摘要： PROBLEM TO BE SOLVED: To provide a combined power plant and a method of operating the power plant with saved space and reduced cost.
SOLUTION: In this combined power plant, feed water reduced in the amount of dissolved oxygen in a drum 33a for low-pressure, is sent to lines Lb and Lc for medium-pressure and high-pressure, respectively and steam is generated to drive a medium-pressure turbine 23 and a high-pressure turbine 24. At this time, a deaerator 50 for reducing dissolved oxygen in the feed water may be included on the rear-stage side of the drum 33a for low-pressure. In addition, feed water is sprinkled with a spray within the drum 33a for low-pressure and a heat-exchange fin may be formed inside the drum 33a for low-pressure for allowing the feed water to flow down on the surface of the fin. Further, it can be so configured that pressure within the drum 33a for low-pressure is reduced or that high-pressure steam is extracted for making the feed water flash-evaporated.

摘要： PROBLEM TO BE SOLVED: To easily remove a vapor-oxidated scale densely sticking on a metal surface in a short time, with no drainage process such as COD process. SOLUTION: There are provided a first means where a tight fitting force at an interface between a vapor-oxidated scale and a metal surface of base material is decreased by coating or other means, with a processor liquid jetted, a second means to cause a compression or tensile stress on the inside surface of the scale where the sticking force at the interface is decreased by allowing temperature difference between the scale and the base material, and a third means to remove the scale where the fitting to the base material surface is released because of buckling separation and the like under the applied stress. The first, second, and third means are held between a pair of travel means running along a scale formation surface while connected together as one body, for simple and succeeding scale removal.

摘要： PURPOSE:To obtain enough descaling performance at normal temp., to eliminate the need for pH treatment for waste liquid and to improve safety by adding nitrate ions to the aq. soln. of phosphate to control the pH in a specified range. CONSTITUTION:The descaling agent is prepared by adding nitrate ions to one or more kinds of aq. soln. of phosphate and controlling the pH of the soln. to 5.5-9.5. The concns. of phosphate and nitrate ions are specified to from about 0.1 to 50%. Or, the descaling agent is prepared by adding nitrate ions to one or more kinds of chelate agent and controlling the pH to 5.5-9.5. Or, one or more kinds of chelate agent and nitrate ions are added to one or more kinds of aq. soln. of phosphate. Though each of phosphate, chelate agent and nitrate ions in the descaling composition has weak or no descaling property by itself, the combination of these gives the function to remove scale incorporating metal oxides from metal surface. This descaling composition is neutral and required no neutralization treatment after descaling.

摘要： PURPOSE:To realize a measuring method requiring no test piece and capable of obtaining a result reduced in irregularity, by measuring the curing time of an org. adhesive from the relation between the change in the transmissivity or absorbancy of an infrared absorption spectrum and an elapse time. CONSTITUTION:Measurement is performed according to the following process. That is, an adhesive is mixed to be held between two window panels and set to a specimen chamber in a first process and an infrared absorption spectrum is measured to obtain initial data in a second process. In a third process, the infrared absorption spectrum is again measured after a definite time to confirm a wave number region changing in transmissivity or absorbancy. At this time, some epoxy adhesive has a wave number region present in the vicinity of about 3,400cm. In a fourth process, the timewise change in the infrared absorption spectrum is measured and, in a fifth process, the curing time of the epoxy adhesive is calculated from the relation between the transmissivity or absorbancy of the wave number region having a change and an elapse time. By the above mentioned method, the material cost and processing cost relating to the formation of a test piece become unnecessary and the irregularity in a measuring result is reduced.
