Abstract

Center Steam Power (power plant) is a type of power plant that is the most common and most of the electrical energy needs on the island of Java and Bali are supplied by the plant species. Broadly speaking, the system of steam power plant (power plant) is composed of some major equipment and support equipment. One part of the steam power generation equipment that plays a key role is the Boiler Feed Pump (BFP). BFP main function is to pump the fluid from the deaerator heading to Steam Boiler Drum through through High Pressure Heater and economizer. BFP in Muara Karang power plant unit 5 uses an electric motor as a pump drive and media use as transmission fluid coupling of the pump. BFP magnitude greatly affect the efficiency losses (losses) of the component - the component. Therefore, the magnitude of losses (losses) that occur need to be analyzed to gain efficiencies actual Boiler Feed Pump. This research aims to study and analyze the depth of the losses in the system BFP (Boiler Feed Pump). The results are used to determine the value of losses on some components of the system BFP. The results showed that the value of the copper losses and the loss of magnetization of electric motors at 216.051 kJ, losses due to fluid friction in the pump for 1424.8694 kJ, the losses can not be taken into account such as the pump bearings, clutch bearings, motor bearings, radiation and Lubricate the coupling of 262.3645 kJ.

Abstract

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.

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.
