Title: Method for treating heater drain from power station
Inventor: UMEMOTO SHOGO
IPC: C02F1/44
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To prevent a fine particle of iron oxide from being entrained into the steam generator of a power station by including oxygen into a heater drain from the power station in a stage preceding the arrival of the heater drain at a filter and changing the fine particle of iron oxide to such a shape as to be captured by the filter and removed. SOLUTION: A steam from a lower pressure turbine 31 is restored to water with the help of a condenser 32 and this water is sent to a condensate desalting device 34 by a pump 33 to desalt the condensate. This desalted condensate is heated by a low pressure feed heater 36 and the thermally treated condensate is sent to a steam generator through a high pressure feed heater or the like. In this case, a filter 37 with an oxygen injection installation is installed on the low pressure feed heater 36 and the heater drain is filtered using the filter 37. Further, a filtered water obtained by removing impurities composed mainly of a fine particle of iron oxide from the heater drain, is caused to join with a condensate-treated water heated by the low pressure feed heater 36. Thus it is possible to prevent the fine particle of iron oxide from being entrained into the steam generator.

IPC: G10K11/162
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To reduce noise, the weight and the cost by constituting the member with the surface layer sound absorbing section which is formed to a prescribed shape by nonwoven fabrics and the inner section sound absorbing section which is constructed by laminating the member in the surface layer sound absorbing section and making the density of the surface layer sound absorbing section higher than the density of the inner section sound absorbing section. SOLUTION: The member is constituted of a surface layer sound absorbing section 1 which is formed in a container shape and an inner section sound absorbing section 2 which fills in the section 1 leaving small air layers 3. The section 1 is formed by sheet shape nonwoven fabrics in a prescribed shape. If the fabrics are made of thermoplastic fibers such as PET fibers, the section 1 is easily formed by a press molding. As mentioned above, the density of the section 1 is set higher than the density of the section 2. By increasing the density of the section 1, the air-diffusibility resistance is increased, the apparent density of the entire sound absorbing member is increased and even though the density of the section is lower, a high sound absorbing characteristic is secured.

IPC: G01N25/18
Filed: 1988-09-26
Abstract: PURPOSE:To eliminate the necessity of troublesome sensor cleaning works and, at the same time, to reduce the danger of toxicity subjecting to the operator at the time of non-measuring by throwing out the sensor formed separately from an measuring instrument main body when measurement is completed. CONSTITUTION:A holding body 3 which fixes lead wires 2a-2d connected with a heat producing body 1 is provided and a terminal 4 is formed at the other ends of the fixed lead wires 2a-2d as a sensor S so that the sensor can be disposable. The heat producing body 1 is brought into contact with a fluid while the sensor S is put in a container, etc., filled up with an object to be measured and the body 1 is caused to produce heat by an electric current supplied through the lead wires 2a-2d so that heat is transferred from the body 1 to the fluid. When the temperature and heating value are calculated from the value of the supplied current and a measured voltage value, changes of various physical properties of the fluid can be measured from the calculated temperature and heating value of the heat producing body 1 and the temperature of the fluid. Therefore, the man-hour required for cleaning the sensor S and the danger of the operator can be reduced.
