Description
TECHNICAL FIELD
[0001] The present invention relates to a boiler system using a
fuel cell. More particularly, the present invention relates to a
fuel cell based boiler system in which, in a structure of the fuel
cell, an exhaust opening which discharges exhaust gas generated
during operation of a boiler and an air suction opening which
supplies oxygen required for operation of the boiler are configured
for efficiency.
BACKGROUND ART
[0002] In countries having four distinct seasons or in cold
countries, a boiler system, which uses kerosene, gas, coal or the
like as an energy source for heating a room of a home or a
building, is used.
[0003] A general boiler system has a boiler installed indoors or
outdoors for receiving and burning fuel. Water is heated by heat of
combustion in the boiler, and the water heated thus is circulated
through a heat dissipation circulating line connected to the boiler
buried in a floor of the room. While the water repeats the
circulation in which the water is heated at the boiler, circulates
through the heat dissipation circulating line, and heated at the
boiler again, the heat is transmitted to, and heats, the room
floor.
[0004] And, a warm water line is connected between the boiler and
city water line which supplies city water and is connected to a
washroom, a laundry room, a kitchen, and so on.
[0005] However, when the boiler system heats the water with the
heat of combustion of the gas or kerosene for heating the room and
using the warm water, it consumes a large amount of gas or
kerosene, which not only causes emission of pollutants that are
severely harmful to human bodies, but also increases an economic
burden to households and the fossil fuel is gradually being
exhausted.
[0006] Recently, in order to solve such a problem, a scheme has
been under research in which a fuel cell is installed in a house or
a building for producing and using electricity and heat a user
requires personally to reduce emission of the pollutants and rates
of electricity and room heating while generating the electricity
and the heat at the same time.
[0007] However, since the electricity produced from the fuel cell
is supplied to outside and the heat incidentally generated is
recovered in a mode of the warm water and is used for the room
heating and warm water supply, the boiler is used together with the
fuel cell.
[0008] According to this, air suction and exhaust openings for the
fuel cell and air suction and exhaust openings for the boiler are
respectively required, resulting in inconvenience in view of space
and installation.
[0009] Moreover, as a number of the air suction and exhaust
openings increases, a risk of leakage of the exhaust gas to outside
increases.
DISCLOSURE
Technical Problem
[0010] The present invention has been made in an effort to provide
a boiler system using a fuel cell having advantages of resolving
inconveniences in view of space, structure, and installation
occurring for mounting air suction and exhaust openings for a fuel
cell and air suction and exhaust openings for a boiler, and
reducing risk of exhaust gas leakage caused by an increased number
of the air suction and exhaust openings.
[0011] Accordingly, an object of the present invention devised for
solving the problems is to provide a boiler system using a fuel
cell, which may resolve inconveniences in view of space, structure,
and installation occurring for mounting air suction and exhaust
openings for a fuel cell and air suction and exhaust openings for a
boiler, and may reduce risk of exhaust gas leakage caused by an
increased number of the air suction and exhaust openings.
Technical Solution
[0012] To achieve the object of the present invention, a boiler
system using a fuel cell includes a boiler installed in a home, a
building, or the like, a fuel cell for generating electricity and
reaction heat by electrochemical reaction between a fuel and
oxygen, a storage tank for recovering and storing the reaction heat
generated by the fuel cell with a fluid, a room heating line buried
beneath a room floor of the home, the building, or the like, a warm
water line connected to supply warm water to a washroom or a
kitchen of the home or the building through the boiler or the
storage tank when water is supplied thereto from the outside, and a
suction and exhaust integrated pipe having at least two of at least
one first exhaust line, at least one first suction line of the
boiler, at least one second exhaust line, and at least one second
suction line of the fuel cell connected thereto to be used in
common.
Advantageous Effects
[0013] The boiler system using a fuel cell in accordance with the
present invention may resolve inconveniences in view of space,
structure, and installation of the boiler system, such as a spatial
restriction occurring for mounting the first exhaust line, the
first suction line of the boiler, the second exhaust line, and the
second suction line of the fuel cell, as an example, problems of
making a plurality of holes in inner and outer walls of the boiler
room.
[0014] Since the suction lines and the exhaust lines of the boiler
and the fuel cell may be fabricated as a single suction and exhaust
integrated pipe having a multiple pipe member or a partition wall,
a complex pipe configuration may be simplified and leakage from the
pipes may be reduced.
[0015] The damper means or the electronic valve means provided to a
crossing point of suction and exhaust lines of the boiler and the
fuel cell may prevent a reverse flow in view of structure.

