Abstract

Power Plant is a type of thermal power plant that is widely used, because of its fuel efficiency is good and easily obtained thus producing electrical energy economically.One Supporting Components Boiler ie Furnace, Steam Drum, Superheater, Water Heater, economizer, Safety Valve, Sootblower. Sootblower a boiler auxiliary equipment which serves to clean the dirt produced from the combustion process that is attached to the tube wall pipes, superheater, reheater, economizer, and water heater. The goal is to keep the heat transfer takes place properly and effectively. Long Retractable type Sootblower placed in superheater, Reheat, and economizer. This type is on stand-by condition is outside, and when the work will go spinning and turning it back out. if on the flue gas temperature is still very high, causing Sootblower bent by heat if it is not pulled out.

Abstract

Coal power plant is designed based on a particular coal quality. Changes in coal quality will affect the quality of combustion and changes in combustion air. This study will describe the analysis of changes in coal quality on the ability of the force draft fan covers theoretical air, the percentage of air, capacity and force draft fan itself, and to analyze whether the capacity of force draft fan that existed at the time the design is adequate to the quality of coal that apply now .Berdasarkan calculation of theoretical air force draft fan air is 306 300 kg / s with the design power of 811 909 kW. Calculation of actual data shows the average air flow in the period from March to May was 307 610 kg of air / s. The capacity is still inadequate because of changes in the quality of the coal used is not too large.

Abstract

Analysis of the influence of alloying elements on the composition of the appointment in the womb does not spread evenly on the steel samples of laterite, this is possible because the steel sample ketebalanpadadaerah laterite. At the micro structure of steel material hasilnyaadalahdaerah laterite classified as low, medium, high and this is caused because the carbon content in the area of ​​steel material laterite percent lower alloying element content. Results microscopy analysis on steel samples of laterite by viewing the crystal grains with pembesaranmasing each 50 μm and 30 μm, showed the homogeneity of grains spread evenly. Basically the results of the domestic industry has been quite satisfactory in the quality control process pembuatannya.Namun seen in the test object lateritbentuk steel microstructure in the steel material lateritkurang evenly. In the test of the strength of the metal material has an advantage in the Brinell hardness test.

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.

Abstract

Condenser is one of the important tools in PLTGU Pond Lorok. Condenser is a heat exchanger that serves to condense the steam turbine output becomes condensate water which would then be circulated back into water filler with sea water as coolant medium. The increase in condenser pressure showed a decrease in the performance of the condenser. Therefore it is necessary for cleaning the condenser. Cleaning the condenser in the online condition can be done in an effort to lower the condenser pressure. From the condenser cleaning results during March and April condenser pressure can be lowered by 1.1 mmHg Abs - 4.3 mmHg Abs. With the reduction in the condenser pressure of ± 4 mm Hg Abs then the power turbine will rise by 1 MW, it indicates that the unit more efficient.

Abstract

In the world of power generation are intimately associated with the boiler and HRSG (heat recovery steam generator), the equipment is functioning as modifiers of water into steam that drives the turbine so that it can turn a generator and produce electricity. HRSG section are instrumental in changing the water into steam is the drum, the drum has a high pressure and temperature so that the equipment must always be inspected every overhaul. Inspection, among others pengkuran drum wall thickness on using Ultrasonic Thickness Testing, this inspection aims to determine the condition of the drum. From the results of these inspections at some point find there is some corrosion on the walls. Then calculated the minimum thickness of the drums and the rest of his life estimates using Standard ASME Boiler and Pressure Vessel Code.

Abstract

IGV (Inlet Guide Vanes) is a component of the main supporters of a GTG (Gas Turbine Generator), IGV serves as a regulator of the flow rate of air entering the compressor when heading to the GTG start up and during operation. In operation there is the possibility of interference with the IGV that can make the performance of GTG decreased or even the most fatal trip can download the GTG. Problematic sources of interference from an IGV can come from various sources. To determine what resources are causing problematic function of IGV required an analysis method that is able to parse problems / disorders that actually happened. The method used is RCFA (Root Cause Failure Analysis), RCFA an analysis method that is able to break down the root cause of the occurrence of a problem / nuisance. By using the method RCFA expected problems can be resolved with due diligence and it is possible to not reappear at a later time.

Abstract

The boiler is functioning equipment turn the water into steam by heating. Existing plants are specified in the supply of electrical energy required by konsumen.Effisiensi is one of the many parameters used to assess whether or not the performance of a boiler.Metode used in the calculation of boiler efficiency is the input-output method and heat losses by the aim of knowing the cause of the decrease in efficiency. Suralaya boiler efficiency analysis unit 5 meliputianalisaawaloperasidananalisasetelah terakhir.Dari overhaul both the analysis of these calculations will be elaborated based on the method of heat losses, thus resulting to a conclusion after comparison. Based on the analysis, the efficiency of the boiler when the last overhaul lower than initial efficiency of development. From the calculation of the authors analyzed the causes of decline in the efficiency and the conclusion of the decline 0.71% boiler efficiency and operation early last overhaul.

Abstract

The function of the gas turbine casing insulation is to reduce the rate of heat transfer from the gas turbine to the surrounding air, preventing the risk of fire, prevent the risk of operator safety and other hazards. Based on the findings of a team of thermography in PLTGU Grati, it is known there are many points of leakage of heat (hot spots) in a gas turbine casing. One effect of this is the emergence of hot spots burning wires and thermocouple terminal BPTdi gas turbine, which led into a gas turbine trip. Several methods can be used to handle the emergence of hot spots in the insulation casing, is to replace the insulating material, adding thickness (Δx) isolasiserta modify the shape and position of isolation. After studying a variety of sources, it is known that the ceramic fiber insulation blankets is a type of casing the best and most appropriate to isolate the gas turbine casing in PLTGU Grati. In addition, of several methods that can be used to handle hot spots in the insulation casing, then the most effective way is to modify the shape and rearrange the position of the insulation to fit the shape of casing gas turbine (adjusted for standartnya), so there is no longer hot spot appear, so that the gas turbine can avoid the risk of trip.
