Definitions
- This invention relates to the field of waste incineration and more particularly to a system, method and apparatus for using a gas here within referred to as Magnegas in the process.
- Garbage and waste incineration is a widely accepted alternative to landfill for many reasons, including the amount of space taken by a land fill, transportation to the land fill, soil and water table pollution from leaching of toxins into the soil and aquifer beneath the land fill, various aromas, wild life attracted by a land fill (e.g. rats, birds), release of methane gas, and the overall unsightliness of a land fill. Furthermore, even well lined landfills run the risk of soil and water contamination due to earth shifting or sink holes.
- An incinerator is a system that burns waste material, typically including organic substances. The incinerator converts the waste material into ash, flue gas and heat and the heat is often used to generate power. Most incinerators require systems to clean the flue gas of the ash and other pollutants.
- Incinerators have a bad reputation and municipalities are reluctant to provide permits for incinerators due to the high levels of emissions which typically require scrubbers in an attempt to clean the exhausts of combustion. For this reason, there is a lower level of usage of incinerators, leading to many of the above mentioned problems related to landfill.
- flue gases need to reach a minimum temperature to ensure proper breakdown of toxic organic substances and must sustain that temperature for a period of time, usually a few seconds.
- European standards require that the flue gases achieve a temperature of at least 1,560 F. for at least 2 seconds.
- the incinerators require forced air convection systems and, for some waste, injection of auxiliary fuels such as oil or natural gas, etc.
- dioxin is believed to be a serious health hazard.
- the molecular ring of dioxin must be exposed to a sufficiently high temperature so as to trigger a thermal breakdown of the molecular bond. This is one reason why European standards require achieving of a flue temperature of 1,560 F. for at least 2 seconds, often requiring injection of additional fuel into the burning process.

Description
- This application claims the benefit of U.S. provisional application no. 61/982,568 filed on Jan. 18, 2008, and European application no. 08150277.5 filed on Apr. 22, 2014, the disclosure of which are incorporated by reference.
- This invention relates to the field of waste incineration and more particularly to a system, method and apparatus for using a gas here within referred to as Magnegas in the process.
- Garbage and waste incineration is a widely accepted alternative to landfill for many reasons, including the amount of space taken by a land fill, transportation to the land fill, soil and water table pollution from leaching of toxins into the soil and aquifer beneath the land fill, various aromas, wild life attracted by a land fill (e.g. rats, birds), release of methane gas, and the overall unsightliness of a land fill. Furthermore, even well lined landfills run the risk of soil and water contamination due to earth shifting or sink holes. An incinerator is a system that burns waste material, typically including organic substances. The incinerator converts the waste material into ash, flue gas and heat and the heat is often used to generate power. Most incinerators require systems to clean the flue gas of the ash and other pollutants.
- Incinerators have a bad reputation and municipalities are reluctant to provide permits for incinerators due to the high levels of emissions which typically require scrubbers in an attempt to clean the exhausts of combustion. For this reason, there is a lower level of usage of incinerators, leading to many of the above mentioned problems related to landfill.
- For most waste that includes organic materials, flue gases need to reach a minimum temperature to ensure proper breakdown of toxic organic substances and must sustain that temperature for a period of time, usually a few seconds. For example, European standards require that the flue gases achieve a temperature of at least 1,560 F. for at least 2 seconds. To assure such temperatures, the incinerators require forced air convection systems and, for some waste, injection of auxiliary fuels such as oil or natural gas, etc.
- One particularly bothersome pollutant from incineration is dioxin. Dioxin is believed to be a serious health hazard. To breakdown dioxin, the molecular ring of dioxin must be exposed to a sufficiently high temperature so as to trigger a thermal breakdown of the molecular bond. This is one reason why European standards require achieving of a flue temperature of 1,560 F. for at least 2 seconds, often requiring injection of additional fuel into the burning process.
- What is needed is an incineration system that uses Magnegas to facilitate proper combustion and/or secondary combustion to limit pollutants that are emitted into the atmosphere.
- A system for incinerating waste using Magnegas either in the primary burn process to achieve higher flue temperatures, in a secondary after-burn process to reduce pollutants, or in both the primary burn process and after-burn process. In some embodiments, Magnegas is combined with another fuel such as oil or natural gas for the desired burn characteristics or for economic reasons.
- The invention can be best understood by those having ordinary skill in the art by reference to the following detailed description when considered in conjunction with the accompanying drawings in which:
-
FIG. 1 illustrates a schematic view of an exemplary system for incinerating waste. - Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference numerals refer to the same elements in the figure.
- Throughout this description, the apparatus is described as a system for incinerating waste, in which, the term “waste” is meant to be the most generic interpretation as possible, in which, the material being incinerated may include any type of materials often found in municipal waste, including, but not limited to, plastics, cardboard, unused foods, metals, wood, vegetation, baby diapers, etc.
