The present disclosure relates to a flue gas exhaust system for an industrial furnace, especially a steam reforming furnace. The flue gas exhaust system comprises a stack having an inlet opening for introducing flue gas into the stack and an outlet opening for exhausting flue gas. The inlet opening of the stack is in fluid connection to an outlet of a heat recovery system of the industrial furnace. Further, the fluid connection between said heat recovery system outlet and said stack inlet opening comprises a transition flue gas duct that at least partly embraces a part of the stack.

A device with a steam generation function comprises a water storage cavity, a heating cavity with a steam outlet, a guide channel for communicating the water storage cavity with the heating cavity, and a heating element configured in the heating cavity, wherein the heating cavity has a first chamber and a second chamber communicated with the first chamber, and the first chamber is located on one side of the second chamber; and the heating element is configured in the first chamber, and the steam outlet is formed in the second chamber and is spaced from the first chamber in the horizontal direction by a preset first distance to prevent boiling water in the first chamber from being ejected via the steam outlet. The device provided by the present invention is safe in use.

A neutron absorbing insert for use in a fuel rack. In one aspect, the insert includes: a plate structure having a first wall and a second wall that is non-coplanar to the first wall; the first and second walls being formed by a single panel of a metal matrix composite having neutron absorbing particulate reinforcement that is bent into the non-coplanar arrangement along a crease; and a plurality of spaced-apart holes formed into the single panel along the crease prior to bending.

The present disclosure relates to an exhaust gas cooling device and method, and more particularly, to a device and method for installing an exhaust gas cooling device on the upper end of a duct of a heat recovery steam generator to cheaply cool the exhaust gas without occupying an additional dedicated area.

An object of the present disclosure is to reduce the costs using a cheap cooling device in the cooling path for cooling the exhaust gas.

In one aspect, the exhaust gas cooling device includes an exhaust gas cooling unit located on the upper end of a duct of a heat recovery steam generator connected with a gas turbine and for cooling the exhaust gas discharged from the gas turbine; and a control unit for controlling the exhaust gas cooling unit to lower the increase rate of the energy of the exhaust gas flowed into the heat recovery steam generator through the duct.

The present invention relates to a connecting apparatus for a steam generator disposed between a steam generator and a flow mixing header to fasten the steam generator to the flow mixing header in a sealed manner, and an integral reactor including the same. The connecting apparatus for a steam generator disposed between a steam generator and a flow mixing header and fastening the steam generator to the flow mixing header in a sealing manner includes: a baseplate mounted on the flow mixing header and having a through hole formed at the center thereof; and a steam generator connecting portion protruding along the circumference of the through hole in the base plate and allowing an outlet of the steam generator to be inserted and fastened thereto. Through this configuration, since the connecting apparatus for a steam generator is tightly fastened to the flow mixing header, leakage of a coolant therebetween may be prevented, and since the steam generator is horizontally disposed in the flow mixing header, structural stabilization may be achieved.

A tabletop steam sterilizer system is housed within a tabletop cabinet housing having a water inlet that is adapted for connection to a municipal water supply, thus allowing its use anywhere that there is a standard water supply and without need of a distilled water supply. The tabletop steam sterilizer system includes a plurality of independently operable sterilizing chambers, each of which receives steam from a single steam generator. A single system controller provides for the on-demand sharing of system resources among the two sterilizing chambers. The tabletop steam sterilizer system also includes a water distiller system that receives water from the municipal or other non-distilled water supply, converts that municipal or other non-distilled water to distilled water, and supplies that distilled water to the sterilization chambers to carry out a sterilization cycle. Exhaust from the sterilization chambers may be recycled back to the distiller system for processing by the distiller system back into distilled water for subsequent sterilization cycles.
