Abstract

A biomass co-firing program has been put in place at power plants by PLN to support policies relating to the renewable energy mix. The extent to which continuous biomass co-firing at various generating load conditions will affect the performance of boiler equipment is unknown. The goal of this study is to ascertain the effects of ongoing biomass co-firing on the efficiency of boiler equipment under various generating load scenarios. An observational approach as well as interviewing techniques were used to collect the data. By hand, using Microsoft Excel software, the calculation value for a specific fuel consumption and net plant heat rate is found. The operating parameters of the boiler equipment performance are then compared with benchmark or commissioning data. The performance of boiler equipment (medium speed mill, boiler fan, air preheater) is unaffected by the co-firing process, and all of its parameters remain within acceptable bounds. As can be seen from the Mmdium speed mill motor and boiler fan flows, which decreased but not significantly, the performance of boiler equipment during the co-firing process is lighter. There is a decrease in boiler furnace temperature despite changes in load, and boiler equipment performance is still within limits. The average total production cost dropped from 485.324 Rp/Kwh to 484.585 Rp/Kwh with co-firing. During the course of the study, the average Net Plant Heat Rate during the co-firing process fell from 2862.85 kcal/kwh to 2866.35 kcal/kwh.

Abstract

In a ship generally has 2 types of engines, namely the Main Engine (ME) as the driving force of the ship and the Auxiliary Engine (AE) as a supplier of electricity from the power generated by ME. At present the Amrta Jaya 1 Ship utilizes the ME exhaust gas to heat the boiler economizer. Unfortunately this is considered less efficient because the distance is too far between ME and economizer so it takes longer when OHN (one hour notice). To overcome the conventional method, the research was carried out by utilizing the AE exhaust gas which has a distance closer to the economizer. Calculations to determine the heat loss that occurs from the exhaust gas AE to economizer through a copper nickel pipe with a diameter of 1 inch and an insulation thickness of 2 cm, obtained heat loss of 10,539 Watts where the value is still below the maximum heat loss piping system assumed to be 923.52 Watts. So that by utilizing this auxiliary engine exhaust gas, it can be carried out a cost savings of around Rp. 7,875,000.00 when the ship performs an OHN.

Abstract

Haspel or often called cable reel is the item or tool needed to roll the cable. Usually this cable reel is made of wood. However, over time this haspel has changed, especially in the material used, which is made of plastic or polypropyelene (PP) material. This haspel consists of several components including: Flange and barrel reinforced using steel rods. All these components will be assembled and ready for sale. When assembled, the flange components must require a fairly good precision because the material used is plastic, the shrinkage factor plays a very important role when printed with an injection molding machine. At the time of assembling the plastic haspel, there was a failure when the raft product was too tight and there was also a loose raft, this was due to shrinkage in the flange which caused the barrel component to not fit into the router part of the flange. This makes the assembly work a little longer than usual. In this final project, the author takes steps on how to analyze shrinkage defects in plastic materials, especially for polypropylene materials, starting from the injection molding process and then taking product samples with different levels of testing through parameter settings. Different injection times and backpressures will result in different product sizes and shrinkage values. A good melting temperature value is used for polypropylene material with a flange thickness of 6 mm, and a flange diameter of 850 mm ranging from 210°C - 230°C. Shrinkage defects in polypropylene materials certainly exist, and may be greater than polystyrene materials but can be minimized by setting good process parameters. A good and ideal shrinkage value and according to standards occurs at a temperature setting of 220°C backpressure 0.2 Mpa with an injection time of 20 seconds. With constant parameters, starting from the injection speed of 60 mm/s. Injection pressure 18 Mpa and cooling time 250 seconds.
