WASTE COMBUSTION SYSTEM USING ELECTROMAGNETIC SPECTRUM

The present invention relates to a waste combustion system using an electromagnetic spectrum. It is possible to continuously supply an appropriate amount to a combustor while storing a solid fuel, which is produced by forming crushed life waste in a cylindrical shape or a polygonal shape in a molding device, in a fuel hopper. In a state in which a solid fuel is complexed, a small amount of water is supplied to be separated into hydrogen and oxygen, so that hydro-combustion that assists combustion is performed. The combustion is accelerated while flames are concentratedly combusted at the center of a combustion furnace due to magnetic force by an electromagnet and a permanent magnet in the combustor. A combustion space of a hemispherical shape is formed on an upper portion of the combustion furnace to allow heat and light reflected on an inner surface to be concentrated in a center to be intensively combusted by a focus. An electromagnetic spectrum is installed in the combustion chamber ...

Induced-draft low swirl burner for low NOx emissions

A burner for use with an induced draft furnace and which satisfies reduced nitrous oxide (NOx) emission standards is disclosed. The burner may employ a mechanical swirler that introduces a rotational vector to the emitted air and fuel mixed by the burner. By introducing the rotational vector, the resulting flame is more stable and sustainable even with the relatively low air flow afforded by an induced system. Such flame stability can be enhanced by positioning the burner directly within an inlet to a heat exchanger and manufacturing the inlet with reception surfaces that form a frusto-conically shaped flame expansion zone. In doing so, a secondary source of air is avoided and NOx emissions are reduced.
