| 摘要 |
The present invention relates to a steam production apparatus using exhaust gas from a fuel cell, wherein the steam production apparatus produces hot water and steam by using the exhaust gas discharged from a fuel cell power generation system which produces electricity using the fuel cell, followed by supplying the hot water and the steam to an area of demand. Accordingly, the steam production apparatus can enhance the thermal efficiency of a fuel cell system and prevent environmental pollution caused by high-temperature exhaust gas. According to the present invention, the steam production apparatus using the exhaust gas from the fuel cell comprises a fuel cell system which produces electricity by using hydrogen obtained by modifying fossil fuel including LNG, and discharges exhaust gas of a certain temperature or higher generated in a modification process of the fossil fuel, through an exhaust pipe; an economizer installed in the exhaust pipe, and converting water supplied from an outdoor water tank into hot water by heat exchange with the exhaust gas; a steam tank to which a hot water pipe and a steam pipe are respectively connected in order to supply hot water to an area of demand and in order to supply steam to an area of demand, wherein the hot water produced in the economizer is temporarily stored in the steam tank; and an evaporator installed between the economizer and the fuel cell system, and converting the hot water which is supplied from the steam tank by heat exchange with the exhaust gas into steam, followed by resupplying the steam to the steam tank. |
