FUEL OIL SYSTEM

A furnace provides steady burning of fuel. When burning fuel the following characteristics of it should be taken into consideration: viscosity, specific gravity, flash point, pour point, heating value and some others.

A furnace fuel oil system consists of a fuel tank from which fuel is drawn through a strainer by a pump. This pump delivers fuel under pressure through a filter and a heater to the burners. In the burners it mixes with air and is ignited inside the furnace.

The complete furnace fuel oil system consists of:

1. Oil fuel filling system – to replenish the fuel tanks.

2. Suction system – to allow any tank to be used and for transferring fuel from remote tanks.

3. Discharge system – to deliver fuel under pressure to the burners.

Fuel is burnt in the furnace in suspension. Therefore, a burner used for atomization is a very important element in fuel burning equipment.

Although there are a lot of types of burners they work on the same principle.

The fuel is heated to the burning temperature, which reduces viscosity and then delivered under pressure to the burner body. The fuel passes through the holes which give it a rotary motion and then through the orifice in a conical spray – to the furnace.
