Combustion characteristics of a diesel engine operated with diesel and burning oil of biomass

In this study, burning oil of biomass (BOB) was derived from biomass corncob tar by distillation. The fuel BOB1 was extracted from biomass corncob tar by distilling temperature range from 110 to 220 °C, the fuel BOB2 was extracted from biomass corn tar by distilling temperature over 220 °C. This paper presents that the results in the physical characteristic of BOB as an alternative fuel and a comparative control experiences in unmodified diesel engine. Engine power performance, fuel consumption and emissions (CO₂, CO, HC and NO) have been studied. There was no significant difference in performance between diesel fuel and mixed fuel. The mixed fuel operation produced low fuel consumption at the various loading. Mixed fuel 1 (mixed 10% BOB1 with diesel by volume) and mixed fuel 2 (mixed 10% BOB2 with diesel by volume) with 11.7 and 6.6% oil-economizing rate, had better oil-economizing compare to diesel fuel respectively. The mixed fuel 1 and mixed fuel 2 showed significant improvement at CO₂ emissions.     

Modelling of electrical energy recovery from urban solid waste system: The case of Dhaka city

This paper presents a system dynamics computer model to predict population growth, solid waste production, electricity generation from solid waste and percentage of total electricity demand supplied from the solid waste of Dhaka, Bangladesh. Simulated solid waste generation in Dhaka agrees well with values reported by the Dhaka City Corporation. Simulated results show that population, solid waste generation and electricity generation potential from solid waste all increase with time, but percentage of total electricity demand supplied from solid waste decreases with time. However, MSW could still supply a significant portion of the electricity demand of Dhaka. Adoption of policy for electricity recovery from urban solid waste should be dictated by the economic adoption of the technology for electricity generation from the waste and the environmental implications. The model can be used for analysing electrical energy recovery from urban solid waste management.
