Abstract
Disclosed is an apparatus and method for burning vegetable oil in a conventional furnace or boiler. The invention includes heating the vegetable oil fuel to a minimum fuel temperature prior to the delivery of the vegetable oil fuel to the furnace for combustion. The minimum fuel temperature can be calculated as the vegetable oil fuel's flash point minus the ignition energy of the furnace. The invention includes a preheater for heating the vegetable oil fuel and a computing device for controlling the heating and injection of the vegetable oil fuel into the furnace.
Claims20
An apparatus for modifying a conventional fossil fuel furnace/boiler to burn a vegetable oil comprising:
- a preheater for heating the vegetable oil fuel supplied to the furnace for burning;
- and
- a computing device connected to the preheater for regulating the temperature of the vegetable oil fuel supplied to the furnace.
An apparatus for modifying a conventional fossil fuel furnace/boiler to burn a vegetable oil comprising:
- a preheater for heating the vegetable oil fuel supplied to the furnace for burning;
- and
- a computing device connected to the preheater for regulating the temperature of the vegetable oil fuel supplied to the furnace,
- wherein the computing device directs the preheater to heat the vegetable oil fuel to at least a minimum target temperature;
- and
- wherein the minimum target temperature is the difference, plus or minus 5° C., of the fuel flash point of the type of vegetable oil fuel used minus an ignition energy of the furnace/boiler.
A method of modifying a conventional fossil fuel furnace/boiler to burn a vegetable oil comprising the steps of:
- heating the vegetable oil fuel supplied to the furnace for burning;
- detecting the temperature of the vegetable oil fuel supplied to the furnace for burning;
- determining a minimum target temperature corresponding to a type of vegetable oil fuel, wherein the minimum target temperature is the difference, plus or minus 5° C., of the fuel flash point of the type of vegetable oil fuel used minus an ignition energy of the furnace/boiler;
- and
- regulating the vegetable oil fuel supplied to the furnace for combustion to a temperature corresponding to the minimum target temperature.