and the second exhaust line 139 and the second suction line 135 of
the fuel cell 130, may be made to be in communication with the
atmosphere through a suction and exhaust integrated opening 190a
via the suction and exhaust integrated pipe 190.
[0033] According to this, inconveniences in view of space,

spatial restriction occurring for mounting the first exhaust line
117 and the first suction line 118 of the boiler 110, and the
second exhaust line 139 and the second suction line 135 of the fuel
cell 130, as an example, problems of making a plurality of holes in
inner and outer walls of the boiler room may be resolved.
[0034] The suction and exhaust integrated pipe 190 in the boiler
system 100 using a fuel cell in accordance with a preferred
embodiment of the present invention will be described with
reference to FIGS. 2A to 2C.

[0036] Referring to FIG. 2 to FIG. 4, the suction and exhaust
integrated pipe 190 in the boiler system 100 using a fuel cell in
accordance with a preferred embodiment of the present invention may
be constructed as a quadruple pipe in which a first pipe member
191, a second pipe member 192, a third pipe member 193, and a
fourth pipe member 194 are arranged to be overlapped and centered
on a concentric axis respectively connected to the first exhaust
line 117 and the first suction line 118 of the boiler 110, and the
second exhaust line 139 and the second suction line 135 of the fuel
cell 130.
[0037] The suction and exhaust integrated pipe 190 in the boiler
system 100 using a fuel cell in accordance with a preferred

on a concentric axis.
[0038] Further, as shown in FIG. 3, the second suction line 135 and
the second exhaust line 139 of the fuel cell 130 may be arranged in
a mode of branches within the first pipe member 191.
[0039] The second suction line 135 and the second exhaust line 139
of the fuel cell 130 may be respectively connected to the first
pipe member 191 and the second pipe member 192 which are
respectively connected to the first exhaust line 117 and the first

suction area A of the boiler 110 and the fuel cell 130 and an
exhaust area B of the boiler 110 and the fuel cell 130 according to
an exhaust rate and a suction rate.
[0041] Accordingly, since the suction lines and the exhaust lines
of the boiler 110 and the fuel cell 130 may be fabricated as the
single suction and exhaust integrated pipe 190, a complex pipe
configuration may be simplified and leakage from the pipes may be
reduced.
[0042] Referring to FIGS. 5 to 13, variations of the boiler system
using a fuel cell in accordance with the preferred embodiment of
the present invention will be described.

190 in the boiler system 100 using a fuel cell in accordance with a
preferred embodiment of the present invention may have a first pipe
member 191 connected to a suction and exhaust integrated opening
190a partitioned with a partition wall 191a for introducing outdoor
air introduced thereto to the first suction line 118 of the boiler
110 and the second suction line 135 of the fuel cell 130, and
discharging gas being discharged through the first exhaust line 117
and the second exhaust line 139 of the fuel cell 130 through the
integrated pipe opening 190a via the first pipe member 191.
[0045] That is, the suction openings and the exhaust openings of
the boiler 110 and the fuel cell 130 are integrated into one to use
the same in common.
[0046] As shown in FIG. 6, a suction integrated pipe 191 in the
boiler system 100 using a fuel cell in accordance with a preferred
embodiment of the present invention may be configured such that the
suction integrated pipe 191 introduces outdoor air introduced
thereto through a first pipe member 191 connected to one suction
integrated opening 190a to the first suction line 118 of the boiler
110 and the second suction line 135 of the fuel cell 130, and may
allow exhaust gas being discharged through the first exhaust line
117 and the second exhaust line 139 of the fuel cell 130 through
another first pipe member 191 via another suction and exhaust
integrated opening 191a.
[0047] That is, suction openings and exhaust openings of the boiler
110 and the fuel cell 130 may be used in common, respectively.
[0048] In this case, as shown in FIG. 7, in order to prevent a
reverse flow from taking place by controlling a suction flow
between the first suction line 118 of the boiler 110 and the second
suction line 135 of the fuel cell 130 and an exhaust flow between
the first exhaust line 117 of the boiler 110 and the second exhaust
line 139 of the fuel cell 130, which use the first pipe member 191

preferred embodiment of the present invention may be a double pipe
connected to a suction and exhaust integrated opening 190a.
[0050] The double pipe has a first pipe member 191 having the first
exhaust line 117 of the boiler 110 and the second exhaust line 135
of the fuel cell 130 made to be in communication therewith such

