Abstract

Sea water contains a lot of marine life. If the growth is not inhibited marine life, it can be attached to the installation path (biofouling). Later, as a result of this biofouling will reduce the efficiency of installations through which sea water tersebu t and will add to the cost of production units. Chemical liquid sodium hypochlorite (NaOCl) produced by chlorination plant breeding serves as a barrier to marine organisms. This fluid is produced in the chlorine generator cell through a process of electrolysis of seawater. In fact, electrolysis of sea water also produce side reactions. Namely the deposition of minerals such as magnesium (Mg) and calcium (Ca). As a result, the cell voltage chlorine generator will increase in the use of the same current. Therefore, it is necessary that the process of cleaning acid cell kembalibersih chlorine generator. Reference implementation of the process of cleaning acid that is based on the operating time and based on the voltage. Commissioning of the data, has been conducted several times a dry acid process based on the operating time of 250 H / ± 10 days. But the acid cleaning process is inefficient and ineffective. Therefore, the new reference is made in the implementation process of cleaning acid, wherein the voltage value menjad iacuannya. Several advantages, including the total cost of implementing the dry acid in cycle 1 (one) month more efficient, improve the efficiency and effectiveness of cleaning acid and time flexibility in the implementation process of cleaning acid.

Abstract

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.

Abstract

Material Screen Wall tube superheater PLTU UBOH Banten 3 Papyrus that has received the damage unit 1 material form fatigue that happened in permukaanya so that these plants need to be fired withdrawn for some time. Considering the importance of the role a power plant in the context of fulfilling present, management needs national, of course dismissal plant operations should be avoided because such as this can lead to a loss for both sides producers and consumers. The importance screen wall tube superheater which functions as a partition or curtain from superheater tube, in writing bachelor theses will test material screen wall tube superheater with various testing method of analysis of other chemical composition (spark oes), analysis of violent methods vickers),SHEM and EDS and analysis metalografi where it is hoped that it can be expressed the analysis of the process was badly and the reasons why components that can be destroyed and damaged.

Abstract

Gas Removal System at the Center for Geothermal Plant (PLTP) plays an important role as Non Condensable exhaust gas (NCG) in the condenser, to keep the condenser pressure remains low. Therefore steam expanded in the turbine will be condensed by water that is on the condenser.
