Emulsion fuels are typically made by mixing water with a petroleum or bio-based fuel; usually with diesel or fuel oil of various grades. Additives are required to keep the emulsion in suspension, and an agitation device is required to create the emulsion. Until the development of FRI’s R-Fuel, emulsion fuels have had a very limited storage life, and were not miscible with regular fuel. The lack of stability incurs the risk of introducing water into the engine or fuel system components.
Prior to the development of FRI R-Fuel technology, use of emulsion fuels resulted in a net loss in power. This is because the added water must be vaporized in combustion which consumes energy. Since the available energy of the unit volume of fuel is reduced by the displacement of water for fuel, and the power produced is further reduced by the heat of vaporization of the added water, emulsion fuels have historically produced 80% or less power by volume than their constituent fuel.
This critical problem was corrected with the development of FRI’s R-Fuel which actually increases the energy extracted from fuel in both internal and external combustion engines. This is caused by FRI’s exclusive process and our additive. In internal combustion engines, FRI R-Fuel’s uniquely high burn efficiency yields an increase in power per volume of fuel over the base fuel, reducing fuel procurement and improving power and dramatically reducing emissions.
FRI R-Fuel changes emulsion fuel practicability because it is stable, miscible, and very importantly because the R-Fuel emulsion droplets are extraordinarily small (under 200 nm). The unique R-Fuel emulsion droplet is formed with a tiny water droplet at its center. During combustion, the water droplet vaporizes before the fuel vaporizes, disbursing micron scale fuel droplets which permit very high combustion efficiency.
In external combustion devices, R-Fuel’s uniquely high burn efficiency also yields a more efficient burn, allowing near elimination of excess air. This saves wasted heat and eliminates excess N2, reducing exhaust pollutants and extending heavy fuel oil by up to 40 percent while maintaining thermal output, and dramatically reducing waste products.
Most internal combustion engines do not extract the full energy available from the fuel because of limited burn time in the combustion chamber, and the limited efficiency (large droplet size) of the vaporization of the fuel. The smaller the fuel droplets are the more surface area for combustion. Thus, in typical engines, a significant amount of the thermal energy of the fuel is lost as unburnt fuel, and becomes pollutants in the exhaust gas.
With our system, not only do we not lose energy, there is actually a net gain versus regular fuel, we encourage you to contact us for more details and to see how your company can benefit from using our technology, saving Energy and the Environment one project at a time.
