Description
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Moreover, as a number of the air suction and exhaust openings increases, a risk of leakage of the exhaust gas to outside increases.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
