LOW COST BIOHEATING OIL APPLICATION.
The report describes primarily the results of combustion tests carried out with a soy methyl ester (SME) that can be considered as a biofuel that does not quite meet the ASTM D 6751-02 specifications for biodiesel. The tests were performed in a residential boiler and a commercial boiler. Blends of the SME in distillate fuel (home heating fuel or equivalently, ASTM No.2 fuel oil) were tested in both the boilers. Similar tests had been conducted in a previous project with ASTM biodiesel blends and hence provided a comparison. Blends of the SME in ASTM No.6 oil (residual oil) were also tested in the commercial boiler using a different burner. Physical properties of the blends (in both the petroleum based fuels) were also measured. It was found that the SME blends in the distillate burned, not surprisingly, similarly to biodiesel blends. Reductions in NOx with blending of the SME were the most significant finding as before with biodiesel blends. The blends in No.6 oil also showed reductions in NOx in the commercial boiler combustion tests, though levels with No.6 blends are higher than with No.2 blends as expected. A significant conclusion from the physical property tests was that even the blending of 10% SME with the No.6 oil caused a significant reduction in viscosity, which suggests a potential direction of application of such blends.
