Abstract

Analysis of Effect of Plugging Evaporator Against Performance Desalination Plant Unit 2 PLTGU Gresik is the analysis that discusses the effect of plugging tubes evaporator on the performance of Desaliantion Plant Unit 2 Type MSF-Once Through in PLTGU Gresik by calculating heat transfer in the evaporator and tubes Condenser, in which the calculation includes calculation before plugging the rate of heat transfer, heat transfer rate after plugging and loss of thermal efficiency at the desalination plant due to the effect of plugging the evaporator. After calculating heat transfer occurs, then analyze the results of the calculation of how much influence the evaporator tubes plugging of the desalination plant performance. Where the results are compared with the theoretical calculations of data - data that is in the specification Desaliantion Plant Unit 2 PLTGU Gresik type MSF-Once Through, whether appropriate or not then draw conclusions from such comparisons.

Abstract

PT Indonesia Power UBP Perak RoW have six gas turbines with a capacity of 100 MW each in which the fuel used is natural gas. One of the things that is very considered in the generation of electricity is the efficiency of an equipment, the observation that we encounter in the gas turbine efficiency is still relatively low, wasting fuel and have high production costs. To overcome this, the existing power plant should need to improve the efficiency of the total system that will reduce fuel consumption and production costs. In this case, one way to improve the efficiency of gas turbine type M701 D by adding a fuel gas heater (FGH) to absorb most of the heat in the exhaust (waste heat) through the Rotor Cooling Water (RCA) utilized to heat the fuel before entering into the gas turbine, without reducing the functionality of the cooling system of the gas turbine is even improve the functioning of the RCA itself, it aims to minimize waste heat are dumped into the atmosphere is not too large so that the efficiency of the system at the Gas Turbine increased overall, lower fuel consumption so that the production cost becomes less. Having done a comparison of calculation before and after FGH fitted with a variety of load Gas Turbine in getting power output increase by 1.11% - 1.37% and the efficiency of gas turbines rose by 0.25% - 0.39% and a decrease in heat rate ranging between 0.8% - 1.47%.

Abstract

The steam turbine generator is the main equipment working at high temperature and pressure so it is very important to do regular maintenance to guarantee keandalannya.Pemliharaan is a simple routine inspection, inspection mean and serious inspection. Serious when turbine maintenance inspection (demolition total) there tubin demolition work and the valve casing turbine in penangananya requires a special instrument called boltheater. The tool is a tool for the disassembly bolt turbine casing and turbine valve with the principle of heating the bolt, causing expansion and further used for disassembling the bolt. Mertode previous boltheater operation is manually which has several shortcomings kekurangan. So to avoid the need for a remote control and one of them is a remote control system based on SMS controller. Automatic control has the advantage of efficient use of personnel which impact on the efficiency of maintenance costs, speed up the process of work (time efficiency) and reduce the risk of workplace accidents during the process of disassembly turbine casing and turbine valve. The existence of the efficiency of the time when the overhaul will increase the chance of generating units operate. Opportunity for all operating units of the plant affects the value of EAF (Equivalent Availability Factor). This is a measure of the success of a plant in the supply and sell electricity.

Abstract

Suralaya Power Plant using Mill Pulverizer MPS-89 as a tool for coal-fired nourishing that will be transmitted to the boiler fuel in. Coal miners To sublimate Mill Pulverizer MPS-89 using Home Wheel Tire and Grinding Ring segment. Grinding Ring segment digerakan by motor, while Home Wheel Tire follow Ring Segments and relies on cushioning material. The damage safeguards Home Wheel Tire because kemasukkan dust from coal, will cause stopping operations of mill pulverizer, thus affecting

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.
