Abstract

Biomass has several advantages, especially as it is renewable in nature. The low energy content owned by biomass requires the use of effective techniques, such as gasification.  This research was to determine the rate of heat transfer that occurs in the burning of fuel in the combustion chamber fluidized types. The benefit of this research is to identify the heat loss in biomass combustion system. The fuels used in this study are wood-planed chips, branches of dry wood and areca nut husk. The size of fuel was 2 to 3 mm. The fuel was weighed to 2 kgs for one testing/biomass. The combustion duration was 50 seconds. The heat loss in biomass combustors with wood-planed chips occurred in 30 seconds at Tf 724oC and TW 203 oC, the heat loss was 26813.33 W/m. The heat loss in the combustion chamber with biomass wood-planed chips in 15 seconds at Tf-average 334 oC and Tw 44 oC, the heat loss was 2947.03 W/m. The heat loss in biomass combustors with branches of dry wood in 30 seconds at Tf 713 oC and Tw 201 oC, the heat loss was 26350.15 W/m. The heat loss in the combustion chamber with branches of dry wood biomass in 20 seconds at Tf-average 286 oC and Tw 42 oC, the heat loss was 2479.57 W/m. The heat loss in biomass combustors with areca nut husk occurred in 20 seconds at Tf 515 oC and Tw 137 oC, the heat loss was 19453.82 W/m. The heat loss in the combustion chamber with areca nut husk biomass occurred in 15 seconds at Tf- average 118 oC and Tw 39 oC, the heat loss was 802.81 W/m.

Abstract

Calcium carbide residue is an unutilized by-product. It contains high calcium and can be used to produce cementitious. The variation of Calcium carbide residue used is 0%, 5%, and 15%. This study focused on the reduction of the cement used and lightweight bricks resistance toward the fire condition. Moreover, the tests were carried out by examining the compressive strength before and after lightweight bricks burned, X-ray fluorescence (XRF), Scanning Electron Microscope (SEM), and Fourier-Transform Infrared Spectroscopy (FTIR). The result showed a decrease of compressive strength on 10% and 15% carbide variation. At the combustion temperature of 250 °C, micro-cracking occurred at 0% and 5% carbide specimens, while not only cracking but also spalling and crazing were at the specimens with 10% carbide. The 5% variation of calcium carbide residue can increase the compressive strength and endurance at 250 °C. At the higher temperature, the compressive strength was decreased, and the material was damaged. IR-spectroscopy test results showed that 5% carbide composition achieved the highest compressive strength because the amount of H2O2 used reacts with CaO.

Abstract

Waste glass constitutes significant landfill waste, leading to environmental concerns. Considering its chemical composition, glass powder contains 50% to 60% silica, making it suitable for construction materials. Consequently, this community service initiative introduced waste glass as a building material, serving as a partial substitute for sand in construction products. In addition, the activity involved teaching partners how to create castings/road gates utilizing waste glass. The target partners in this activity were productive business groups engaged in selling wind holes, well rings, rosters, and similar products. The approach applied involved socialization and hands-on practices at the partner's premises. The program's success was obtained through interviews and product compressive strength tests with the partners. The outcomes demonstrate the partners' keen interest in the activity, their understanding of the benefits of utilizing waste glass as a partial sand replacement, and their ability to create products. Notably, the compressive strength of the products created with the partners ranged from 24.72 MPa to 30.84 MPa, aligning with the SNI 03-2442-1991 standard for road curbs (30 MPa). The activity positively impacted the partners, enhancing their business prospects and contributing to environmental sustainability. The training helps in enhancing the partners' skills and capabilities.

Abstract

Biomass waste from palm oil mill processing in Indonesia, especially on the island of Sumatra one of which is Aceh Province, is currently quite abundant and has not been managed optimally. This biomass waste can be converted into solid energy, which can be used as energy for biomass power plants. The aim of this research is specifically to convert biomass waste into solid energy. This research applies Simultaneous compression with heating as a fuel production method. The biomass waste used as solid fuel production material is empty palm oil bunches. The results of the fuel production process based on palm oil biomass waste show that the energy value reaches 26.80 MJ/kg. The carbon content in the produced fuel reaches 47.56%, with a low ash content of 6.70%. Calculations of the density of biomass-based fuel before and after production show an average of 1.42 grams/cm3. The results of tests carried out on fuel produced using palm oil biomass waste show high energy potential that can be used to reduce dependence on the use of coal.

Abstract

This research evaluates the performance and combustion emissions of boilers using solid palm oil waste fuel. Experiments were conducted by measuring operational parameters such as temperature, pressure and thermal efficiency at different load variations. Analysis of the combustion of three types of oil palm biomass shows that oil palm shells consistently reach peak temperatures faster and higher (800-900°C) than empty palm fruit bunches and palm fronds (600-700°C). This combustion pattern indicates that palm kernel shells are more suitable for rapid energy release applications. In contrast, empty palm fruit bunches and palm fronds are ideal for steady and sustained combustion. In addition, the emissions analysis identifies exhaust gas components including CO, CO₂, SO₂ and NOₓ. The results show that palm oil solid fuel has the potential to be an efficient alternative fuel with thermal efficiencies of up to 80%. However, there is still a need to consider exhaust emissions due to increased CO and NOₓ compared to conventional fossil fuels. This study provides insight into the use of palm oil waste for renewable energy, although further optimisation is required to reduce the environmental impact.
