Characteristics 1. Non-separable of fuel and water The emulsion fuel mixed a little additive into oil and water does not separate in any condition of heating or cooling. 2. Stabilized fuel property The emulsion is stable in any condition of temperature from -7 to 100. The fuel property for combustion is maintained. It leads to complete combustion. 3. Inorganic components (a) A conventional additive is composed of organic constituents that generate harmful pollutants for the combustion. (b) It is unstable that the additive using surfactants often separate oil and water at 50 to 60. (c) New additive produces emulsion fuel with 30% oil and 70% water in W/O condition though the conventional additive produces the fuel in O/W condition. * W/O is the state of water particles in oil. * O/W is the state of oil particles in water. 4. No corrosion to pipes and inner walls (a) On the conventional emulsion the corrosion is often generated because of attacking water content to inner pipe directly. It is serious problem to keep a plant in good condition. (b) New emulsion of W/O type does not corrode pipes with attacking water. 5. Decreasing the combustion air (a) More than enough air on combustion increases the heat loss in the furnace. (b) An air pollutant of NOx is generated by nitrogen in the air with the thermal reaction. NOx concentration is increased with the excess air and flame temperature exponentially. (c) Low air ratio and complete combustion are possible using the emulsion fuel. It is available to reduce the heat loss and NOx. 6. Combustion improvement (a) Improvement of combustion leads to the high fuel consumption rate. (b) No smoke in funnel and no deposit on heat-transfer pipe, those will be easy to operate and simplification to maintain plants for a long time. 7. Applicable oils B and C (JIS) type HFO, Crude oil(petroleum), Sand oil, Waste oil, etc. 8. Low setup cost (a) The costs of plant are shown in table below Table. Cost of Plant Fuel consumption (L/h) Cost (JPY) 5,000 10,000,000 10,000 20,000,000 20,000 30,000,000 (Not include setup work and fitting cost) (b) This plant can setup on the conventional plant without reconstruction.

(A) Fuel saving rate (ratio of fuel consumption) 1 HFO 100% 2 Emulsion 88% 12% (Fuel saving rate) (p-2) 12% fuel saving is obtained. Example: In case of using a boiler of an independent power plant at 5,000L/h (Fuel, 1L= 51.5) for 360 days. 1 Fuel consumption by year: 5,000L 24h 360days = 43,200,000L/year 2 Fuel saving: 43,200,000 0.12 = 5,184,000L/Year 3 Cost of fuel saving: 51.5( /L) 5,184,000L = 266,976,000yen However, the cost of additive by year is 58,060,800yen. Therefore net fuel saving cost : 266,976,000yen - 58,060,800yen = 208,915,200yen (B) Reduction of CO2 It will be sure that CO2 reduction rate is 12% since the fuel saving rate is 12%. (C) Component analysis of fuel The tables of components are described in the Japanese patent (P4) and USA (No.5, Table2). The result of analysis by Physical & Chemical Analysis Center of NKKK was made use of the application for patent. Samples are HFO and its emulsion fuel. Analyzing method is in accordance with the standard of JIS. The analyst of the center said that it was unprecedented that such an analysis for water-oil emulsion could be performed. Because the conventional emulsion was so unstable that the emulsion state could not be analyzed. There is no description of the component analysis for emulsion fuel in patents. We must keep a close watch on one patent that was plagiarized our patent, we will not yet lay claim to the patent. (D) Experiment of emulsified state 1 We can make the water-fuel emulsion with the additive easily and carry out a experiment of emulsion state with boiling the emulsion and watching a separation of the emulsion. It takes a time of 30 minutes. We will give you the samples measured in the experiment to recognize the sample not to change the state for the time. 2 The oil and water are mixed at the ratio of 50% to 50% after heating them respectively. 3 We must measure the samples prepared by you to avoid any doubt in the experiment. If we use the samples prepared ourselves, you will doubt the results as if the samples were magical. We might prepare the samples only if you trust us. 4 If you wish to carry out the experiment on your factory site, your heater (gas or electric) needs to be used. - 7 -
