How are oil burner nozzles rated?
Nozzles are generally rated at 100 psi, and that is the pressure that most residential-style oil burners run at, but not all. It also has an 80-degree spray angle. That is the angle at which the spray comes out of the nozzle. The smaller the angle, the narrower the spray pattern.
What are the three numbers on an oil nozzle?
On oil nozzles, the first number is gallons of oil per hour at 100psi. The second number is the apex angle (30° to 90° arc) of the oil spray cone. The letters designate the fill of the spray cone: A or H = hollow, B or ES = solid, SS = semi-solid, W = multipurpose.
What is the difference between a hollow core and a solid core oil nozzle?
Hollow cone nozzles generally have more stable spray angles and patterns under adverse conditions than solid cone nozzles of the same flow rate. This is an important advantage in fractional gallonage nozzles where high viscosity fuel may cause a reduction in spray angle and an increase in droplet size.
Can you clean a oil burner nozzle?
Drop the nozzle into the container filled with kerosene. The nozzle itself will need to set for about a half an hour to make sure to get all of the soot and debris off of it. Once you have taken the nozzle out of the kerosene get out your rag and wipe it clean.
What is the typical oil pressure for a gun type oil burner?
80 – 130 psi
The oil pressure for a residential gun-type burner is usually 80 – 130 psi. Industrial and commercial burners need more than 100psi.
What is a Tiger loop for oil furnace?
The Tiger Loop is a lifting and de aerating device that improves performance and provides convenience to diesel (oil) boiler installations. The Tiger Loop is installed next to the boiler and still has a single fuel line from the fuel tank to the Tiger Loop incorporating a filter and fire stop valve.
What are the numbers on an oil burner nozzle?
Oil Burner Nozzles by Delavan. On oil nozzles, the first number is gallons of oil per hour at 100psi. The second number is the apex angle (30° to 90° arc) of the oil spray cone. The letters designate the fill of the spray cone: A or H = hollow, B or ES = solid, SS = semi-solid, W = multipurpose. We also stock nozzle valves,…
What kind of energy does a oil nozzle need?
Energy is required to break up the oil into droplets. The energy is supplied by the fuel unit delivering oil to the nozzle from 100-150 PSIG for most residential applications and up to 300 PSIG for commercial applications. The nozzle, through the swirl slots, swirl chamber and orifice converts the energy from pressure to velocity.
What’s the difference between A and B nozzles?
The difference between an A nozzle and a B oil burner nozzle is that the B produces a solid rather than hollow core spray pattern. B nozzles are more-often used on larger or industrial oil burners. In my opinion an A nozzle will give an easier-to-set and cleaner flame in a small oil burner.
What is the firing rate of an oil burner?
This is the nozzle firing rate – the number of gallons per hour of No. 2 heating oil that the nozzle will pass, assuming that the oil burner fuel unit is set to 100 psi. Our oil burner nozzle photo shows you what an oil burner nozzle looks like.
