<![CDATA[The use of electricity in modern life today is a necessity and demands that can not be separated from everyday activities. Indramayu power plant which has a capacity of 3 x 330 MW is one of the coal-fired thermal power plant that supplies the system interconnect JAMALI (Java, Madura, Bali). Thus generating performance reliability is a must. In the production process kapaitas Indramayu with 3 x 300 MW, there are many tools that support to optimize the power production process, whether it is the main equipment and auxiliary equipment. The main equipment at this plant, among others such as boilers, turbines, generators and condensers. Indramayu contained cooling water cycle that serves to cool the various systems, for example: as a generator coolant, lube oil coolers, etc. In the cooling water cycle, there are a medium for transferring heat from a hot medium into a cold media, the tool is called Heat Exchanger (HE) .Heat discussed exchanger using sea water cooling medium, so it is prone to dirty / clogged. Therefore, before entering the heat exchanger there is a filter called debris filter Heat Exchanger. In pengoprasian debris filter Heat Exchanger there are many obstacles, one of which is the overflow of water in the sump tank which would cause flooding on the ground floor and the matter will be discussed in this project so that it does not reoccur.]]>

<![CDATA[Condensate water is the main ingredient in the process of generating steam in the power plant condensate water uap. Therefore must have a good quality so it does not cause damage to the equipment - equipment such as pipes, tubes, valves and others. To produce water quality condensate desirable it is necessary chemicals include phosphate, ammonia and chemical hydrasin. Material is injected into some equipment such as deaerator, steam drums and others. On this occasion the discussion is about the injection of chemicals phospat. Material the chemicals injected into the water condensate (feed water) which will be precisely in the boiler to the steam injection process takes drum. For pump chemicals from the tank in order to get to the steam drum. Therefore the pump and the output pipe leading the steam drum to be reliable so it does not interfere with the injection process resulting in the boiler water quality does not match the prescribed standards that disrupts the production of listrik.Namun on the way there has been a disruption especially at pipe outlet (discharge line) to the steam drum is clogged (plugging) .This occurs because after the injection process there are still remaining - the rest of phosphate in the pump, pipe valve outlet and then dries and crystallizes as kapur.This happens especially when the power is turned off for a long time (over houl). From the above problems it is necessary to add the channel for flushing (flushing) on the pump and the discharge channel leading to the steam drum, especially when the power will be off for a long time so there is no plugging in the pipe leading to the pump outlet steam line drum. The addition of the plumbing connected condensate (from discharge CEP) to the pump inlet pipe phosphate.]]>

<![CDATA[Reliable power generation can not be separated from the reliability of the power plant system integration. At the power plant, in particular all the power plant system reliability must be maintained so that no damage is fatal. Especially the instrument air system which is driving tools instrumentation. At indramayu power plant with an installed capacity of 3 x 330 MW nearly all settings instrumentation equipment sourced from compressed instrument air. This system is derived from the rotary screw compressor manifold floaded oil. In the instrument air system contained additional equipment to maintain the quality of the air produced is water dryer. But the fact of compressed instrument air quality is not good and still below the standards of ANSI / ISA-S7.0.01-1996. The output pressure of the compressed air system is also less. Normal operating pressure is 0.75 - 0.8 Mpa, but in actual field conditions of water stress on the receiver tank just 0:57 -0.64 MPa. This happens because of the existing compressor 5 only 3 that stand by. The performance of the compressor that is running downhill. It can be seen from the resulting pressure dropped from 0.85 MPa to 0.76 MPa. Based on these problems required the study and modification of compressed instrument air supply to find the best solution.]]>

<![CDATA[Belt conveyor is a device used to transfer coal combustion chamber (furnice) in Steam Power (power plant). In the Indramayu power plant conveyor conditions in the field often occurs over tracking the conveyor belt and the belt results in the termination of coal burning. A voltage that is too large will cause the working of the belt conveyor to be heavy so that it can lead to broken shaft and idler pulley. While the voltage is too small to make the cause of the conveyor belt out of the track resulting in slippage into the pulley. The voltage on the conveyor belt must be known with certainty to prevent failed operations on the conveyor. In this case penlis will analyze the voltage for each operating capacity of belt conveyor C4 using the standard CEMA (Conveyor Equipment Manufacturers Association) 6th Edition, 2002. So with the proper voltage, the operation of conveyor C4 can walk normally.]]>

<![CDATA[In the process of production of the power plant cooling water system has a very important role to change the vapor phase from the expansion turbine into water stored in Hotwell. The condenser is equipment which becomes the venue for the process, but keep in mind the level of cleanliness of the condenser becomes an important factor because it can reduce the heat transfer in the condenser and reduces the cooling process. Moreover, it can also result in other equipment eg in CWP (circulating water pump) increased vibration due to flow of pumped water can not flow the maximum because of blockage in the tube-tube condenser can for garbage, excrement of marine life, or the rubber peeled off later cover tube-tube condenser. This will also result in the efficiency of the unit as well as derating occurs during the process of cleaning the condenser. Cleaning the condenser lowers vibration values CWP 2C Motor inboard side Axial from 6754 mm / s to 1080 mm / s and horizontal outboard motor side of 4645 mm / s to 2827 mm / s according to ISO 10816-3 standard vibration value falls within the normal conditions of operation .Kenaikan dry vacuum condenser before becoming 695 mmHg 683 mmHg after cleaning the condenser this is because the maximum heat transfer process. Mass amounts of water cooling which increased from 15133.88 kg / s into 19221.1 kg / s cause the temperature difference cooling water in and out decreased from before cleaning the condenser is 13 0C becomes 8.6 0C.]]>
