Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be used as a fuel for heat treatment and as a fuel for an internal combustion engine, because it can completely burn high-viscosity, high-flash point emulsified fuel or highly hydrated oil or waste oil with a simple device. Replenishment of oxygen necessary for combustion by aqueous gasification of medium moisture makes it possible to increase the combustion speed at a low air ratio and achieve an average distribution flame, so that harmful exhaust gases such as nitrogen oxides and carbon monoxide can be reduced. Furthermore, the combustion of hydrogen generated by gasification and the combustion with a low air ratio prevent the cooling of the flame, reduce the loss of calorific value, greatly reduce fuel consumption, and save the environment,
Can be used as a clean recycled fuel.

2. Description of the Related Art Conventionally, in the process for producing Lesnox fuel, the ratio of oil 7: water 2: interfacial agent 1 is at the limit of water addition. If water is added more than this, the oil-water separation and the latent heat of evaporation increase, and there is a problem that it is not practical. Furthermore, the structure of the conventional burner is composed of a fine hole fuel spray device, a combustion air blower, and an ignition device, and the spray particle size is large. Excess air is required for complete combustion, so the combustion flame temperature and heat value are lost. There is a problem that thermal NOx is generated in large quantities when the temperature decreases and combustion at a higher temperature occurs.

The purpose of this is to make the gas turbine generator possible to operate stably, increase the output and clean the exhaust gas.

[Function] An oil fuel and tap water are measured by a measuring instrument, and the mixed oil is mixed into a mixing and circulating tank at a mixing ratio of oil: water = 1: 1 to a mixed oil / water mixture, and then circulated by a circulation pump (gear pump or cascade pump). Pressure to the hydraulic rotary crushing and decomposing device, and furthermore, liquid molecules are super-micro-
It has the effect of producing a long-term stable water emulsion fuel by ionization. Furthermore, in order to atomize the fuel, a high-pressure air and fuel are laminar-flowed and a high-speed swirling and stirring center nozzle and a swirling slit are provided on the outer periphery of the center nozzle to externally mix to increase the surface area of the fuel, increase the spraying speed, and reduce high-speed fine particles Contact is made in a high-temperature multistage cylindrical staged combustion zone to promote gasification, complete combustion is completed in the latter stage combustion zone, and nitrogen oxides are reduced by combustion gas convection in the furnace. Further, when the emulsion fuel produced by the above-mentioned apparatus is used as a fuel for a gas turbine engine, there is an effect that the efficiency can be improved by reducing NOx by optimizing the combustion temperature and increasing the specific gravity of the exhaust gas by increasing the specific gravity of the exhaust gas by gasifying the moisture.

The mixture is passed, and further, 0.05% of the total amount of the auxiliary agent is added by the auxiliary agent adding device 4 to stabilize the emulsion, and the automatic control device 5 is operated. The produced fuel is stored in a reserve tank 6 and used while returning surplus fuel to the reserve tank by a refueling pump 7 that circulates and feeds the fuel to combustion equipment. Further, the emulsified fuel and the high-pressure air compressed to 2 to 7k by the air compressor 9 are fed into the externally-mixed high-pressure two-fluid swirling atomizer 8 of the water emulsion fuel produced by this apparatus, and the ultrafine fuel and water Was gasified into contact with the multi-stage cylindrical combustion cone 10 and completely burned in the air or in a furnace. Further, the fuel injection nozzle 12 was added using the water emulsion fuel as the fuel for the gas turbine cogeneration, and the control device was changed to a control device capable of simultaneously and independently using the pure fuel and the water emulsion fuel.
