Downloadable (with restrictions)! A single-screw expander with mm diameter screw has been developed. A spiral-tube type evaporator and an aluminum multi-channel parallel type condenser have also been developed with weight of kg and 78 kg, respectively. Based on the development of above components, an ORC (organic Rankine cycle) system prototype was Cited by: integrated rankine bottoming cycle for diesel truck engines This study assessed the feasibility of incorporating a Rankine bottoming cycle into a diesel truck engine. An organic Rankine bottoming cycle (ORBC) previously demonstrated by the US Department of Energy in a heavy-duty, long-haul truck reduced the truck's fuel consumption by about 12%.
A preliminary evaluation has been made of a possibility of bottoming of a conventional Brayton cycle cooperating with the CHP power plant with the organic Rankine cycle installation. Such solution contributes to the possibility of annual operation of that power plant, except of operation only in periods when there is a demand for the : Dariusz Mikielewicz, Jan Wajs, Elżbieta Żmuda.

A system analysis and preliminary design were conducted for an organic Rankine-cycle system to bottom the high-temperature waste heat of an adiabatic diesel engine. The bottoming cycle is a compact package that includes a cylindrical air-cooled condenser-regenerator module and other unique features.

The design of efficient Organic Rankine Cycle (ORC) units for the usage of industrial waste heat at high temperatures requires direct contact evaporators without intermediate thermal oil circuits.
Therefore, the thermal stability of high-temperature working fluids gains importance. In this study, the thermal degradation of hexamethyldisiloxane (MM) is investigated in an electrically heated Cited by: The Organic Rankine Cycle (ORC) is a well known technology since the early ’s.
A large amount of ORC power plants have been built, mainly for geothermal, waste heat recovery and combined heat and power applications.
An ORC has the same system configuration as a steam Rankine cycle but uses organic substances with low boiling points as working fluids. The low boiling point fluids can be vaporized by the low temperature heat sources prior to expansion for work by: The solution proposed in the paper is to use an organic Rankine cycle as bottoming cycle for internal engine CHP.
ORC use the difference between heat produced by the CHP and heat used by consumers. Recent literature reveals that an Organic Rankine Cycle (ORC) system equipped on an ICE might lead to a fuel economy up to %  and an overall e ciency increase up to 12% .
Besides, in reference studies [8,10,11] up to 20% of the waste heat from a heavy-duty diesel engine was recovered.
