Biodiesel has the potential to replace the conventional diesel fuel, thus the increasing interest and research in the use of biodiesel fuels for transport applications to improve the emisions. In this work, the spray characteristics of diesel with hydrogenated catalytic biodiesel (HCB) fuel blends were investigated in a constant volume combustion chamber to provide an accessible tool to predict spray...
The operation characteristics of a 10 kW organic Rankine cycle using R245fa and adapting stand alone and grid connect operation strategies have been investigated. The heat input increases from 34.18 to 87.40 kW for stand alone and from 53.37 to 112.76 kW for grid connect operation strategy, while degree of superheating and subcooling are fixed at 9.5 ± 0.5 and 7 ± 0.5 °C, respectively. The detailed...
Pyrolysis characteristic of hydrogenated palm oil (HPO) was analyzed using TG, TG-FTIR-MS and Py-GC-MS. Bio-fuel oil (BFO) was obtained using catalytic cracking method. The BFO was analyzed by FTIR, 1H NMR, 13C NMR, GC-MS and ESI FT-ICR MS to provide complementary and comprehensive adequate information. TG-DTG results showed that the HPO pyrolysis was different with other plant oil. It was clear that...
The effect of additives (NH4H2PO4, CaCO3 and CaO) on biomass carbonization was studied in the current paper, including residual K and Na in chars, SO2 and NO emission of different chars during combustion. Experiment was carried on a tube furnace system. The results show that, CaO and NH4H2PO4 reduce the alkali content of chars to different degree. Three additives inhibit SO2 emission from raw and...
The influence of ammonium dihydrogen phosphate (NH4H2PO4) on the potassium (K) retention ability in the ash phase and the ash melting characteristics during biomass combustion was investigated. Experiments were performed in a tube furnace experimental system and an ash melting point detector. The results show that the addition of NH4H2PO4 will increase the potassium retention ability in the ash phase...
A novel GAHP-TSU (gravity-assisted heat-pipe thermal storage unit) is presented, in which the composite granular solid–liquid PCM (phase-change material) is piled up as the porous-medium layer. The composite PCM, which melts over a temperature range of 200–250 °C, is composed of a mixed metal salt and inorganic bentonite. Naphthalene is presented as the phase-change heat-transfer medium of the GAHP-TSU...