- Referring to
FIG. 1 , an exemplary system for the production of a combustible gas, herein called Magnegas, which is used herein in combustion related to incineration. This is but an example of one system for the production of Magnegas, as other such systems are also anticipated. Examples of fully operational systems for the production of Magnegas can be found in U.S. Pats. No. 7,780,924 issued Aug. 24, 2010, U.S. Pat. No. 6,183,604 issued Feb. 6, 2001, U.S. Pat. No. 6,540,966 issued Apr. 1, 2003, U.S. Pat. No. 6,972,118 issued Dec. 6, 2005, U.S. Pat. No. 6,673,322 issued Jan. 6, 2004, U.S. Pat. No. 6,663,752 issued Dec. 16, 2003, U.S. Pat. No. 6,926,872 issued Aug. 9, 2005, and U.S. Pat. No. 8,236,150 issued Aug. 7, 2012, all of which are incorporated by reference. The production of such a gas (e.g. Magnegas) is performed within the plasma 18 of a submerged electric arc. - A
feedstock 22 is circulated within atank 12 and is exposed to the plasma 18 of an electric arc between twoelectrodes 14/16, causing thefeedstock 22 to react and release gas. The arc is powered by a source ofelectric power 10. - One
exemplary feedstock 22 is oil, and more particularly, used vegetable or animal oil such as that from deep-fat fryers, etc. Of course, any oil is anticipated, including unused vegetable oil, oil from animal fat, used hydrocarbon-based oil, unused hydrocarbon-based oil, etc. - Any
feedstock 22 is anticipated either in fluid form or fluid mixed with solids, preferably fine-grain solids such as carbon dust, etc. - In one example, the
feedstock 22 is vegetable oil and theelectrodes 14/16 are carbon, the oil molecules separate within the plasma 18 of the electric arc into agas 24 referred to here-within asMagnegas 24, typically including hydrogen (H2) and carbon monoxide (CO) atoms, which separated from thefeedstock 22 for collection (e.g. extracted through acollection pipe 26. This gas 24 (e.g. Magnegas) is similar to synthetic natural gas or syngas, but the gas produced though this process behaves differently and produces a higher burn temperature. In embodiments in which at least one of theelectrodes 14/16 that form the arc 18 is made from carbon, the electrode(s) 14/16 and serves as a source of charged carbon particles (e.g., carbon nanoparticles) that become suspended within thegas 24 and are collected along with thegas 24, thereby changing the burning properties of the resultinggas 24. - In examples in which the
feedstock 22 is a petroleum-based liquid, the exposure of this petroleum-basedfeedstock 22 to the arc (as above) results in a gas that includes polycyclic aromatic hydrocarbons which, in some embodiments, are quasi-nanoparticles that are not stable and, therefore, some of the polycyclic aromatic hydrocarbons will form/join to become nanoparticles or a liquid. Therefore, some polycyclic aromatic hydrocarbons as well as some carbon particles/nanoparticles are present in the resultinggas 24. In some embodiments, some of the carbon particles or nanoparticles are trapped or enclosed in poly cyclic bonds. Analysis of the producedgas 24 typically includes polycyclic aromatic hydrocarbons that range from C6 to C14. The presence of polycyclic aromatic hydrocarbons as well as carbon particles or nanoparticles contributes to the unique burn properties of the resultinggas 24. This leads to higher burning temperatures. - In another example, when the
feedstock 22 is petroleum based (e.g. used motor oil) and at least one of theelectrodes 14/16 are carbon, the petroleum molecules separate within the plasma of the electric arc 18 into agas 24 that includes hydrogen (H2) and aromatic hydrocarbons, which percolate to the surface of thepetroleum liquid 22 for collection (e.g. extracted through acollection pipe 26. In some embodiments, the gas 24 (Magnegas) produced though this process includes suspended carbon particles since at least one of the electrodes of the arc 18 is made from carbon and serves as the source for the charged carbon particles or nanoparticles that travel with the manufactured hydrogen andaromatic hydrocarbon gas 24 and are collected along with, for example, the hydrogen and aromatic hydrocarbon molecules, thereby changing the burning properties of the resultinggas 24, leading to a hotter flame. In this example, if thefeedstock 22 is oil (e.g. used oil) and the fluid/gas 24 collected includes any or all of the following: hydrogen, ethylene, ethane, methane, acetylene, and other combustible gases to a lesser extent, plus suspended charged carbon particles or nanoparticles that travel with these gases. - The resulting gas is fed into either one or both burning operations as shown in
FIG. 1 . Thegas 24 produced by the above operation, referred to as Magnegas 24, is introduced to the incineration process at any or all of three steps. - In the exemplary incineration system shown in
