Abstract:
PURPOSE: A separator for solid oxide fuel cell is provided to prevent the loss due to the partial shortage of reaction gas by obtaining uniformity of flow, and to prevent the damage of a separator, because fluid flows in at state of high temperature by heat transfer. CONSTITUTION: A separator for solid oxide fuel cell comprises a separator(20,30). The separator is arranged at reaction side(11) of an upper part and a lower part, respectively. The separator guides the flow of fuel at upper side, and guides the flow of oxygen at lower side. Current collecting uniform-flow parts(21,31) are equipped in the separator in order to flow oxygen and fuel to each reaction side uniformly.

PURPOSE: A low-carbon lifting and melting furnace using plasma/gas combustion and fusion and a melting method and system using the same are provided to produce electronic frits as well as general glass by melting granule-type materials in a lifted state. CONSTITUTION: A low-carbon lifting and melting furnace(100) comprises a furnace body(110), a melting bath(120) formed inside the furnace body, a melting unit(130) which is formed on the upper side of the melting unit to melt raw materials, a raw material feeding unit(140) which is formed on the outer side of the melting unit, a plasma/gas melting device(150) which discharges mixed flame produced from plasma/gas, an exhaust pipe(160) which is formed on one side of the melting bath and discharges exhaust gas, and a tap hole(170) which discharges slag melt from the melting bath.

PURPOSE: A 3-way high-temperature valve is provided to prevent the curing promotion and early abrasion of a sealing gasket by changing a flow path by rotating a blade by 90°. CONSTITUTION: A 3-way high-temperature valve comprises a body(110), a first flow path(120), a second flow path(130), a third flow path(140) and a path changing unit(150). The body comprises a closed space. The first flow path is communicated with one side of the body, and high-temperature fluid flows into the first flow path. The fluid is discharged to the second flow path. The third flow path is communicated with one side of the body orthogonal to the second flow path and discharges the high-temperature fluid. The path changing unit is installed in the body and alternately opens/closes the second and third flow paths.
Abstract:
A device for gradually recycling cooling gas is provided to gradually fill and discharge cooling gas in a short time even if operation pressure in a cooling chamber is increased by forming plural pressure tanks. A device for gradually recycling cooling gas comprises a medium pressure tank(120), a low pressure tank(110), a high pressure tank(130), and a cooling chamber(200). The medium pressure tank, the low pressure tank, and the high pressure tank are gradually filled with cooling gas witch is conveyed to a recycling device(100) by opening a valve and engaged with first and second compressors and a vacuum pump(160). The cooling chamber gradually discharges the filled cooling gas to perform a cooling process. The tanks are repeatedly filled with the cooling gas witch is used for the cooling process by re-conveying the cooling gas to the recycling device.
Abstract:
A 3-way switching valve of a self regenerative burner is provided to install a packing member in an open/close wing of a rotation open/close member instead of an inner diameter of a through hole so that air for combustion or exhaust air smoothly flows. A 3-way switching valve includes a first body(110), a second body(120), and a rotation opening/closing device(130). The first body includes one single passage(111). The second body is coupled to the first body with a flange(115). The second body has two divided passages(122,123) by a dividing plate(121). The rotation opening/closing device is installed in the division plate in parallel. One of the two divided passages is selectively open/closed by coupling a packing member(134) to an outer circumference of a pair of wings(132).
