Description

Eco-friendly low-nox burner {LOW NOx BURNER}

The present invention relates to an eco-friendly low-nox burner, and more particularly, by preheating fuel to a certain temperature and supplying it to the nozzle of the burner, the viscosity of the fuel is lowered, so that even when low-grade fuel containing bunker oil is used, the fuel is supplied to the nozzle. It relates to an eco-friendly low-nox burner configured to easily ignite and completely burn the fuel because the supply is smooth and the temperature of the fuel supplied to the nozzle is high.

Burners, industrial boilers, and agricultural hot air fans used in the waste plastic pyrolysis process are inexpensive and easy to control, so liquid fuels such as kerosene, diesel, and bunker oil are usually used. Among them, bunker oil is widely used because it is inexpensive.

A typical conventional burner has a cylindrical air tube, a fan that blows air necessary for combustion through the air tube, a filter that supplies fuel, a fuel supply device consisting of a pump, a valve, and a fuel tube, and the end of the fuel tube It has a configuration including a torch to which a nozzle for injecting fuel is attached as attached to the . A Fire Protector is attached around the nozzle to protect the flame.

The burner as described above is installed in a combustion chamber such as a boiler, and uses the heat of combustion of fuel by directly using hot air generated during combustion, or by heating a heat medium such as water, depending on the purpose.

As described above, in the conventional burner using liquid fuel, the fuel in the fuel tank is supplied to the torch as it is. In winter, when hot air is mainly used, the temperature is low and the viscosity of the fuel increases, so that the fuel is smoothly transferred to the nozzle of the torch. Not only is it not supplied, but when low-grade fuel such as bunker oil is used, the fuel temperature is low, so ignition and combustion do not occur well, and incomplete combustion may occur. In this case, there is a problem in that the combustion efficiency is low, so fuel is wasted, and the soot is generated and the soot is deposited inside the flue along with air pollution and the flue is clogged.

Bunker oil is a mixture of heavy oil and light oil, and is divided into 70% light oil, 30% heavy oil, Bunker A oil, 50% light oil, 50% heavy oil, Bunker B oil, and 30% light oil, 70% heavy oil, Bunker C oil. The fuel cost of this bunker oil is lower than that of diesel or kerosene, but it has a high flash point, so ignition does not occur well, and there are many cases of incomplete combustion, which causes a lot of soot, which causes air pollution problems. Therefore, bunker oil is limitedly used as fuel for large boilers equipped with preheating and thermal insulation facilities and large low speed diesel engines.

In the case of burners used in the pyrolysis process of waste plastics, agricultural boilers used in plastic houses, greenhouses, etc., low-grade fuels such as industrial waste, such as waste oil, are often used in addition to bunker oil to reduce fuel costs, and these low-grade fuels are ignited is more difficult

As described above, in the conventional burner using low-grade fuel, it is difficult to supply fuel to the nozzle of the torch due to the high viscosity of the fuel, and the low-temperature fuel does not easily ignite, so soot is generated, and the combustion efficiency is lowered. there was a problem
