Abstract: The present disclosure provides a combined reformer capable of continuously performing different reforming reactions by sequentially supplying heat from the combustion gas to the two or more catalyst tubes that react at different temperatures. Also, the present disclosure provides a combined reformer capable of enhancing the reforming efficiency with a U-shaped first catalyst tube including a preheating section where the hydrocarbon gas is preheated, flowing parallel to the combustion gas, and a reforming section where the catalytic reforming takes place.

Abstract: Disclosed herein is a turbine blade having a leading edge, a trailing edge, a pressure side, and a suction side and having a cooling passage formed therein. The turbine blade includes a plurality of cooling holes formed on the pressure side or the suction side. Each of the cooling holes includes, a through-hole having a circular cross-section and angled outwardly toward the pressure side or the suction side from the cooling passage, a circular sink formed concavely with respect to the pressure side or the suction side in the vicinity of an upstream side of an exit of the through-hole, and an elliptical sink formed concavely with respect to the pressure side or the suction side in the vicinity of a downstream side of the exit of the through-hole.

Abstract: An exhaust gas flow regulator and a heat recovery steam generator including the same are provided. The exhaust gas flow regulator includes a plurality of first tubes spaced apart from each other in a vertical direction, a support plate disposed in a direction perpendicular to the extension direction of the first tubes and through which the plurality of first tubes penetrates, and a second tube disposed at one or both ends of the support plate so as to be coupled to the support plate and extending parallel to the first tubes, wherein the second tube is provided with a guide plate disposed to redirect exhaust gases flowing adjacent to the second tube toward the first tube.
