Introduction

In the pursuit of sustainable and renewable energy sources, biomass-based power plants have emerged as a promising alternative to traditional fossil fuels. However, designing an efficient biomass-based power plant requires a thorough understanding of the heat value and exergy of the fuel to be used. This article aims to discuss the energy analysis and exergy of several types of biomass fuels, namely oil palm shells, empty palm oil bunches (TKKS), fiber (fiber) oil palm fruit, eucalyptus bark, and candlenut leather.

The Importance of Energy Analysis and Exergy in Biomass-Based Power Plants

Energy analysis and exergy are crucial in determining the effectiveness and efficiency of a biomass-based power plant. Energy analysis helps in determining the heat value of the fuel, which is essential in designing an efficient generator system. Exergy analysis, on the other hand, determines the quality of energy that can be obtained from the fuel, which is vital in improving the performance of power plants.

Testing Methodology

The biomass fuel tested was carried out through a device called the calorimeter bomb, which serves to determine the heat value of the fuel. The results of this test will show how much energy can be produced from each type of biomass. The heat value is usually expressed in two forms, namely the value of the gross heat (HHV) and the net heat value (LHV).

Calorimeter Bomb: A Device for Determining Heat Value

The calorimeter bomb is a device used to determine the heat value of biomass fuels. It works by burning a sample of the fuel and measuring the amount of heat released. The heat value is then calculated based on the amount of heat released and the mass of the fuel sample.

Data Results and Analysis

Based on the results of the data analysis, the palm oil shell shows the highest heat value, with the LHV of 26,465.96 kJ/kg and exergy of 11,683,592 kJ/kg. That is, oil palm shells not only have high energy content but are also able to use the energy efficiently.

Palm Oil Shells: A High-Energy Content Biomass Fuel

Palm oil shells have been found to have a high heat value, making them an attractive option for biomass-based power plants. Their high energy content and efficient energy use make them an ideal choice for power generation.

Conversely, eucalyptus bark records the highest exergy value of 12,755,678 kJ/kg with LHV of 15,730.64 kJ/kg. This shows that eucalyptus bark has high energy potential and can be used well in the application of energy generation. Thus, from this analysis it can be seen that although oil palm shells have a high heat value, eucalyptus bark has better energy quality in terms of exergy.

Eucalyptus Bark: A High-Energy Potential Biomass Fuel

Eucalyptus bark has been found to have a high exergy value, making it an attractive option for biomass-based power plants. Its high energy potential and efficient energy use make it an ideal choice for power generation.

Fuel Composition and Energy Needs

Further analysis is done by mixing various types of biomass. For example, a mixture of fuel consisting of 20% of oil palm shells, 40% of oil palm fruit fibers, 10% TKKS, 15% candlenut skin, and 15% of eucalyptus bark, needed to meet the needs of multifuel boiler plants of 25.654 kg/hour. This composition is chosen based on the energy potential and exergy of each type of fuel, which can produce a more efficient and environmentally friendly combustion process.

Optimal Fuel Composition for Biomass-Based Power Plants

The optimal fuel composition for biomass-based power plants is a critical factor in determining the efficiency and effectiveness of the power plant. By mixing various types of biomass, optimal fuel can be obtained for the energy needs of power plants, which not only efficient but also support environmental sustainability.

Conclusion

Energy analysis and exergy of biomass fuel is very important to increase the efficiency and effectiveness of biomass-based power plants. The results of the analysis show that the palm oil shell has the highest heat value, while eucalyptus bark offers better energy quality in terms of exergy. By mixing various types of biomass, optimal fuel can be obtained for the energy needs of power plants, which not only efficient but also support environmental sustainability. Through this research, a deeper understanding of the energy potential of biomass fuels can make a positive contribution in the development of renewable energy in the future.
