Combustion of fats and oils

An electrical power generating system comprising a supply of potentially contaminated unrefined tallow or waste cooking oil potentially contaminated with hazardous material and consisting wholly or at least partly of animal fat, at least one compression ignition engine, means for admitting said tallow or waste cooking oil into the combustion chamber of said engine, means for creating an enriched oxygen atmosphere in the combustion chamber of said engine for combustion of said tallow or said waste cooking oil, said engine being configured and arranged to operate at a continuous power output that is higher than the continuous power output normally recommended by the engine manufacturer for operation with normal diesel fuel oil, and a generator connected to said engine.

A system for disposing of potentially contaminated unrefined tallow or waste cooking oil potentially contaminated with hazardous material and consisting wholly or at least partly of animal fat, said system comprising a supply of said tallow or said cooking oil, a compression ignition engine, means for admitting said tallow or waste cooking oil into the combustion chamber of said engine, means for creating an enriched oxygen atmosphere in the combustion chamber of said engine for combustion of said tallow or said waste cooking oil, said engine being configured and arranged to operate at a continuous power output that is higher than the continuous power output normally recommended by the engine manufacturer for operation with normal diesel fuel oil.

A method of combusting tallow in a standard high-speed compression ignition engine that is operating at its optimum speed, by introducing an enriched oxygen atmosphere into the combustion chamber of the engine and running the engine at a much higher continuous power output than would normally be expected from said engine.

A method of combusting tallow in a compression ignition engine wherein an enriched oxygen atmosphere is provided in the combustion chamber of the engine and wherein the engine is operated at a continuous power output that is higher than the continuous power output normally recommended by the engine manufacturer for operation with normal diesel fuel oil.

A method of combusting waste cooking oil consisting wholly or partly of animal fats and being potentially contaminated with hazardous material in a compression ignition engine wherein an enriched oxygen atmosphere is provided in the combustion chamber of the engine and wherein the engine is operated at a continuous power output that is higher than the continuous power output normally recommended by the engine manufacturer for operation with normal diesel fuel oil.

A method of combusting animal based oils or fats, in waste or contaminated state in a compression ignition engine wherein an enriched oxygen atmosphere is provided in the combustion chamber of the engine and wherein the engine is operated at a continuous power output that is higher than the continuous power output normally recommended by the engine manufacturer for operation with normal diesel fuel oil.

A method of combusting a mixture of animal or vegetable-based oil or fat in a compression ignition engine wherein an enriched oxygen atmosphere is provided in the combustion chamber of the engine and wherein the engine is operated at a continuous power output that is higher than the continuous power output normally recommended by the engine manufacturer for operation with normal diesel fuel oil.
