Introduction

Labuhan Angin Sibolga PLTU is one of the most crucial power plants in North Sumatra, with a capacity of 115 MW. This power plant plays a vital role in meeting the electricity needs of the region and maintaining the stability of the electrical system. In the world of electricity industry, the efficiency of a power plant is a key benchmark for assessing its performance. A high efficiency value indicates the ability of generators to produce electricity with minimal energy losses.

The Importance of Efficiency in Power Plants

Efficiency is a critical factor in the performance of a power plant. It reflects the ability of generators to produce electricity with minimal energy losses. In the case of Labuhan Angin Sibolga PLTU, the efficiency of the plant is affected by the performance of the prime mover, which functions to move the generator. This process requires in-depth analysis, one of which is through the Heat Losses method for boilers. This method focuses on calculating boiler efficiency by analyzing energy losses that occur during the combustion process.

The Heat Losses Method

The Heat Losses method is a widely used technique for calculating boiler efficiency. It involves analyzing energy losses that occur during the combustion process. The method takes into account various factors, including the loss of exhaust gas heat, wet loss, loss of burning hydrogen, and loss of carbon not burned. By analyzing these factors, the method provides a comprehensive understanding of the energy losses that occur in the boiler.

Methodology

In this study, measurements were carried out manually, with special emphasis on the calculation of efficiency in the boiler and turbine heat value. The results of this calculation are crucial in determining how effective the movement is starting to work, as well as to calculate the overall efficiency of the Labuhan Angin PLTU. Data obtained during the study showed significant results, including the loss of exhaust gas heat of 417.25 BTU/lb, wet loss of 208.17 BTU/lb, loss of burning hydrogen 223.54 BTU/lb, and loss of carbon not burned 15.3 BTU/LB.

Analysis of Results

From the data obtained, it can be seen that the biggest loss occurs in the heat of the exhaust gas and wet losses. These losses indicate that there is potential to increase the efficiency of the generator by optimizing the combustion process and temperature regulation in the boiler. For example, the reduction in the loss of exhaust gas can be achieved by improving the isolation system and increasing a more perfect combustion process.

Boiler Efficiency

Boiler efficiency of 81.48% is an indication that there is still space for improvement. By carrying out proper improvement and maintenance steps, not only the efficiency of the boiler can be increased, but also the overall efficiency of the Labuhan Angin PLTU. This of course has an impact on reducing operational costs and increasing the competitiveness of PLTU in meeting the energy needs that continue to increase in North Sumatra.

Conclusion

Through this research, it is essential for PLTU management to understand the value of efficiency and its influence on overall performance. By knowing where the loss occurs and how much value is, strategic steps can be taken to increase efficiency and in the end, the competitiveness of the PLTU in the Energy Market. This knowledge is not only beneficial for current operations but also as a basis for future planning in the development and improvement of the electrical system in Indonesia.

Recommendations

Based on the findings of this study, the following recommendations are made:

Improve the isolation system to reduce the loss of exhaust gas heat.
Increase the combustion process to reduce wet loss.
Conduct regular maintenance to ensure optimal performance of the boiler.
