like gained by fermenting livestock manure, food waste, or the
like.

of a rotatable disk-shaped steam injector, which has a plurality of
nozzles mounted thereon, is applied to the disk-shaped steam
injector and then action energy of the injected steam which returns

to providing a small-scale combined heat and power generator
configured to easily generate electric energy using a small-scale
heat source gained from biogas, biomass, combustible waste
resources, and the like which are small-scale heat sources.
Technical Solution
[0005] One aspect of the present invention provides a small-scale
combined heat and power generator (10) including a steam
introduction pipe (102) into which steam is introduced; a
disk-shaped steam injector body (104) rotatably installed on an end
portion of the steam introduction pipe through a steam leakage
prevention bearing assembly (103); a steam injection nozzle (106)
mounted on an end portion of a steam injection path (105) connected
to an outer circumferential surface of the body; a steam injection
plate (107) mounted adjacent to the steam injection nozzle; a steam
reflection inducing groove (108) installed to reflect steam
injected onto the steam injection plate; a power generator (109)
configured to generate power; and a heat exchanger (110) configured
to produce hot water, wherein since reaction energy of a steam
injection force from the nozzles (106) of a disk-shaped steam
injector, which has a plurality of nozzles mounted thereon, is
applied to the disk-shaped steam injector and then action energy of
the injected steam which returns by performing a U-turn after

steam injection plate (107) adjacent thereto installed to reflect
the injected steam is also applied to the disk-shaped steam
injector, a rotational force of the steam injector is doubled in a
power generating system without a separate turbine.
[0006] High pressure steam introduced into the rotating steam
injector through the steam leakage prevention bearing assembly
(103) may be prevented from leaking from a rotary shaft of the
steam injector so that power generating efficiency of the steam
injector may be maximized.
[0007] Since a diameter of the steam injection path (105) is large,
and a diameter of each of the steam injection nozzles (106) is
small, a flow velocity may increase according to fluid mechanics,
and thus the steam injection force may increase.
[0008] The path (105) may be elongated to be connected to the steam
injector body (104) and a diameter of the disk-shaped steam
injector may increase to secure the rotational force on the basis
of a principle of a lever.

plural according to a generated amount of the steam to double the
rotational force of the steam injector.
[0010] The steam injection path may be circularly streamlined and
have the nozzle mounted on an end portion thereof to reduce air
resistance and reduce loss of the rotational force so that the
rotational force of the steam injector may be secured.
Advantageous Effects

because electric energy is produced using small-scale steam from
the small-scale heat source simply and effectively.
[0013] Further, the small-scale combined heat and power generator
using the steam injector of the present invention has a
small-scale, and can be movably installed in all areas having a
small-scale heat source such as biogas, biomass, waste
incineration, and the like in each region including such areas, and
thus electric energy can be produced in addition to protecting
Earth's environment.
[0014] In addition, since the small-scale combined heat and power
generator using the steam injector of the present invention does
not have a separate power generating turbine to gain the rotational
force, production costs are low, a structure is simple, and thus
maintenance is convenient.

