Title: Heat-resistant low alloy steel casting and its heating treatment
Inventor: MORIKAWA MINORU
IPC: C22C38/00
Filed: 1978-02-10
Abstract: PURPOSE: To raise the strength of low alloy steel casting at high temperatures as well as minimize the developing rate of creep cracks by the procedure in which a Cr-Mo-V low alloy steel casting is heated in the temperature range where carbide crystallizes out, and then subjected to a more than one repeated homogenizing and tempering treatment.  
     CONSTITUTION: The heat resistant low alloy steel casting contains 0.05 to 0.40% C; < 1.5% Si, < 3.0% Mn, 0.5 to 3.0% Cr, 0.5 to 3.0% Mo, and 0.10 to 0.20% V, together, as needed, with <0.50% Ni or 0.005 to 0.10% at least one of Ti, Al, Zr, Nb, and Ta, which serve to improve toughness and also to make finer crystal granules. The steel casting is heated to 230 to 460°C or 670 to 780°C at which carbides crystallize out, and then subjected to a more than one repeated homogenizing and tempering treatment in order to convert all constitution into the fine structure of bainite or bainite and ferrite. Thus, a heat resistant low alloy steel casting which is excellent in high temperature strength and also small in the developing rate of creep cracks can be obtained, which is suitable for the casing material of steam turbine.

Title: Fuel cell power generation system
Inventor: TAGUMA YOSHIYUKI
IPC: H01M8/04
Filed: 1990-01-23
Abstract: PURPOSE:To prevent penetration of air into a steam separator at the time of stoppage for preventing corrosion of pipings by providing a pressurizing means for maintaining the steam separator where cooling water is separated into a gaseous phase and a liquid phase and the gaseous phase part of the steam separator higher than an atmospheric pressure by a pressure of inactive gas. CONSTITUTION:When a system is stopped, reaction of a fuel cell main body 1 is stopped to eliminate heat generation, where the temperature of cell cooling water in a steam separator 3 is reduced, and the main body 1 is cooled. The pressure of the separator 3 is also reduced corresponding to the temperature fall of cooling water, and when this pressure becomes lower than 0.2kg/cm<2>, for example, nitrogen is supplied from a nitrogen facility 20 of a pressurizing means 24 to a gaseous phase part 5 of the separator 3, so the pressure in the separator 3 is kept constant at 2.0kg/cm<2> in this case. At the time of stoppage and storage, cooling water is kept at 50-60 deg.C, and the pressure in the separator 3 is maintained at a nitrogen pressure. The separator 3 is thus prevented from being at a negative pressure, thereby suction of surrounding air as a cause for corrosion can be prevented.
