Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an oxidizer, in particular
to an oxidizer of burner that renders a preferable burning
efficiency and decreases the discharging of burnt contaminants and
pollutants.
[0003] 2. Description of the Related Art
[0004] Burners such as boilers and incinerators are generally used
in industry to generate energy and eliminate wastes. The steam and
hot water produced by burning could apply in generating electric
power, steam/electricity cogeneration, industrial procedure,
heating system, and so on. Recently, as the fuel price is soaring
high and the global warming and environmental deterioration become
a general intensive concern, the aspect upon fuel economy, i.e.
enhanced burning efficiency, low pollutant, and contaminating
emissions, becomes an important timely issue.
[0005] Comprehensibly, a substance, especially for a solid one, is
always burnt from its surface toward the interior when the heating
temperature progressively increases. However, the deficiency
attendant on such typical burning is to induce a slow and
incomplete combustion reaction in virtue of the lack of sufficient
oxygen among the interiority and failing to contact the exterior
oxygen, which results in decreasing combustion efficiency and
releasing contaminants to considerably pollute the environment.
[0006] Referring to FIG. 1, the general operation of the
incinerator 1 burning wastes 2 (for instance of trash), the wastes
2 are placed within the incinerator 1. The burning would not start
until a sufficient collection of the wastes 2 attains. Whereby, the
accumulation of the wastes 2 is tight in the sense that merely the
top surface thereof could contact external oxygen, except for
others below the surface level. Hence, the pyrolysis only reacts on
the top surface of the wastes 2 to perform burning, and the
interior of the wastes 2 becomes arduous to be burnt as a result of
the lack of high temperature and enough oxygen. In this manner, the
burning is incomplete due to that the wastes 2 are not exhaustively
burnt away, and pollutant air such as carbon monoxide, unburnt
hydrocarbon (UHC), and soot is hence generated.
[0007] In consideration of promoting the burning completion and
speed, a combustion promoter 3 such as fuel oil or solid refuse
derived fuel (RDF) is generally added into the wastes 2 during
burning. However, although the promoter 3 could infiltrate the
tight-heap wastes 2, promote the burning speed, and raise the
temperature, its tight accumulation still makes the interior or
bottom of wastes 2 incapable of directly contacting the exterior
oxygen. Therefore, the burning still starts from the top surface
and propagates sluggishly or difficultly toward the interior. The
problems of a slow burning speed, a poor efficiency, and an
incomplete combustion are still manifested.
SUMMARY OF THE INVENTION
[0008] The object of the present invention is to provide an
oxidizer of burner possessed of high oxidization that facilitates
to increase the burning speed and burns waste far more completely,
so as to enhance the efficiency and decrease the producing of
pollutants from burning.
[0009] The oxidizer of burner in accordance with the present
invention mainly provides a burner or a combustion chamber with an
oxidizer. Wherein, the oxidizer is a liquid compound consisting of
a hydrogen peroxide (H.sub.2O.sub.2) and a dihydrogen monoxide
(H.sub.2O, water). Herein the oxidizer is mixed in the proportion
of a range of 30.about.100% H.sub.2O.sub.2 to a range of
0.about.70% H.sub.2O. Whereby, the oxidizer sprayed on wastes is
heated and transformed into heating steam and gaseous oxygen by
burning the wastes within the combustion chamber. As a result, the
high oxidization of the oxidizer speeds up burning and promotes
burning efficiency as well as complete combustion. Therefore, the
generations of carbon monoxide, unburnt hydrocarbon (UHC) and
particulates deemed as pollutants are preferably decreased.
[0010] The advantages of the present invention over the known prior
arts will become more apparent to those of ordinary skilled in the
art by reading the following descriptions with relating
drawings.

invention;
[0012] FIG. 2A and 2B are schematic views showing the first
preferred embodiment of the present invention; and
[0013] FIG. 3 shows the photo for an experiment illustration of the
present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] Before describing in greater details, it should note that
the like elements are denoted by the similar reference numerals
throughout the disclosure.
[0015] Referring to FIG. 2 showing the present invention, a burner
4 includes a combustion chamber 41 for receiving wastes 5 on which
an oxidizer 6 could be scattered. Wherein, the burner 4, such as a
fire tray, an incinerator, or a boiler, mainly served to burn the
wastes 5 that could be directed to trash, the burner 4 herein is
directed to an incinerator 4.
