摘要： PURPOSE:To reduce the heat exchange area of a low pressure supply water heater and raise the thermal efficiency by pouring the high temperature liquid leaking from a supply water pump shaft sealing device to the suction side of a supply water pump. CONSTITUTION:An intermediate extraction pipe 6 is connected to a piping 26 that connects a drain tank 18 and the suction side of a drain pump 20 through a piping 7. With this constitution the high temperature shaft sealing water of a supply water pump 17 the pressure of which is reduced and which is leaking has its pressure boosted by the drain pump 20 and is recovered to the suction side of a supply water pump 17. In this way the high temperature liquid is not returned to a low temperature supply water heater 16, and the heat exchange capacity in the low pressure supply water heater 16 is reduced, and the area of its heat exchange is made thereby smaller. And, the heat recovery of the high temperature water is carried out on the high pressure side of a steam turbine, and the thermal efficiency is improved as that in the Rankine cycle.

摘要： PURPOSE:To prevent sticking of fats and oils and org. components to a hollow yarn membrane by constituting the clad precoater of an iron clad generator and a clad injection piping and connecting the clad injection piping to the inlet side of a hollow yarn membrane filter device. CONSTITUTION:An inlet sop valve 5 and an outlet stop valve 9 of a condensate filter device 7 are fully closed and an iron clad injection device 24 is operated to form iron clad. The clad is captured by the hollow yarn membrane in the filter device 7 and the condensate returns to the injection device 24 when the iron clad is injected together with the condensate into an inlet pipe 6 by an injection pump 25. The clad is thus precoated on the filter device 7 and the fat and oil components in the condensate stick to the initially precoated clad and, therefore, the sticking thereof to the pores of the hollow yarn membrane do not arise. The abnormal increase of a differential pressure is, therefore, obviated and further, the clad is removed from the hollow yarn membrane by backwashing water. Since the fat and oil components are simultaneously removed from the membrane, the differential pressure is restored.

摘要： PURPOSE:To prevent environmental pollution while the efficiency of heat transfer of condenser tubes is recovered and maintained by circulating spongy balls impregnated with a fungicide for slime-forming bacteria and a chemical for removing slime. CONSTITUTION:Both the inlet valve 6 and outlet valve 7 of a condenser 1 are totally closed. From a chemical injector 5 chemical preparations are injected into cleansing bells in a ball-collecting device 4, and by actuating a pump 5 the balls 13A impregnated with the chemicals are sent to the condenser 1. The balls 13A strip the condenser tubes 2 of slime 12 adhering thereto and eliminate it. The balls 13A thereafter are returned to the ball-collecting device 4 through a ball collector 10 and circulated. After complete elimination of the slime 12, the operation of the chemical injector 5 is stopped and the seawater is sampled in monitoring the concentrations of the residual chemicals so that, when necessary, the effluent is disposed of in ocean 9 or in the neutralization chamber 8. This system of cleansing lends itself to prevention of environmental pollution and recovery and maintenance of the efficiency of heat transfer as well.

摘要： PURPOSE:To increase holding capacity and to realize high vacuum operation of a condenser, by providing a steam ejector and a steam condenser to a water sealed rotary vacuum pump as a vacuum ejector for a condenser. CONSTITUTION:A steam ejector bypass valve 10 is closed, and driving steam is fed to a steam ejector 4 provided on the upstream side of a water sealed rotary vacuum pump 11, passing through a driving steam pipe 9, via a driving steam check valve 8 and a pressure reducing valve 17. The steam ejector 4 is operated by the steam to vacuumize the inside of a condenser up to the rated vacuum of it. Further, gas in the condenser 1 is sucked by the suction effect of a steam ejector 4. The driving steam and the sucked gas are mixed with each other, flowing into a steam condenser 5, exchanging heat with cooling water 6 at the inlet of a steam condenser, being condensed, and is discharged to a separator tank 12 by the water sealed rotary vacuum pump 11. With such an arrangement, holding capacity is increased by the steam ejector, and the capacity of a condenser can be increased without changing the water sealed rotary vacuum pump. Accordingly, high vacuum operation of a condenser can be taken place, suppressing the decrease of plant efficiency at the minimum possible.

摘要： PURPOSE:To maintain a flow rate in a condensate line at a fixed value and to execute stable operation by adding a flow meter, a flow rate controlling valve, and a controlling device therefor to a by-path pipe line provided in parallel to plural filters. CONSTITUTION:A flow meter 42, a flow rate controlling valve 51, and a controlling device therefor are provided as constituting members of a by-path pipe line enabling flow rate control during operation using the by-path line. Namely, in the case of complete by-path operation, the flow meter 41 and the flow meter 42 are controlled so as to obtain a set flow rate inputted to a setter 103. Further, as the by-path flow rate controlling device is required to be in a nonoperating condition when the whole filters 11 are in operation, a connector 120 is provided to the upstream side of a controller 123 where the signal from the controller 102 is inputted to detect whether one filter 11 is in suspended condition or not by a detector 121. When there is a suspending filter, the connector 120 is operated and the signal from the controller 102 is transmitted to the controller 123.

摘要： PURPOSE: To control easily the supply of feed liquid to be treated to each filter by providing a pipe loss generating device to branch pipes connecting plural filters having different liquid passing times which are installed in parallel between an inlet header and an outlet header with each of above-mentioned header.
CONSTITUTION: A flowmeter 14, an inlet valve 16 and an orifice 56 for generating pipe loss are provided to an inlet branch pipe 12 for introducing the feed liquid to be treated flowing in an inlet header 10 into filters 20A, 20B...20N. The operating condition of each filter 20A, 20B...20N is inspected by detecting the differential pressure of each filter obtained from a differential pressure gage 34. Since the feed liquid to be treated passes through the orifice 56 in the flow of each series, the differential pressure caused by piping, valves and orifices is increased as compared with before and the differential pressure in each filter is relatively decreased. In this way, the flow rate to each filter can easily be controlled.
