Analysis of Shell and Tube Heat Exchange Tools as Marine Fuel Oil Heater (MFO) for Unit 4 PLTU Boiler Fuel at PT. PLN (Persero) Belawan Generation Sector

Introduction

The heat exchange device is a crucial component in various industrial processes, including power generation. In the context of PT. PLN (Persero) Belawan Generation Sector, the heat exchange device plays a vital role in heating Marine Fuel Oil (MFO) for Unit 4 PLTU Boiler Fuel. The heat exchanger has been in operation since 1988, and it is essential to analyze its performance to ensure that the system still functions properly and efficiently. This study aims to analyze the performance of the heat exchange device used in Unit 4 PLTU Boiler Fuel at PT. PLN (Persero) Belawan Generation Sector.

Performance Analysis of Heat Exchange Equipment

In this study, the methods used to analyze the performance of heat exchange devices include calculation of effectiveness, decreased pressure, and fouling factors. The comparison is carried out between the design conditions and the actual conditions of the heat exchanger. The calculation results show that effectiveness in actual conditions is 66%, while the design conditions are 67%. Although this difference looks small, but this shows a decrease in effectiveness in the operation of the heat exchanger.

The Importance of Effectiveness in Heat Exchange Devices

Effectiveness is a critical parameter in heat exchange devices, as it determines the ability of the device to transfer heat from one fluid to another. A decrease in effectiveness can lead to a reduction in the overall efficiency of the system, resulting in increased energy consumption and costs. In the context of Unit 4 PLTU Boiler Fuel, a decrease in effectiveness can lead to a reduction in the heating capacity of the MFO, which can impact the overall performance of the boiler.

Pressure Drop in Heat Exchange Devices

The pressure drop in heat exchange devices is another critical parameter that affects the performance of the system. In this study, the decrease in pressure on the Shell side is measured, and the results show that the value of ΔPs for design conditions is 1,177 bar, which is below the permitted limit of 1.7 bar. This shows that the heat exchange device is still within safe limits for operations.

Fouling Factor in Heat Exchange Devices

However, further analysis shows that the fouling factor in actual conditions is greater than the design conditions. This fouling factor can cause a decrease in effectiveness due to a buildup of material that can inhibit fluid flow and reduce effective surface areas for heat exchange. Therefore, routine cleaning and maintenance of heat exchange devices is very important to maintain its performance.

Conclusion and Recommendations

From the results of the analysis, it can be concluded that the heat exchange device is still suitable for use, although there is a decrease in effectiveness. One of the main causes of decreased effectiveness is the fouling factor. Therefore, it is recommended that PT. PLN (Persero) conducts periodic monitoring of the condition of the heat exchanger, including maintenance to reduce fouling. Thus, it is expected that the performance of heat exchangers can be maintained so that the efficiency of marine fuel oil heating can continue to be optimal.

The Importance of Maintenance in Heat Exchange Devices

Maintenance is a critical aspect of heat exchange devices, as it can impact the overall performance of the system. Regular cleaning and maintenance can help to reduce fouling, which can lead to a decrease in effectiveness. In the context of Unit 4 PLTU Boiler Fuel, regular maintenance can help to ensure that the heat exchange device continues to function properly and efficiently.

The Application of This Analysis

The application of this analysis is not only useful for maintaining the performance of heat exchangers but also important for operational sustainability and long-term cost savings in the energy generation sector. By conducting regular analysis and maintenance of heat exchange devices, PT. PLN (Persero) can ensure that the system continues to function properly and efficiently, resulting in cost savings and improved operational sustainability.

Recommendations for Future Studies

Based on the results of this study, several recommendations can be made for future studies. Firstly, further analysis of the fouling factor in heat exchange devices is necessary to understand the causes of fouling and to develop effective strategies for reducing fouling. Secondly, the development of new heat exchange devices that are more efficient and require less maintenance is necessary to improve the overall performance of the system. Finally, the implementation of regular maintenance and monitoring of heat exchange devices is necessary to ensure that the system continues to function properly and efficiently.

Conclusion

In conclusion, this study has analyzed the performance of the heat exchange device used in Unit 4 PLTU Boiler Fuel at PT. PLN (Persero) Belawan Generation Sector. The results show that the heat exchange device is still suitable for use, although there is a decrease in effectiveness. The main cause of decreased effectiveness is the fouling factor, and regular maintenance is necessary to reduce fouling. The application of this analysis is not only useful for maintaining the performance of heat exchangers but also important for operational sustainability and long-term cost savings in the energy generation sector.