[0016] Further, the oxidizer 6 is a liquid compound essentially
consisting of a hydrogen peroxide (H.sub.2O.sub.2) 61 and a
dihydrogen monoxide (H.sub.2O, water) 62. Wherein the
H.sub.2O.sub.2 61 is in the proportion of 30.about.100% (percent by
weight) and the H.sub.2O 62 is in the proportion of 0.about.70%
(percent by weight). Moreover, the oxidizer 6 could be directly
applied on the trash 5 before the burning, or alternatively be
sprayed on the surface of the trash 5 during the burning for
enhanced oxidizer decomposition. Herein the following descriptions
depict the addition of the oxidizer 6 on the surface of the trash 5
before burning.
[0017] Further referring to FIG. 2, in order to avoid the
environmental pollution, the oxidizer 6 is previously blent
according to afore proportions of elements as well as the property
of the trash 5 to be burnt. Then, before placing the trash 5 in the
incinerator 4, the liquid oxidizer 6 is sprayed on the surface of
the trash 5. Herein, the liquid oxidizer 6 can readily infiltrate
into the interior or bottom trash 5. After placing the trash 5 in
the incinerator 4, a firing (i.e. by external means, not shown)
used to be arranged within the incinerator 4 serves to ignite and
burn the top surface of the trash 5 and drastically enhance
decomposition of the oxidizer 6 into gaseous oxygen 611 and heating
steam 621 with significant heat release under the high temperature
inside the chamber 41. Accordingly, not only the top surface of
trash 5 but also the interior and bottom trash 5 along with the
firing could attain a favorable burning since the oxygen 611 can
abundantly spread among the trash 5. Wherein, the chemical reaction
formula showing the decomposition of the oxidizer 6 sets forth
below:
H.sub.2O.sub.2.fwdarw.H.sub.2O+1/2O.sub.2+98.2 kJ/mol
[0018] In practice, the hydrogen peroxide 61 is previously diluted
by water 62 to lower the concentration thereof for a safety concern
of overheat. Whereas, the hydrogen peroxide (H.sub.2O.sub.2) 61
essentially possesses the property of oxidization higher than those
of chlorine, chlorine dioxide, or potassium permanganate and would
further enhance such advantaged property subordinated to that of
fluorine in the periodic table of elements while the H.sub.2O.sub.2
61 is also decomposed into hydroxyl (OH--) in the flame of fuel
combustion or by the catalysis of the catalyst. In general, the
oxidizer 6 alone is decomposed to produce oxygen (O.sub.2) 611 and
water (H.sub.2O) 621. Such generation of the hydroxyl (OH--) in the
flame is accordingly proven by the sensitivity analysis of chemical
reactions that it is helpful to directly enhance the burning
velocity. Alternatively, if the hydrogen peroxide (H.sub.2O.sub.2)
61 associates with the firing made from hydrocarbon, the heated
hydrogen peroxide 61 becomes the supporter or oxidant for
decreasing the heating absorption of nitrogen and greatly raising
the burning temperature within the combustion chamber 41 as
compared to burning with air. As a result, the burning efficiency
of the firing along with the wastes 5 is evidently promoted by the
cooperation of the gaseous oxygen 611 and heating steam 621 as well
as significant amount of heat release and oxygenated combustion,
which respectively results from the heated oxidizer 6 in which the
hydrogen oxygen 61 decomposes into superheat and gaseous oxygen
611, and the water 62 vaporizes into heating steam 621.
[0019] Further, the oxidizer 6 of the present invention is put to
the following experiments:
Test 1 (For Application On Burning Wooden Shavings):
[0020] Two shares of wooden shavings at the same weight of 20 g are
provided on two discrete fire trays. One is sprayed by the oxidizer
relative to the previous specific proportion; the other is directly
burnt. The results and photos are shown as following table 1 and
FIG. 3:
TABLE-US-00001 TABLE 1 Burning subject Burning effect Wooden
shavings with oxidizer Firing in 2 seconds (A tray) without
redundancy Wooden shavings (B tray) Difficult to set them alight,
and need long burning time
[0021] The above results prove that the oxidizer indeed
significantly promotes the burning speed and complete combustion.
That is because, during burning, the wooden shavings with oxidizer
on A tray has sufficient oxygen fully disseminated therearound,
that is, to have the oxygen swiftly infiltrate from the top into
the interior of the shavings without being affected by the heaped
wooden shavings. Therefore, the burning speed is promoted and the
burning is far more complete, which entirely differentiates from
the simply and directly burning the wooden shavings of B tray that
inevitably incurs the occurrences of considerable smoke, air
pollution, and incomplete burning.
