Refined augmented Lagrange Hopfield network–based Lagrange relaxation for hydrothermal scheduling
This paper proposes a refined augmented Lagrange Hopfield network–based Lagrange relaxation (ALHN–LR) for solving short term hydrothermal scheduling (HTS) problem with pumped–storage hydro units. ALHN–LR consists of improved Lagrange relaxation (ILR) and augmented Lagrange Hopfield network (ALHN). For solving the HTS problem, the proposed method applies enhanced ILR for finding thermal unit ...

Case Study - Helmsley Open Air Pool
Helmsley Open Air Pool is operated by a registered charity – the Feversham Memorial Trust – and opens from June to September each summer. The 1930s pool is 25m in length and 10m wide. The existing heating system comprised an oil boiler working in tandem with an electric heat exchanger. During the 2007 season the oil boiler broke down and was in need of replacement. To keep the pool ...

Performance of microbial fuel cells on removal of metronidazole
The microbial fuel cells (MFCs) are the focus of extensive investigation as one of the promising technologies for renewable energy generation and wastewater treatment. Two-chambered MFCs were designed to investigate the removal of metronidazole and to quantify the effect of antibiotic on the efficacy of energy generation. Using 1,000 mg glucose L−1 containing different concentrations of ...

Making biodiesel blends fuel is simple
Biodiesel is made in the process of transesterification of vegetable oil by methanol, although sometimes ethanol or isopropyl alcohol are used instead. The ration is approximately 200 kg of methanol per 1 ton of oil (plus potassium or sodium hydroxide). Process temperature is approximately 60°С, no pressure increase is required. After the transesterification reaction, the content of ...

Algae biofuel can cut CO2 emissions by at least 50% petroleum fuels
PRESTON, Minn., Sept. 20 (UPI) -- Algae-derived biofuels can reduce the life cycle of carbon dioxide emissions by at least 50 percent compared to petroleum fuels, a U.S. university study found. The peer-review study -- the first to analyze real-world data from an existing algae-to-energy demonstration scale farm -- indicates the environmental and energy benefits of algae biofuel are at least on ...

EPA provides more time to comply with air standards for oil, gas storage tanks
The Environmental Protection Agency will give industry additional time to install air pollution controls on storage tanks that are used during the production and transmission of oil and natural gas, according to a final rule released Aug. 5. The agency now will phase in the deadlines to control volatile organic compounds through April 15, 2015, rather than requiring compliance by Oct. 15, 2013, ...

Turning waste into power
Economic, social and environmental factors dictate the necessity to manage waste to a new level. Wastewater plants, landfills, farms and food plants are all the owners of biomass that can be digested to produce biogas and turned into power. Biogas can be burned directly in boilers for heat recovery and used for manufacturing, heating or cooling; this is the simplest method of direct biogas ...

Domestic fuel price and the Nigerian macroeconomy
This study examined empirically a one–to–one nexus between domestic fuel price and various macroeconomic variables in Nigeria for the period spanning 1986 to 2011. The study adopted both a vector auto–regressive (VAR) and a vector error correction (VEC) models for appropriate analysis. For pairs of variables that are integrated of the same order but not co–integrated, the VAR model revealed that ...

Gently does it takes you further
Drivers of petrol and diesel cars are usually aware that driving at high speed, harsh acceleration and hard braking all contribute to lowering their fuel economy. Scientists can readily explain in terms of the thermodynamics of the internal combustion engine why driving such a car more smoothly and at gentler speeds will increase significantly the distance that might be travelled on a single tank ...

Use of biogas for cogeneration of heat and electricity for local application: performance evaluation of an engine power generator and a sludge thermal dryer
A small unit of cogeneration of energy and heat was tested at the Centre for Research and Training on Sanitation UFMG/COPASA – CePTS, located at the Arrudas Sewage Treatment Plant, in Belo Horizonte, Minas Gerais, Brazil. The unit consisted of an engine power generator adapted to run on biogas, a thermal dryer prototype and other peripherals (compressor, biogas storage tank, air blower, ...

Exergetic and exergo–economic analysis of a turboprop engine: a case study for CT7–9C
The turboprop engine has played an important role in short haul commuter and military transport aircraft where high speed is not critical. It may provide the aviation sector with one of the most significant means of achieving reduced operating costs through reductions in fuel consumption. This paper deals with exergo–economic analysis of a modern turboprop engine (CT7–9C) with a free power ...

Commercialising Aviation Biofuels
Aviation currently produces 2 per cent of the world's greenhouse gas emissions. To tackle this issue the industry has set itself a target to cut emissions by 50 per cent by 2050, compared to 2005 levels. The production and use of sustainable quantities of aviation biofuels is key to meeting industry's ambitious carbon reduction targets and British Airways (BA) wants to pioneer the move towards ...

Performance of a direct diesel engine using aviation fuels blended with biodiesel
In this study, jet fuel (JF) and railroad fuel (D2) with SME blends (5%, 20%, 50%) were used in a four–cylinder, naturally aspirated, direct (DI) diesel engine. The engine was operated under full load and tested at various speeds to determine the engine's performance and exhaust emission characteristics. The experimental results show that as the SME ratio of the fuels increases, the break ...

Gaseous release in LiNH2–MgH2 systems
Hydrogen is considered a safe and clean alternative to fossil fuels. Hydrogen storage is currently obtained by compressing the gas at high pressure. Researchers are currently attempting to tackle safety and energy density issues by locking hydrogen into solids, packing large quantities into small volumes. However, most of the known solids (i.e. intermetallics) show very low gravimetric density, ...