191 as an exhaust line in common, and a second pipe member 192
around the first pipe member 191 partitioned with a partition wall
192a having the first suction line 118 of the boiler 110 and the
second suction line 139 of the fuel cell 130 made to be in
communication therewith such that suction gases of the first
suction line 118 of the boiler 110 and the second suction line 139
of the fuel cell 130 are prevented from mixing for maintaining
respective characteristics of the suction gases.
[0051] In this case, as shown in FIG. 9, in order to prevent a
reverse flow from taking place by controlling an exhaust flow
between the first exhaust line 117 of the boiler 110 and the second
exhaust line 139 of the fuel cell 130, which use the first pipe
member 191 in common, damper means or electronic control means 160,
such as a solenoid valve or the like, may be used at a crossing
point of the two lines.
[0052] Further, as shown in FIG. 10, the suction and exhaust
integrated pipe 190 in the boiler system 100 using a fuel cell in
accordance with a preferred embodiment of the present invention may
be a double pipe connected to a suction and exhaust integrated
opening 190a having partition walls formed at inner and outer pipe
members.
[0053] Since the double pipe has the first pipe member 191
partitioned with the partition wall 191a with the first exhaust
line 117 of the boiler 110 and the second exhaust line 139 of the
fuel cell 130 made to be in communication therewith such that the
boiler 110 and the fuel cell 130 use the first pipe member 191 as
an exhaust line in common by dividing an area of the first pipe
member 191, preventing exhaust gases of the first exhaust line 117
of the boiler 110 and the second exhaust line 139 of the fuel cell
130 from mixing, characteristics of the exhaust gases may be
maintained.
[0054] Also, by partitioning the second pipe member 192 around the
first pipe member 191 with the partition wall 192a and making the
first suction line 118 of the boiler 110 and the second suction
line 135 of the fuel cell 130 to be in communication therewith,
preventing the suction gases of the first suction line 118 of the
boiler 110 and the second suction line 135 of the fuel cell 130
from mixing, characteristics of the suction gases may be
maintained.
[0055] As shown in FIG. 11, the suction and exhaust integrated pipe
190 in the boiler system 100 using a fuel cell in accordance with a
preferred embodiment of the present invention may be a triple pipe
connected to a suction and exhaust integrated opening 190a.
[0056] The triple pipe may have the first pipe member 191 to be in
communication with the first exhaust line 118 of the boiler 110 and
the second exhaust line 135 of the fuel cell 130 such that the
boiler 110 and the fuel cell 130 use the first pipe member 191 as
an exhaust line in common, and the second pipe member 192 and the
third pipe member 193 which surround the first pipe member 191 in
succession to be in communication with the second suction line 139
of the fuel cell 130 and the first suction line 117 of the boiler
110 respectively, preventing suction gases of the first suction
line 117 of the boiler 110 and the second suction line 139 of the
fuel cell 130 from mixing, thereby enabling to maintain
characteristics of the suction gases, respectively.
[0057] In this case, as shown in FIG. 12, though it has a triple
pipe structure, by partitioning the first pipe member 191 with the
partition wall 191a into two areas, and making the first exhaust
line 118 of the boiler 110 and the second exhaust line 135 of the
fuel cell 130 to be in communication therewith such that the boiler
110 and the fuel cell 130 use the first pipe member 191 as an
exhaust line in common by dividing an area of the first pipe member
191, preventing the exhaust gases of the first exhaust line 118 of
the boiler 110 and the second exhaust line 135 of the fuel cell 130
from mixing, characteristics of the exhaust gases may be
maintained, respectively.
[0058] In this case, as shown in FIG. 13, in order to prevent a
reverse flow from taking place by controlling an exhaust flow
between the first exhaust line 118 of the boiler 110 and the second
exhaust line 135 of the fuel cell 130 which use the first pipe
member 191 in common, a damper means or electronic control means
160, such as solenoid valve, may be used at a crossing point of the
two lines.
