ORGANIC RANKINE CYCLE ASSOCIATED WITH AN ABSORPTION CHILLER FOR BIOMASS APPLICATIONS

Exergy Analysis of a Novel Combined System Consisting of a Gas Turbine, an Organic Rankine Cycle and an Absorption Chiller to Produce Power, Heat and Cold

The current work investigates the exergy analysis of a new system to generate power, heat, and refrigeration. In the proposed system, the heat loss of a gas turbine (GT) is first recovered by a Heat Recovery Steam Generator (HRSD), then by an Organic Rankine Cycle (ORC) to generate warm water and additional power, respectively. In the ORC, reheating is used to increase the output power, the req...

“organic Rankine Cycle (orc) in Biomass Plants: an Overview on Different Applications“

The ORC technology in cogenerative systems has by now reached a level of full maturity in biomass applications. In Europe, there are over 120 plants in operation with sizes between 0.2 and 2.5 MW electric. ORC systems are very flexible and can be used in different applications like district heating systems, pellet production factories, sawmills and tri-generation systems with absorption chiller...

An Alaska case study: Organic Rankine cycle technology

Adaptive PI Control of an Organic Rankine Cycle Power Plant

In this paper a PI based adaptive control system is developed to control an organic Rankine cycle power plant. In particular, the control of the turbine speed during the transient between the normal operation mode of the system (connected to the grid) and the islandmode (connected to a stand-alone load) is of main concern. A control algorithm suitable for the implementation on a programmable lo...

Thermodynamic performance of new thermofluidic feed pumps for Organic Rankine Cycle applications

This study develops thermofluidic pump technology that is powered by heat, rather than by electrical or mechanical power. The objective is to improve the performance of heat-recovery by Organic Rankine Cycles, by using a recently-proposed thermofluidic pump. The thermofluidic pump promises low-cost, high-reliability, and, since it does not consume any of the power produced by the expander, impr...
