Performance analysis of a Kalina cycle for a central receiver solar thermal power plant with direct steam generation

“…On the other hand, the cost of additional equipment like recuperators, separator, mixers and splitters should be compensated by the reduction in the cost from the turbine and the storage system. A more detailed cost study of the KC for geothermal power applications can be found in Campos Rodríguez et al [9] and for waste heat recovery application in Larsen et al [33].…”

Cooling System For Marine Ship Fuel Engines

“…. [14][15] one course of action of a focal cooling framework appears in Figure 2. The ocean water circuit is comprised of high and low suctions, generally on either side of the apparatus space, suction strainers and a few ocean water pumps.…”

Design and optimization of a novel organic Rankine cycle with improved boiling process

“…After these splits, the two rich streams and two of the lean streams are mixed in pairs, and the remaining lean stream is returned to the condenser. This makes it possible to define the outlet conditions for evaporator 1 as saturated vapour for the rich stream and saturated liquid for the lean stream, referred to by Larsen et al [16] as the boiler constraint. The boiler constraint ensures that no temperature change occurs when the streams are mixed after evaporator 1, since the outlet streams are in thermodynamic equilibrium.…”

“…In the OSC the compositions of the rich and lean streams are not changed from the outlet of the separator to the inlet to the boiler. In the Kalina split-cycle configuration investigated by Larsen et al [16] and Nguyen et al [17], the rich stream is split once (creating two streams) and the lean stream is split twice (creating three streams). After these splits, the two rich streams and two of the lean streams are mixed in pairs, and the remaining lean stream is returned to the condenser.…”

“…al. [16] modelled the Kalina split-cycle and found that the Kalina split-cycle with reheat obtained an increase in power output of 11.4 % compared to a reference Kalina cycle without reheat. Nguyen et al [17] used an exergy analysis to compare the Kalina split-cycle and the Kalina cycle, and found that the irreversibilities in the Kalina split-cycle were 2.5-5 % lower than the irreversibilities in the Kalina cycle, primarily due to an improvement of the boiling process.…”
