The aim of the present study was to investigate effects application hydrotreated vegetable oil (HVO) mixed with pure duck fat (F100) as fuel, replacing conventional fossil diesel fuel (D100). tests were performed using a four-stroke direct injection CI engine engine. Six samples used: D100, HVO100, F100, well three HVO–fat mixtures F25, F50, and F75. To further main characteristics combustion, ...

Large scale power production benefits from the high efficiency of gas-steam combined cycles. In the lower power range, fuel cells are a good candidate to combine with gas turbines. Such systems can achieve efficiencies exceeding 60%. High temperature Solid Oxide Fuel Cells (SOFC) offer good opportunities for this coupling. In this paper, a systematic method to select a design according to user ...

Great efforts have been spent to reduce the greenhouse gas (GHG) emissions and improve the efficiency of the Integrated Gasification Combined Cycle (IGCC). This study focuses on investigating two approaches to achieve these goals. First, replace the traditional subcritical Rankine steam cycle of the overall plant with a supercritical steam cycle. Second, add different amounts of biomass as feed...

Surrogate fuels for hydrothermal liquefaction (HTL) algae biocrude depicting its nitrogen (N) and sulphur (S) content were simulated in this study tested a multi-cylinder diesel engine. The influence of N S presence the fuel on combustion behaviour emissions profile was investigated. To our knowledge, S-containing reference to HTL biocrude, have not been reported an internal engine literature, ...

Pertumbuhan infrastruktur, khususnya di sektor energi, semakin cepat setiap hari. Hal ini dikarenakan penggunaan kebutuhan tersebut meningkat dari hari ke Ironisnya, berbanding terbalik dengan pasokan energi yang tersedia Indonesia. Masih banyak kota terutama Indonesia bagian timur masih belum teraliri listrik. Salah satu bahan bakar menjadi kendala terbesar bagi wilayah timur, dan Papua, sumbe...

In 2018, a 5/15 kW DC reversible solid oxide cell system was developed and successfully operated by Forschungszentrum Jülich. Based on the knowledge gained with this first system, an optimized in power class of 10/40 AC afterwards 2019 that uses well-established Integrated Module. This module consists four 20-layer sub-stacks, two heat exchangers five heating plates. It represents main componen...

Currently, in the world are trying to substitute fossil energy for renewable energy. One of is biomass Biomass a natural resource derived from biological nature. palm shells has been successfully used by Tembilahan PLTU as an effort coal. The results technical evaluation and monitoring show operating parameters within normal limits. Palm known have lower sulfur content than coal so that emissio...

Burning experiments are analyzed for 59 successfully ignited tests using a gas burner (BRE) to emulate the steady burning of 25 mm diameter flat surface materials. More than half resulted in long burns at least 2 and as 5 min. Mixtures ethylene nitrogen allow 23.6 47.2 kJ/g heats combustion (LHV). Nominal ambient conditions range from 40% 21% oxygen pressures 1 about 0.56 bar. NASA human habita...

Use of biomass in domestic cookstoves leads to the release oxides nitrogen (NOx), nitric oxide (NO), dioxide (NO2), carbon monoxide (CO) and hydrocarbons CxHx that can be detrimental health public environment. Attainment complete combustion is best strategy for mitigating these emissions. This study sought experimentally determine effects secondary air injection on emission profiles NOx (NO & N...
