摘要： PURPOSE: To obtain a chemical heat pump system which can amplify heat up to a particular high temperature by using a metallic hydride, as an occlusion alloy and accumulate a large amount of hydrogen energy without melting the hydride in the case where the metallic hydride is exposed at a high temperature. CONSTITUTION: Heat of 300 to 500 deg.C is thermally amplified at 1000 to 1200 deg.C, using heat of reaction wherein a specified metallic alloy reacts with hydrogen, and a metallic hydride capable of accumulating a large amount of hydrogen energy is used. As an example of this metallic hydride, a Ti-Cr alloy having Cr content of 0.2 to 15wt.% is suitable for hydrogenation reaction under high temperature. In each element in a pressure vessel for pyrogenetic or criogenic reaction comprising a chemical heat pump system, a heat-resistant alloy tube 1 as a heat-exchanging part is arranged at the central part thereof and a hydrogen occlusion alloy 2 is arranged around the tube 1. In addition, the periphery of the hydrogen occlusion alloy 2 is covered with a holder 3 formed of porous ceramics such as sintered metal, and for the purpose of increasing the heat efficiency of this element; furthermore, the periphery thereof is covered with heat-insulating material such as a microtherm.

摘要： PURPOSE:To obtain a heat insulating structure stable at a specific high temp. and reduced in the deterioration of heat insulating capacity by graphitizing a preform obtained by knitting a carbon fiber low in heat conductivity into a three-dimensional shape and coating the surface of the graphitized preform with dense graphite. CONSTITUTION:A preform obtained by knitting a carbon fiber low in heat conductivity into a three-dimensional shape is graphitized and the surface of the graphitized preform is coated with dense graphite to obtain a heat insulating structure suitably used in a high temp. gas furnace for taking out high temp. heat energy from a nuclear reactor and stable at temp. of 1000 deg.C or higher and reduced in the deterioration of heat insulating capacity. At this time, as the carbon fiber, a PAN or pitch type carbon fiber is used and the preform is produced by baking under vacuum and the graphitized preform is formed so that the density thereof becomes 0.17g/cm or less. Dense graphite is applied to the surface of the preform by CVD and the thickness thereof is set to 10-1000mum.

摘要： PURPOSE:To use a joining material in the normal temp. and specially high temp. places by specifying the compsn. of the joining material between graphite material and metallic material. CONSTITUTION:The degree of vacuum of a heating furnace which is kept in the high temp. >=1,100 deg.C is made to >=10 Torr. The joining material made of Ti, Ni and Cu having the ratio of a compsn., by wt%, 69-57 Ti, 24-20 Ni and 7-23 Cu is used and the joining is performed in an argon atmosphere in the heating furnace. In this way, the graphite 1 is joined to the metallic material such as a Mo plate 3 with the constitution of the graphite - the joining material - the Mo plate.

摘要： PROBLEM TO BE SOLVED: To provide a heat exchanger endurable against large capacity heat exchange of several 10 to 100 MW, and capable reducing the size, in a high temperature high pressure condition environment of 1,000 °C × 2 MPa or more of solution, a gasified strong acid, and halogen.
SOLUTION: This heat exchanger is superior in anti-corrosiveness and high temperature strength, and is made compact, by joining and laminating a block element of orthogonally and oppositely arranging a large number of circular inflow channels of a heat exchange medium part, by using a ceramic raw material strong against the strong acid and halogen such as concentrated sulfuric acid and hydrogen iodide.
