“…Bari [160] reported that carbon dioxide up to 40% will not decrease the engine performance using biogas as a fuel. Biogas can also be used to power engines when mixed with petrol or diesel, and it can also help in pumping water for irrigation [66,[165][166][167]. Cottage/small scale industries use biogas for pumping, milling, and for some other production activities [168].…”

Household Biogas Digesters—A Review

2012

This review is a summary of different aspects of the design and operation of small-scale, household, biogas digesters. It covers different digester designs and materials used for construction, important operating parameters such as pH, temperature, substrate, and loading rate, applications of the biogas, the government policies concerning the use of household digesters, and the social and environmental effects of the digesters. Biogas is a value-added product of anaerobic digestion of organic compounds. Biogas production depends on different factors including: pH, temperature, substrate, loading rate, hydraulic retention time (HRT), C/N ratio, and mixing. Household digesters are cheap, easy to handle, and reduce the amount of organic household waste. The size of these digesters varies between 1 and 150 m 3 . The common designs include fixed dome, floating drum, and plug flow type. Biogas and fertilizer obtained at the end of anaerobic digestion could be used for cooking, lighting, and electricity.

“…l than for the other components discussed above, and so less attention has been applied in this report to descr ure inside the engine cylinders (Jawurek et al, 1987). This results in a reduced methane combustion efficiency, which decreases the maximum power output o n 4,320 m 3 /d (1.14 Mgd) and 192,960 m 3 /d (51 Mgd), tests showed a H 2 S removal efficiency of 98% for 100-1000ppmv H 2 S (Earth Tech et al, 2002).…”

“…In internal combustion engines, the presence of CO 2 reduces the burning velocity of the digester gas (Bari, 1996), and the peak press f the engine (Bari, 1996;Jawurek et al, 1987). Jawurek et al(1987) found that engines operating on digester gas containing more than 30% CO 2 were particularly susceptible to harsh and irregular running, which was alleviated when gasoline was supplied to the internal combustion engine simultaneously with the digester gas.…”

“…Maximum power output was 17% lower with CH 4 than with petrol. Increased CO 2 content of the gas led to further losses, with a 45% loss (compared with petrol) at 41% CO 2 [19]. The presence of carbon dioxide in the biogas reduces the burning velocity which ultimately affects the performance of the engine.…”

Abstract. Turbulent burning velocity is the most important parameter in analyzing premixed combustion simulation of spark ignition engines. It depends on the laminar burning velocity and turbulence intensity in the combustion chamber. The first term can be predicted if one knows fuel composition, physico chemical properties of the fluid. The second term strongly depends on the geometry of the combustion chamber and fluid movement during the combustion process. One cannot suggest a general expression for different cases of engine. Thus, for accuracy modeling, one should determine turbulent burning velocity in the combustion chamber of each case of engine individually. In this study, the turbulent burning velocity is defined by a linear function of laminar burning velocity in which the proportional constant is defined as the turbulent burning velocity coefficient. This coefficient was obtained by analyzing the numerical simulation results and experimental data and this is applied to a concrete case of a Honda Wave motorcycle engine combustion chamber that fueled with compressed biogas. The results showed that the turbulent burning velocity coefficient in this case is around 1.3 when the average engine revolutions is in the range of 3000 rpm to 6000 rpm with biogas containing 80% Methane. We can then predict the effects of different parameters on the performance of the engine fueled with compressed biogas by simulation.
