How does a oil fired fire work?

Answer 1

About the same way as a gasoline, or diesel, or wood fire works. Heat, with an oxidizer (air), and a fuel, in your question, the oil, mixed together properly produced a rapid oxidation of the components, the oil and air, to produce more heat, and a mixture of gasses. A discussion of this can be found in a good theoretical chemistry book.

Answer 2

Like in a boiler?

Oil is pumped from the oil tank to the boiler. At the boiler there is another pump which forces the oil through the atomizer (for want of a better simple word) which turns the oil into a fine misty spray as it blew into the fire box of the boiler. right as the oil comes out of the atomizer there is an electrical ignitor which ignites the oil the fire in turn heats the water in the boiler. The heated water then on demand is fed to the radiators to heat the house. And the water cools it returns to the boiler and the whole process starts all over again.
There is a good brief simple explanation of how an oil fired boiler works.

Answer 3

Oil-fired heaters and boilers are of the pot type or gun type.
With pot type heaters, oil is metered into a container within the combustion chamber and burns there. It has relatively low efficiency, and limited heat output.

Gun types have a high pressure pump that forces oil through an atomizer. This breaks the oil up into a spray. Oil is burned while suspended in air. Much more efficient, and capable of high heat output.

Answer 4

I wonder whether you meant "oil fired fire" or "oil fired boiler"
