Description

Liquid or gas fuel's perfect spreading, how increase heat capacity and that's construction by high temperature heating}

.

The present invention burns by heating the fuel to 800 ~ 1000 degrees or more liquid and gaseous fuel in order to solve the above problems

The fuel is injected from the nozzle by heating it to a boiling point of 800 ~ 1000 degrees or more by winding the fuel pipe one or more times or by heating other fuel on the edge of the flame that is injected and burned. Fuel emitted from the first nozzle uses a small amount of heat from the combustion to heat the fuel, so the heat required to heat the fuel is 800 ~ 1000 degrees, but the heated fuel is injected at high temperature and high pressure, thus expanding the fuel particles. Are finely divided and the combustion heating surface area is high, resulting in high thermal efficiency and low fuel consumption. In addition, the air supply is not sporadically sprayed from the injection plate during high temperature combustion, and the oxygen supply required for high temperature combustion is appropriately reduced by collision, horizontal, and rotational injection so that the pollutants CO, HC, NOx, etc. are significantly reduced, thereby improving the combustion efficiency.

Hereinafter, described in detail by the accompanying drawings as follows.

2 shows that when fuel is injected into the fuel pipe 6 of the barna at a constant pressure, the fuel is injected from the vane nozzle part 8 and ignited by the ignition rod 3 so that the fuel is combusted. At this time, the fuel passing through the pipe in the flame portion is heated and after a certain time the fuel pipe of the flame portion is heated to a high temperature (800 ~ 1000 degrees), the fuel is heated above the evaporation temperature in a closed space nozzle ( In 8), when the fuel is injected, the fuel itself becomes a heating element and emits high temperature heat and is completely burned. In addition, since the fuel particles are undifferentiated during the high-temperature fuel injection, the heat generation and the light emitting area are widened, so that the heat amount is increased by three times or more than the low temperature combustion. In addition, since the fuel is completely burned at a high temperature at a high temperature, pollutants are reduced, and heat of the fuel pipe is heated by heating the fuel pipe, thereby increasing combustion efficiency. 3 to 5 is a method of supplying air when combustion of high-temperature fuel, and (10) of FIG. 3 is a collision injection method for fuel injection, and pressurized air around the nozzle without sputtering injection when air is injected in (9). Impingement high-speed injection at a certain angle of the figure to properly supply the oxygen required for high-temperature combustion and widen the light emitting area by the segmentation of fuel particles during combustion. Figure 4 (12) is to form an air mat in the flame portion (2) by the horizontal injection of air to block the high temperature direct contact in the combustion furnace to protect the combustion furnace and to prevent the fuel from directly contacting the fuel heating pipe It prolongs fuel combustion time, prevents the spread of combustion heat, preserves it, and uses the stored heat to increase the combustion effect. 5 (13) causes a rotation phenomenon because it is made in the form of a screw when supplying air. Therefore, unbalanced temperature distribution in the furnace due to high temperature combustion and NOx generation due to high temperature combustion are prevented.

As described above, the present invention is a method of burning a gas and a liquid fuel by heating the fuel to a high temperature to burn the fuel so that the fuel passes through the primary combustion flame portion to burn the fuel at a high temperature and supply the air. By effectively burning the fuel, the complete combustion of the fuel improves the thermal efficiency and reduces the fuel by 60 ~ 70%. It also reduces the generation of pollutants such as CO, HC and NOx.
