Abstract

The purpose of this paper is to calculate boiler performance by knowing energy losses during uap production.Technical analysis on the boiler is needed, as an effort to increase efficiency and know how much energy iswasted as a loss. Factors causing the greatest heat loss / heat loss in the boiler include: "heat loss due to dryflue gas, uap content in the flue gas, water content in fuel, water content in air supply and others". Heat loss /heat loss or also can be called energy loss is one of the important factors that is very influential in identifyingthe efficiency of the boiler.For that analysis study is carried out with the calculation of heat loss in order todetermine the magnitude of performance decline and the causes of decreased performance. Based on data andanalysis of the direct method it is known that the highest energy loss is 26.6% with an efficiency of 74.5%.There needs to be an improvement in the control of the fuel settings and the incoming air optimally by usingthe Oxygen Trim Control which functions to measure the oxygen concentration in the chimney andautomatically regulates the oxygen in the air entering the burner so as to produce combustion with optimalefficiency. And by using an economizer on preheating feed water temperature can increase boiler efficiency

Abstract

V-Notch 900 is a device that has a triangular-shaped gap with an angle of ninety degrees. Tanjung Seumantoh Palm Oil Mill does not yet have a tool to measure the discharge of diluent water used at press stations, so there are often problems with the composition of crude oil that is not ideal due to too much or too little diluent water used. This study aims to determine the magnitude of the effect of using V-Notch as an indicator of crude oil diluent water regulation at Tanjung Seumantoh Palm Oil Mill PT. Nusantara I Plantation so that the comparison after and before Tanjung Seumantoh Palm Oil Mill using V-Notch at the press station is known. The results of this study show that the composition of crude oil before the application of V-Notch is 33:45:22 (Oil:Water:Nos) By using press number 3, 1 and 2 without knowing how much diluent water is used. After the application of V-Notch to 39:40:21 using pressan number 3, 1 and 2, it is known that the amount of diluent water used is 16.2 tons / hour. This indicates that the application of V-Notch can affect the composition of Crude Oil at the Press station to be ideal according to company standards. The oil content in palm fibers and palm kernel is 50%-55% and 40% respectively and the ideal crude oil composition is 40%Oil: 40%Water: 20%Nos.
