Mainly due to its long history, sucker-rod pumping is a very popular means of artificial lift all over the world, roughly two-thirds of the producing oil wells are on this type of lift. To maximize profits from these wells in the ever-changing economic situation with rising costs of electric power, installation designs must ensure optimum conditions. In the paper, basic considerations on ensuri...

Ceramic tile manufacturing is a highly energy-intensive process. Concerns about carbon emissions and energy costs make management crucial for this sector, which holds leading role in Italian industry. The paper discusses the energetic environmental performance of cogeneration (CHP) ceramic industry, where prime mover exhaust heat supplied to spray-dryer system, contributing satisfaction thermal...

Non-electrified regional railway lines with typically employed diesel-electric multiple units require alternative propulsion systems to meet increasingly strict emissions regulations. With the aim identify an optimal conventional diesel traction, this paper presents a model-based assessment of hydrogen-powered internal combustion engine or fuel cells as prime mover, combined different energy st...

A new generation of small scale (less than 20 MWe) biomass fueled, power plants are being developed based on a gas turbine (Brayton cycle) prime mover. These power plants are expected to increase the efficiency and lower the cost of generating power from fuels such as wood. The new power plants are also expected to economically utilize annual plant growth materials (such as rice hulls, cotton g...

Energy is the prime mover of economic growth. Availability of energy with required quality of supply is not only key to sustainable development, but also the commercial energy has a direct impact and influence on the quality of service in the fields of education, health and, in fact, even food security. Inadequacy of energy supply would obviously affect very adversely these vital and essential ...

Fuel cell power for locomotives combines the environmental benefits of a catenaryelectric locomotive with the higher overall energy efficiency and lower infrastructure costs of a diesel-electric. A North American consortium, a public-private partnership, is developing a prototype hydrogen-fueled fuel cell-battery hybrid switcher locomotive for urban and military-base rail applications. Switcher...
