摘要

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.
