Field experience with Bioheat® fuel (blended heating oil and biodiesel) has been overwhelmingly positive. A recent service organization survey conducted by NORA and Brookhaven National Laboratory observed that some 35,000 buildings are currently using Bioheat® containing more than 5% biodiesel without incident.
It is important to note that biodiesel is a specific product that meets American Society for Testing and Materials (ASTM) D6751 specifications and has well-established product characteristics designed to ensure that it can be safely and efficiently blended into heating oil and diesel. Biodiesel meets detailed fuel property specifications within ASTM D6751. ASTM consists of experts from petroleum companies, equipment manufacturers and research organizations. In-spec biodiesel has undergone rigorous material compatibility, combustion, lubricity, field testing, and stability studies as part of the long ASTM approval process. Continue reading
