ABSTRACT:
A preheater block for a multi oil furnace is disclosed wherein the metallic preheater block is formed with a separate heater chamber housing a heating element to provide conductive heat throughout the preheater block which is provided with a first flow path defining multiple passes through the preheater block to raise the temperature of the flow of used oil therethrough to a predetermined level. An oil flow regulator is coupled to the first flow path to permit a manual regulation of the rate of oil flow through the preheater block after the used oil has attained the predetermined temperature. A second flow path is defined within the preheater block to allow a flow of compressed air therethrough to reach substantially the same predetermined temperature as the used oil.
