and soot; an excessive air supply can blow out the flame.
The oil spray entering the combustion chamber burns in suspension. If any part of the spray mixture that contacts the walls of the combustion chamber it will cause a smoky fire. Over a period of time carbon deposits may build up in the combustion chamber and cause a burner failure.
Insulating firebrick makes up the walls of the combustion chamber. Insulating firebrick is lightweight firebrick that becomes cherry red 15 seconds after the burner starts. The refractory material in the combustion chamber should be closed to the flame and the oil should be burned by the reflected heat. Reflected heat, which increases combustion efficiency, is heat that is reflected back into the combustion chamber and maintains the fire after the ignition is turned off.
Fuel oil comes in several grades, from range oil or no. 1 fuel oil, to diesel oil or no. 2 fuel oil; to the heavier no. 4, no. 5, and no. 6 fuel oils. No. 6 fuel oil (sometimes called “bunker C oil” or residual fuel oil) is the heaviest commercial fuel oil. When cold, it is almost of a solid consistency. It also contains the most sediment. Strainers are required in the oil line to filter out dirt and sediment. The oil in the storage tank is maintained in a preheated condition so that when it is required it can be moved through the piping to the oil burning unit. The storage temperature range is usually just a little above the 100˚ Fahrenheit mark. When using heavy oil such as no. 6 oil, combustion is improved if the temperature of the oil is further increased before atomization and combustion. The fuel temperature is raised to about 180˚ Fahrenheit before it enters the combustion process.
Several conditions can lead to improper operation of the oil burner system and to possibly dangerous situations.
1.A defective oil
2.A leaking seal on the oil pump shaft bearing may also cause oil to leak on the floor in front of the heating unit. The leaked oil could become ignited also.
3.Dirty or damaged nozzles or rotary cups can cause improper atomization. This will eventually lead to a carbon deposit
4.Blockage in the chimney or flue passage will cause the cellar or boiler room to become filled with smoke.
5.Water in the fuel oil or the wrong grade of fuel oil will cause improper atomization.
6.The protective relay is supported to shut down the oil burner if a flame is not established quickly. A delay in ignition is the most common cause for burner

One of the most dangerous conditions that occurs is when the oil burner goes into operation when the chamber is not hot and the source of ignition fails. If the chamber has not been preheated, the combustion chamber, the flue, and the chimney can become filled with vaporized oil fumes. These fumes may become ignited and cause a
OIL BURNER CONTROLS
The following information describes in more detail the various controls and devices on the oil burner and boiler. When reading the following refer to the DIAGRAM 2, Oil Burner Controls.
1.As described earlier, the fuel oil is stored in the oil storage tank.
2.The tank
3.The oil strainer separates dirt and sediment from the fuel oil coming from the storage tank.
4.The vacuum gauge readings indicate to the operator whether there is an obstruction in the suction line (e.g., the oil strainer is dirty and requires cleaning).
5.The oil preheater raises the temperature of the oil for easier pumping and atomization.
6.The main fuel valve is an electrically operated valve that will open or close the line leading to the atomizer of the oil burner. Under certain conditions it is activated by the primary control (#14). The burner
7.The atomizing cup (spinner) is a device that breaks up (atomizes) the fuel oil for proper combustion.
8.The vaporstat is a low pressure; pressure control mounted on the fan housing and will shut down
an oil burner if no air for combustion exists. A dangerous condition occurs when the oil is being
pumped to the combustion chamber and is not being atomized properly. An explosion may
result.
9.The mixture of fuel oil and air is ignited at first by a gas pilot or by electric ignition. After ignition, combustion is maintained by retained heat in the combustion chamber.

10.The photoelectric cell is a flame detection control. It is a device that will shut down an oil burner if a flame is not visible to the scanner or photoelectric cell. A dangerous condition will arise if oil is being pumped into the combustion chamber, but not burning. The atomized, unburned fuel could cause an explosion if a spark or other source of ignition occurred.
11.The aquastat operates the oil burner in the summer for domestic hot water needs.
12.The low water
13.The gauge glass is a device used to indicate the water level of a steam boiler. It is the most important control on the steam boiler. The gauge glass should have water visible when the boiler is in operation.
14.The stack switch (or primary control) is the main combustion controller. It will stop the oil burner and lock it out on safety in case of ignition failure or loss of flame in the combustion chamber. The stack switch operates when there is no heat in the smoke stack. A dangerous condition arises if the oil is being atomized and vaporized in the combustion chamber but no flame exists. A spark could cause an explosion in the combustion chamber.
15.The smoke alarm is a device mounted on the smoke stack or chimney. The smoke alarm will shut down an oil burner and put on an alarm if there is excessive smoke or if the fire is improper. A dangerous condition would exist if all the oil were not being burned or properly atomized, or too much oil was admitted to the combustion chamber. If the condition is not corrected, an explosion may occur. The smoke alarm is also a required combustion and air pollution control.
16.The boiler steam pressure gauge shows the steam pressure inside the steam boiler. The pressure gauge reads in psi (pounds per square inch). It is located on or near the top of the steam boiler. Normal steam pressure for low pressure boilers is less than 15 psi.
17.The safety or pop off valve is a device used to relieve excessive steam pressure. It is located on or near the top of a steam boiler.
18.The pressuretrol (Pressure Control) is an automatic electric control. It is an operating limit control and is a device that will shut down the oil burner when the steam pressure reaches a desired point. A dangerous condition could occur when the steam pressure is rising. If the pressure continued to rise unchecked, the boiler could blow up.
19.The manual reset pressuretrol is a control that will shut down a steam boiler if the pressure continues to rise above the operating pressure control setting. It will lock out the oil burner on safety in case the operating limit pressuretrol (#18) fails to stop the oil burner. This switch will not close again automatically. It must be rest manually.
