Triglyceride oils, primarily in the forms of waste grease from restaurants, renderings or other biogenic resources may be and are used as a fuel in a wide variety of applications when such systems are modified for the triglyceride feedstocks. ASTM D7666 Triglyceride Burner Fuels defines neat (unblended) fuels for narrow applications. Most applications that draw on triglycerides as a fuel source, blend the biogenic triglycerides with petroleum based fuels primarily in boiler applications. This work item is introduced to address the need for broader application, including allowing blending, of these types of fuels and provide clarity to the market and policy makers using them for fuel preparation, quality checking, bid and purchasing contracts.
triglyceride based fuels are being used in applications beyond waste oil burners and often are blended with a petroleum product for flame stabilization. A new standard is needed to allow blending and broader applications.