FIG. 1 ,waste 132 is staged before entry into the system in, for example, ahopper 130. Some amount of thewaste 132 is fed into a primary incinerator orkiln 140 through afeed mechanism 134, for example, through afeed screw 134. Within thekiln 140, a high temperature is generated in order to decompose and decontaminate thewaste 132. In some embodiments, the high temperature is generated through burning of thewaste 132 by injecting air from anair injection system 92. In some embodiments, the combustion is generated through burning of combination of thegas 24 and afuel 90 such as oil or natural gas. Such combustion produces relatively high temperatures, but for somewaste 132, higher temperatures are needed than those achieved using fuel oil or natural gas alone. For such, the introduction of theMagnegas 24 into theprimary incineration chamber 140 through afeed line 180, either separate, or in conjunction with another fuel such as oil or natural gas, produces a significantly higher temperature, providing better decontamination ofsuch waste 132, in particular, improved breakdown of pollutants such as dioxins. EitherMagnegas 24 alone or a combination ofMagnegas 24 and other fuels 90 (or ohmic heating) produces the high temperatures needed to decontaminate thewaste 132. In some embodiments, anagitator 142 agitates or rotates thekiln 140 to expose more of thewaste 132 to the high temperatures and effectively/thoroughly decontaminate all of thewaste 132 within the kiln. - For brevity purposes, the exit for solids from the
waste 132 is not shown, but it is anticipated that a dumping action or another screw device will remove residual solids (not shown) from thekiln 140, which, is later sorted and mined for metals, etc. - In some embodiments, exhaust gases from the kiln are directed into a
secondary burn chamber 150 through anexhaust mechanism 145. In some embodiments, theexhaust mechanism 145 is a simple length of insulated or uninsulated pipe, transferring exhaust gases into the secondary burn chamber. In some embodiments, theexhaust mechanism 145 treats and/or scrubs the exhaust gases by, for example, cooling the exhaust gases or filtering the exhaust gases. - In some embodiments, the exhaust gases are optionally cooled by a
chiller 143 and then mixed with the gas 24 (Magnegas) from agas 24feed line 182 before entering thesecondary burn chamber 150 where the exhaust gases and theMagnegas 24 are combusted. - In some embodiments, the exhaust gases are mixed with
Magnegas 24 from anothergas feed line 184 within thesecondary burn chamber 150. A secondary burn takes place in thesecondary chamber 150. The secondary burn further combusts and cleans the exhaust gases to reduce pollutants, in particular, reducing dioxin by breaking down the molecular bonds of dioxin. By usingMagnegas 24 in the secondary burn process, the resulting exhaust which travels out of the system through an exhaust device/chimney 152 is cleaner than if the exhausts from the initial burn we allowed into the atmosphere. - Note that, since the burning of the
waste 132, along with other fuels (e.g., oil, gas, and/or Magnegas 24) generatessignificant heat 141/151. It is fully anticipated that, in some embodiments, the excess heat is used to generate power 192 (e.g. electrical power 192) using, for example, asteam turbine 190 orfuel cell 190. - In summary, the
gas 24 produced within the arc 18 is used in any or all of the following incineration steps: thegas 24 is used in theprimary burning chamber 140 to increase the temperature at which thewaste 132 is burned; thegas 24 is mixed with flue gases from the primary incineration and, the mixed flue gases andMagnegas 24 is burned; and thegas 24 is used in the secondary burning chamber 50 to completely burn all exhaust fumes from the primary burning process. In all cases, it is anticipated that Magnegas is either used as a sole fuel to facilitate combustion, or Magnegas is used in conjunction with another fuel including, but not limited to, oil, propane, natural gas, synthetic natural gas, diesel, gasoline, etc., depending upon temperatures required and economic factors. - In some embodiments, the primary burn process in the
primary burn chamber 140, after initiation, continues through combustion of the materials being incinerated in theprimary burn chamber 140, without further injection of other fuels. In such, in some embodiments, thegas 24 is mixed with these flue gases from the primary incineration and, the mixed flue gases andMagnegas 24 is burned; and/or thegas 24 is injected into the secondary burning chamber 50 to completely burn all exhaust fumes from the primary burning process. - Equivalent elements can be substituted for the ones set forth above such that they perform in substantially the same manner in substantially the same way for achieving substantially the same result.
- It is believed that the system and method as described and many of its attendant advantages will be understood by the foregoing description. It is also believed that it will be apparent that various changes may be made in the form, construction and arrangement of the components thereof without departing from the scope and spirit of the invention or without sacrificing all of its material advantages. The form herein before described being merely exemplary and explanatory embodiment thereof. It is the intention of the following claims to encompass and include such changes.
