WATER SERVICES LTD'S WSF E-2650 EMULSION
WSF E-2650 emulsion is a water-in-oil emulsion fuel consisting of from 5 percent to 15 percent water dispersed as droplets in a continuous oil phase. The key to achieving maximum combustion with this fuel is producing water droplets in the range of 5 microns to 20 microns in diameter within the oil. This is accomplished by introducing a small amount of WSF E-2650 .to control water droplet size and prevent coalescence. Proper mixing and proportioning of the water, oil and WSF E-2650 creates a very stable emulsion that is ready to burn. Figure I compares the size of a typical fuel oil droplet sprayed into the combustion chamber with a WSF E-2650 emulsified fuel droplet containing many water droplets of 5 microns to 20 microns in size. A typical burner atomizer produces a spray of fuel oil droplets around 100 microns to 200 microns in diameter, depending on fuel quality and atomizer design. Typically, the larger fuel droplets do not completely burn, leaving unburned carbon to collect on heat transfer surfaces and escape as particulate matter in the exhaust gases. This reduces overall thermal efficiency. |
