HIGHLY EFFICIENT CLEAN COMBUSTION BOILER FOR NEXT GENERATION USING ALTERNATED STEP COMBUSTION TECHNIQUE AND COMBUSTION METHOD USING SAME

摘要

The present invention relates to a clean combustion boiler, and more specifically relates to a technique of mixing two types of fuel through two or more nozzles. The fuel of a first primary nozzle uses a variety of renewable fuels such as conventional fossil fuels such as diesel or refined oil. A secondary fuel of a second nozzle is alcohol fuel mixed with more than 50% of water. These two nozzles are equipped with two different fuels with different characteristics. By means of the alternated step combustion method, various pollutants and toxic substances contained in the primary fuel, which provides a large amount of heat, are discharged to the air below a reference value for air pollution without using additional specific air pollution control devices, while an efficiency of the boiler is substantially improved compared to a conventional combustion boiler.;COPYRIGHT KIPO 2018