Test 2 (For Application On A boiler for Firing Wastes of Refuse
Derived Fuel, RDF):
[0022] The oxidizer is added during burning to render the swift
infiltration from the surface into the interior of the wastes by
the oxidizer's powerful oxidization as well as high conductivity of
the heating steam. Therefore, the burning efficiency is evidently
advanced to greatly improve the thermal exchange so as to average
the burning effect and reduce the release of carbon monoxide,
unburnt hydrocarbon (UHC), and other contaminants.
[0023] In addition, it is found that if to deem methane (CH.sub.4)
as a firing and to add different proportions of oxidizer into
wastes under the circumstances of the 1.0 equivalence ratio and
initial temperature at 150.degree. C., the experiments on the
adiabatic temperature and the laminar burning velocity would
present as follows:
TABLE-US-00002 TABLE 2 Adiabatic Laminar Burning Oxidizer
Temperature (k) Velocity (m/s) air 2286 0.71 100% O.sub.2 3065 4.80
100% H.sub.2O.sub.2 2811 4.62 100% (H.sub.2O + O.sub.2) 2458 1.20
50% H.sub.2O.sub.2 + 50% H.sub.2O 2450 2.22
[0024] The results from table 2 present that while the proportions
of the H.sub.2O.sub.2 and H.sub.2O are respective 50%, the burning
speed of the wastes is faster approximately at three times than
that of air.
[0025] For whatever application of the oxidizer on burners, they
substantially need to add the oxidizer into wastes, for the heated
oxidizer would be decomposed and transformed into gaseous oxygen
and heating steam to scatter among the interiors of the wastes or
the firings. Wherein, the gaseous oxygen urges burning, and the
heating steam advances convection temperature of burning. By means
of the sufficient oxygen as well as adequate temperature, the
burning reaction would swiftly get into the interior and bottom
wastes as well as the solid firing, rendering a far more complete
burning and higher burning efficiency. Accordingly, not only the
burning time shortens but also the problem of releasing carbon
monoxide, unburnt hydrocarbon, and other pollutants is reduced.
[0026] Furthermore, besides being diluted with water to decrease
the concentration, the hydrogen peroxide of the present oxidizer
could additionally associates with a stabilizer to control the
stability thereof and prevent from the risk of high activity.
Wherein, the stabilizer could be phosphate, stannate, nitrate, or
other appropriate elements whose ion concentration is below
10.sup.-2. Whereby, the addition of the stabilizer increases the
using safety, and the stabilized oxidizer would be readily stored
or delivered because its high activity becomes stable.
[0027] Thus, the present invention has the following improvements:
[0028] 1. The high oxidization of the heating hydrogen peroxide
promotes the burning reaction of the wastes to speed up the burning
by the swift infiltration from the top surface into the interior of
wastes. Thus, the sufficient oxygen spreading among the wastes
facilitates to average the burning effect (burning far more
completely) and decrease the generations of carbon monoxide,
unburnt hydrocarbon (UHC) and noxious contaminants. [0029] 2. The
ingredients of the oxidizer are low toxicant for human body, so no
instant dangers would occur. Wherein, the vapor pressure of the
hydrogen peroxide is merely about 300 Pa at the room temperature,
so that the property of the hydrogen peroxide for uneasily
evaporating substantially coincides with the request of safety
protection. Besides, the addition of the stabilizer can further
increase the using safety. [0030] 3. Although the hydrogen peroxide
of high concentration would decrease its decomposing speed by
dilution, the diluted hydrogen peroxide thereof would be more
stable for handling. Moreover, it may concern that the hydrogen
peroxide would restrain the development of microorganism in water.
However, in fact, the hydrogen peroxide composed of hydrogen and
oxygen would not accumulate within organism and not severely harm
the organism.
[0031] To sum up, the present invention takes advantages of an
oxidizer possessing heating steam with high conductivity and
powerful oxidization under the circumstance of heating. Thus, the
burning speed of wastes within a burner would be promoted by means
of the addition of the oxidizer, so as to advance the burning
efficiency and attain a more complete burning effect. Accordingly,
the release of carbon monoxide and unburnt hydrocarbon is reduced
to decrease damages to environment.
[0032] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
