“…The results showed that the temperature of direct EFB combustion reached 823 o C. Investigations into combustion in a pilot-scale boiler with a capacity of 150 kW using EFB fuel have also been carried out [26]. Research has also been discussed via wet torrefaction at temperatures up to 240°C to remove K, Ca, and Cl from EFB [27][28][29]. So far, fuel production from EFB biomass waste has generally been carried out as briquette fuel.…”

Bio-coke, derived from renewable biomass sources has gained significant interest as a sustainable alternative to conventional fossil fuels. Understanding the influence of pressure and heating on bio-coke properties and combustion characteristics is crucial for optimizing its production and utilization. This study investigates the impact of pressure and heating on the biocoke fuel obtained from empty fruit bunches of biomass waste. Biomass waste, a byproduct of the palm oil industry, offers a potential feedstock for biocoke production, thus addressing waste management and promoting circular economy principles. The experimental approach involved subjecting biomass waste to different pressure levels and heating conditions during biocoke production. The results show that applying pressure during the biocoke production can reduce the water content significantly. The carbon content recorded in biocoke reached 45.87% compared to 43.70% in raw EFB. The proximate and ultimate analysis results show that biocoke fuel shows better results. Thus, biocoke produced using EFB biomass waste is very suitable as an alternative energy to reduce dependence on fossil energy.

“…The transition from conventional energy transformation methods to the use of renewable energies invites us to venture into new ways of generating energy through increasingly cleaner sources [1][2][3]. As is the use of biomass material, which, being a residue of agro-industrial processes, can be used for energy generation as indicated in previous studies [4,5]. What leads to studies to generate new forms of energy transformation, is how biomass presents in its composition a high potential in its volatile material, and its fewer polluting emissions are based on a fuel that will have a high content of H 2 and not based on hydrocarbon chains that increase the carbon footprint in its emissions.…”

Renewable energy sources derived from biomass, such as synthesis gases, represent an opportunity to take advantage of available waste resources and contribute to global energy rationing. This study developed an analysis with computational fluid dynamics (CFD) to estimate the energy behavior of synthesis gases through a turbocharger system. The synthesis gas used to drive the turbocharger turbine was extracted from the gasification of biomass from the Colombian Caribbean. The application of models for rigid body motion, as well as models of momentum, turbulence, energy, and conservation transport of species, suggest that the energy potential available by the turbine ranges from 0.4 kW to 5.2 kW of power generation, concerning mass flow rates entering the simulated system. The main findings of the study were temperature profiles, speed profiles, rotational speed variation, torque, and mechanical power generated in the turbocharger. It is emphasized that the synthesis gas studied presents a good behavior to generate energy through a turbine system of a turbocharger device.

The power generation industry has progressively improved the design of power plants to tackle global climate change. Coal-fired power plants will be cleaner and more efficient with the CFB (Circulating Fluidized Bed) technology in the boiler. CFB boilers have the advantage where the resulting carbon dioxide, SOx, and NOx emissions are significantly reduced. This makes research on CFB boilers widely carried out, especially those using CFD (Computational Fluid Dynamic). This study aims to determine the most appropriate turbulence model using CFD simulations on CFB boilers to analyze the hydrodynamic elements in the boiler against time changes, including the distribution of solid volume fractions, pressure, velocity, and wall shear stress. Three turbulence models were tested as part of the simulation: standard , RNG , and RSM, which were then compared to earlier research. The RNG model produces the closest result to the experimental data, with an error value of 6.24%. Solid volume fraction area is increasingly widespread with values ranging from 0.05 to 0.1 from the furnace’s bottom to a height of 15 m. The high-pressure area further expands at the bottom of the furnace to a height of 15 m, with values ranging from 3 kPa to 10 kPa. The outlet line velocity has increased from 43 m/s to 50 m/s. The wall shear stress increases from 0.75 Pa to 1.1 Pa at the outlet wall.
