“…The brake thermal efficiency of the producer gas engine at each CR was lower than that of the diesel engine. Hence, the reduction in efficiency occurred due to characteristics of the fuel, lower compression ratio and volumetric efficiency [12]. The brake thermal efficiency tended to increase with engine load and speed.…”

“…At CR of 10.5, Shivapuji and Dasappa [11] who investigated combustion characteristics of internal combustion engines operated on producer gas reported a de-rating of only about 19% for a 76 kW turbocharged SI engine. Raman and Ram [12] reported test results of producer gas on an SI engine, compared to natural gas operation at a CR of 12:1. The maximum overall efficiency was 21% at 85% of full load, while maximum power output was reduced by 12.4%.…”

“…From the operation conditions of the system is apparent, that the internal combustion engine equipped with a dual fuel system should deliver the required effective torque and adequate effective power (for given engine speed 0 r  ). For assurance that the whole combustion process in the engine cylinder proceeds smoothly, evenly and completely some basic conditions should be satisfied [3,4,8].…”

11# Summary. Internal combustion engines are fuelled mostly with liquid fuels (gasoline, diesel). Nowadays the gaseous fuels are applied as driving fuel of combustion engines. In case of spark ignition engines the liquid fuel (petrol) can be totally replaced by the gas fuels. This possibility in case of compression engines is essentially restricted through the higher self-ignition temperatures of the combustible gases in comparison to classical diesel oil. Solution if this problem can be achieved by using of the dual fuel system, where for ignition of the prepared fuel gas -air mixture a specified amount of the liquid fuel (diesel oil) should be additionally injected into the combustion chamber. For assurance that the combustion process proceeds without mistakes and completely, some basic conditions should be satisfied. In the frame of this work, three main aspects of this problem are taken into account: a. filling efficiency of the engine, b. stoichiometry of the combustion, c. performance of mechanical parameters (torque, power). A complex analysis of these conditions has been done and some achieved important results are presented in the paper.

Low‐tar, highly burnable gas production from the gasification of pelletized palm empty fruit bunch

Gasification is an attractive method to convert lignocellulosic biomass into a combustible gas mixture for electricity and power generation. To control the tar concentration in the produced gas to be within the allowable limit of downstream applications, it is important for a gasification system to be integrated with a tar removal process. In this study, an integrated gasification system consisting of a downdraft gasifier and a secondary catalytic tar‐cracking reactor was designed and tested for the gasification of pelletized oil palm empty fruit bunch. To further purify the producer gas, the system was also integrated with a cyclone, a water scrubber, and a carbon‐bed filter. Biomass was fed at a rate of 5 kg/h, while the air equivalence ratio (ER) and the gasification temperature were set at 0.1 and 800°C, respectively. In total, 5 kg of the specially developed low‐cost Fe/activated carbons (AC) catalyst was used in the hot gas catalytic tar‐cracking reactor. Results indicate that our integrated gasification system was able to produce a clean burnable gas with a lower heating value (LHV) of 9.05 MJ/Nm3, carbon conversion efficiency (CCE) of 79.4%, cold gas efficiency (CGE) of 89.9%, and H2 and CH4 concentrations of 29.5% and 10.3%, respectively. The final outlet gas was found to only contain 32.5 mg/Nm3 of tar, thus making it suitable for internal combustion engine (ICE) application.
