ERDA's companion government group, the Environmental Proportion­ ment Administration, cautioned the new energy source may be danger­ ous to the environment. A spokesman said emissions from the combustion contained unknown compounds which are likely to be dirty and toxic. Besides, the fuel contains bacteria which are known to reproduce. In reply, ERDA countered that many components of the new fu...

Abstract Landfills are urban stocks and resource reservoirs for potential energy recovery. The purpose of this study is to evaluate the amount that could be recovered from aged waste (around 5–20 yr old) landfills. Investigations were conducted on physical chemical properties refuse-derived fuel (RDF) prepared landfill (RLW) in Andhra Pradesh, India. Waste characterization studies include deter...

Solid waste management is challenging in Phnom Penh city, Capital of Cambodia. The only one formal treatment taken is the final disposal of mixed waste into an open dumpsite. The current study analyses the physical and chemical characteristics of municipal solid waste disposed of in the dumpsite to assess their suitable handling methods. The current study found that the major compositions of wa...

Fuel cycle cost of a fast reactor is expected to play an important role of compensating for higher capital cost of a Fast Reactor and keeping the unit energy cost competitive. PFBR fuel cycle cost has been worked out by a committee constituted for the purpose. The cost has been worked out for a peak fuel burn-up of 1,00,000 MWd/t. The basic components of the PFBR fuel cycle are fabrication cost...

barrels of oil equivalent (boe) The total energy content of a non-petroleum-based product or fuel in GJ divided by 5.904 6.115 GJ/boe. biodiesel The methyl or ethyl esters of transesterified triglycerides (lipids, fats, cooking greases) from biomass. biofuel A solid, gaseous, or liquid fuel produced from biomass. biogas A medium-energy-content gaseous fuel, generally containing 40 to 80 volume ...

most of electricity is generated by thermal power plants in iran. shahid rajaee thermal power plant consists of four 250mw natural gas and fuel oil burning units that is located at 100 km west off tehran. as a result of fuel oil burning in winter time, boilers air heaters are washed and cleaned frequently. the wastewater originating from air heater washing contains suspended solids and differen...

The United States is now re-assessing its nuclear waste disposal policy and re-evaluating the option of moving away from the current once-through open fuel cycle to a closed fuel cycle. In a closed fuel cycle, used fuels will be reprocessed and useful components such as uranium or transuranics will be recovered for reuse (e.g., Bodansky, 2006). During this process, a variety of waste streams wi...

The disposal of hazardous wastes creates major economic and environmental problems for both developed and developing nations. One productive use of hazardous wastes is to blend them into fuel, which mitigates damage to the environment by recycling waste into fuel and reducing fossil-fuel consumption. Operations personnel face a daunting task of efficiently blending hazardous waste into fuel, wh...

The aim of this work was to study the combustion, performance, and emission characteristics of a 5.5 kW four-stroke single-cylinder water-cooled direct-injection diesel engine operated with blends of biodiesel-like fuel (BLF15, BLF20 & BLF25) obtained from a 50:50 mixture of transesterified waste transformer oil (TWTO) and waste canola oil methyl esters (WCOME) with petroleum diesel. The mixtur...