MODES OF THE INVENTION
[0021] Hereinafter, the preceding exemplary embodiments will be
described in detail with reference to the accompanying
drawings.
[0022] FIG. 1 is a perspective view illustrating a configuration of
a small-scale combined heat and power generator using a steam
injector according to an embodiment of the present invention, and
FIG. 2 is an enlarged view of a main portion illustrating a steam
injection plate 107 of the small-scale combined heat and power
generator using the steam injector, and a direction of steam which
is reflected after colliding with steam reflection inducing grooves
108 installed so that the injected steam is reflected after
colliding with the steam reflection inducing grooves 108. FIG. 3 is
a cross-sectional view and an enlarged view of a main portion of a
steam leakage prevention bearing assembly of the steam injector.
FIG. 4 is a front view illustrating another embodiment of the
present invention in which at least one steam injector is
horizontally installed in plural according to a generated amount of
steam. FIG. 5 is a cross-sectional view illustrating that a steam
injection path is streamlined to reduce air resistance of the
rotating steam injector.
[0023] The small-scale combined heat and power generator using the
steam injector according to the present invention uses steam
generated from a small-scale heat source which may not use a
turbine due to a small scale thereof, and thus is implemented so
that since reaction energy of a steam injection force from nozzles
106 of a disk-shaped steam injector, which has a plurality of steam
injection nozzles mounted thereon, is applied to the disk-shaped
steam injector and then action energy of the injected steam which
returns by performing a U-turn after colliding with the steam
reflection inducing grooves 108 of the steam injection plate 107
adjacent thereto is also applied to the disk-shaped steam injector,
a rotational force of the steam injector is doubled without a
turbine.
[0024] First, according to the embodiment of the present invention,
the small-scale combined heat and power generator 10 shown in FIG.
1 includes a steam introduction pipe 102 into which steam is
introduced, a disk-shaped steam injector body 104 rotatably
installed on an end portion of the steam introduction pipe through
a steam leakage prevention bearing assembly 103, the steam
injection nozzles 106, which are each mounted on end portions of
steam injection paths 105 connected to an outer circumferential
surface of the body, the steam injection plate 107 mounted adjacent
to the steam injection nozzles, the steam reflection inducing
grooves 108 installed to reflect steam to the steam injection
plate, a power generator 109 configured to generate power, a heat
exchanger 110 configured to produce hot water, and the like.
[0025] High pressure steam introduced into the rotating steam
injector through the steam leakage prevention bearing assembly 103
is prevented from leaking from a bearing of a rotary shaft so that
power generating efficiency of the steam injector is maximized.
[0026] The steam injection nozzles 106 and the steam injection
plate 107 of the steam injector are installed adjacent to each
other, and the steam injected from the nozzles performs a U-turn so
that the rotational force of the steam injector is maximized.
[0027] Since a diameter of each of the steam injection paths 105 is
large, and a diameter of each of the steam injection nozzles 106 is
small, flow velocity may increase according to fluid mechanics, and
thus the steam injection force may also increase.
[0028] The paths 105 may be elongated to be connected to the steam
injector body 104 and a diameter of the disk-shaped steam injector
may increase to secure the rotational force on the basis of a
principle of a lever.
[0029] Further, at least one steam injector body 104 may be
horizontally installed in plural according to a generated amount of
the steam to double the rotational force of the steam injector.
[0030] In addition, the steam injection path is circularly
streamlined and has the nozzle mounted on an end portion thereof to
reduce air resistance and reduce loss of the rotational force so
that the rotational force of the steam injector is secured.
[0031] To this end, the steam injector includes the steam injector
body 104 rotatably installed on an end portion of the steam
introduction pipe 102 and in which the high pressure steam is
supplied to the paths through the steam leakage prevention bearing
103, the plurality of steam injection paths 105 installed on an
outer circumferential surface of the body 104 and linked therewith,
and the plurality of steam injection nozzles 106 configured to
inject the high pressure steam.
[0032] In this case, the paths and the nozzles installed on the
outer circumferential surface of the steam injector body 104 may
each be designed to have the number thereof, directions, and sizes
to be variously changeable, and accordingly, a direction, a water
amount, water pressure, and the like of the injected steam may be
adjusted.
[0033] Further, since the nozzles provided on the steam injector
may include the steam injection nozzles 106, and when being
horizontal and parallel to the steam injector, the steam injection
nozzles 106 may rotate at high speed due to a reaction force
against an action force maximally applied thereto, a steam
injection angle may be adjusted to adjust a rotational speed of the
steam injector.
[0034] Accordingly, the bearing 103 of the rotary shaft of the
steam injector is a part from which steam leakage occurs, and since
whether the high pressure steam leaks or not is directly related to
energy efficiency, a mounted steel plate shield may come into
contact with a steam leakage prevention ring to be rotated due to a
steam pressure when the steam injector is driven, and thus each of
the steel plate shield and the steam leakage prevention ring 103f
are configured to have a structure in which the steam is
efficiently prevented from leaking at a minimum friction
resistance, and thus the steam injector is efficiently rotated.
[0035] Further, the power generator 109 is installed to be directly
connected to the steam injector, and has a structure to produce
electric energy according to rotation of the steam injector.
[0036] In addition, the steam injector may be designed to have the
number of steam injectors to be installed, a diameter thereof, and
the like to be variously changeable according to a use environment
thereof.
[0037] The enlarged view of the steam reflection inducing grooves
shown in FIG. 2 shows a form in which the steam is injected to the
adjacent steam injection plate 107 by the nozzles 106, and
reflected after colliding with the steam reflection inducing
grooves 108 installed on the steam injection plate. It is
configured so that both the reaction energy according to steam
injection and the action energy according to reflection of the
injected steam may be applied to the disk-shaped steam injector to
maximize the rotational force.
[0038] In the cross-sectional view and the enlarged view of the
main portion of the steam leakage prevention bearing assembly of
the steam injector shown in FIG. 3, since the steam leakage from
the steam injector is directly related to the energy efficiency,
and thus the mounted steel plate shield 103e may come into contact
with the steam leakage prevention ring 103f to be rotated due to
the steam pressure when the steam injector is driven, each of the
steel plate shield and the steam leakage prevention ring 103f form
a structure in which the steam is efficiently prevented from
leaking at the minimum friction resistance, and is installed in
plural so that the power generating efficiency of the steam
injector is maximized.
[0039] As another embodiment of the present invention, the
small-scale combined heat and power generator shown in FIG. 4 has
at least one steam injector, horizontally installed therein in
plural according to an amount of supplied steam, in order to be
capable of further improving power generating performance of the
small-scale combined heat and power generator.
[0040] Meanwhile, the steam injector shown in FIG. 5 is implemented
to circularly streamline the steam injection paths 105 and mount
the nozzles on the end portion thereof so that the air resistance
may be reduced to reduce the rotational force. Further, the
above-described action of the present invention will be described
below.
[0041] First, the small-scale combined heat and power generator
according to the present invention introduces the high pressure
steam from the steam introduction pipe 102 to the steam injector
body 104 through the disk-shaped steam injector, on which the
nozzles configured to inject the steam are mounted, to rotate the
power generator without an impulse steam turbine which requires the
mass high pressure steam.
[0042] Accordingly, the high pressure steam introduced into the
steam injector body produces electric energy without the turbine
because both the reaction energy of the steam injection force which
is intensively injected from the steam injection nozzles 106
through the steam injection paths 105, and the action energy of the
steam injection force which returns after colliding with the steam
reflection inducing grooves rotates the steam injector configured
to inject the steam.
[0043] Accordingly, the small-scale combined heat and power
generator according to the present invention may generate power by
producing steam in all areas, each having the small-scale heat
source, and since a small-scale heat source which may not generate
power with a general impulse turbine power generator may be easily
used, environmentally-friendly and convenient power generation may
be performed.
[0044] Meanwhile, the present invention is not limited to the
above-described embodiments and may be variously modified and
adjusted by those skilled in the art without departing from the
spirit of the present invention.
[0045] Accordingly, the appended claims of the present invention
include all modifications of the present invention within the scope
of the present invention.
