Abstract
Heated fuel-oil is injected into an open-ended mixing chamber simultaneously with a jet of water so that an intimate mixture of fuel-oil and water is formed. This mixture is ignited and sufficient air is supplied to support combustion. To clean and pre-heat the fuel, it is injected into a tank partly filled with hot water, through which the oil rises to form a separate layer in the top of the tank, from where it is withdrawn.
Claims4
A method of burning fuel-oil comprising the steps of:
- injecting fuel-oil into a tank partly filled with hot water maintained at approximately 90.degree.C;
- allowing the fuel-oil to rise through the hot water to form a separate layer of fuel-oil in the top of said tank while preheating said fuel-oil to a temperature of approximately 90.degree.C;
- withdrawing fuel-oil from said layer;
- heating the thus withdrawn fuel-oil to a temperature of approximately 300.degree.C;
- injecting the heated fuel-oil into an open-ended mixing chamber of a combustion chamber while simultaneously injecting into said mixing chamber a separate jet of water so that an intimate mixture of fuel-oil and water is formed;
- and
- supplying to the open end of said mixing chamber sufficient air to support combustion of the said mixture.

A method of burning fuel-oil comprising:
- preheating fuel-oil to approximately 90.degree.C while freeing said fuel-oil from particles and pockets of water;
- passing the preheated fuel-oil, free from particles and pockets of water, to a burner assembly;
- heating said fuel-oil in said burner assembly to approximately 300.degree.C;
- and
- ejecting the hot fuel-oil from said assembly simultaneously with a separate jet of water which mixes with the fuel-oil.
