Analysis and optimization of a modified Kalina cycle system for low-grade heat utilization

Energy and exergy analysis of entrained bed gasifier/GT/Kalina cycle model for CO2 co-gasification of waste tyre and biochar

“…The heat transferred to the Kalina cycle, and hence the system efficiency, is affected by this occurrence. Similar deductions have also been reported by Hossain et al [77]. The energy and exergy efficiency of the overall system is identical to the Kalina cycle characteristic because the Kalina turbine inlet pressure has no influence on the gasifier or gasifier/GT system.…”

“…The main feature of the Kalina cycle is the use of a water-ammonia mixture, which provides major benefits compared to using a pure working fluid. This is because the saturation temperature of the ammonia-water mixture in a two-phase region is not constant during the heat absorption process at constant pressure [13,14]. This causes the temperature profile of the ammonia-water mixture to be closer to the temperature of the heat source than in the case of a pure working fluid.…”

“…As a result, the exergy destruction rate is significantly lower in the Kalina cycle compared to other waste heat recovery cycles. This is due in large part to the lower temperature difference between the working fluid and the heat source [13,15]. In addition, the turbines of the Kalina cycle are smaller which remarkably appears as an advantage for it.…”
