Chapter 2—Heating Oil and Its Properties 2-15 You will be transferring contaminates that caused the problem in the first place. It will take surprisingly little time to make the nice new tank as dirty as the old one. If you are installing (or maintaining) an outdoor, above ground tank, it is recommended you paint it a light color to reflect the light. This will help keep the tank cooler and minimize moisture condensation inside the tank. Also, there are several types of tank sheds available, Figure 2-4. They minimize water build-up and frozen lines as the tank temperature is steadier. Keep the tank full Topping off oil tanks, especially outdoor above ground tanks in the spring, helps prevent condensation—the less air in tank, the less condensation. Bioheat fuel® Biofuel is a renewable, biodegradable combustible liquid fuel. Biofuel is manufactured by processing vegetable oils such as soy and rapeseed (canola). It is also made from waste cooking oils and trap grease, tallow, and animal fats such as fish oil. Biofuel has an ASTM specification D6751 for pure biofuel (B100). It has 10- 12% oxygen, so it will increase excess air to the flame. Its heating value is 125,000 Btu per gallon. It has a slightly higher density and higher cloud and pour points than #2 oil. Bioheat fuel® is a blend of 95% or more If you are installing (or maintaining) an outdoor, above ground tank, it is recommended you paint it a light color to reflect the light. This will help keep the tank cooler and minimize moisture condensation inside the tank. Also, there are several types of tank sheds available. They minimize water build-up and frozen lines as the tank temperature is steadier. #2 oil and 5% or less B100 biofuel. We call a 5% blend B5. Bioheat can be used in oilburners with little or no modifications to the equipment or operating practices. While flashpoint is higher, ignition with blends of 5% or less is no problem. The viscosity is higher, yet still within ASTM limits for heating oil; but flow rate and atomization are similar. Bioheat will create slightly less deposits on the heat exchanger thanks to the reduced sulfur levels. Bioheat fuel® has strong public appeal as a renewable fuel. It has good lubricity that will help with low sulfur fuels. It increases our fuel source diversity, reducing dependence on foreign crude and is a potentially huge market for American agriculture. Summary Most of our fuel problems are created in the customer’s tank and heating system long after delivery. Oilheat reliability is dependent on the technicians in the field, keeping customer’s systems operating at peak safety, dependability, and efficiency. Chapter 2 Heating Oil
