Proposal of humid air turbine cycle incorporated with absorption heat transformer

Abstract

A detailed graphical exergy study based on the energy‐utilization diagram (EUD) is applied to humid air turbine (HAT) cycle incorporated with a modified two‐stage absorption heat transformer (TAHT). Employing the sensible and latent heat exchange modes in this TAHT and then introducing to the HAT cycle have clarified that this method can intensively recover the waste heat of HAT cycle and improve the system performance. Compared to a conventional HAT cycle, the overall cycle efficiency can be increased by 2 per cent points and the specific work can be increased by 7.3 per cent.

Recycling waste heat energy using vapour absorption heat transformers: A review

“…Ishida and Ji [9,43] proposed the use of multi-compartment absorbers and generators (see Section 2.3) in order to minimise exergy losses and hence irreversibility within heat transformers. Scott et al [44,45] developed an open cycle using such a multicompartment absorber and generator.…”

“…Ishida and Ji [43] proposed the inclusion of a DSHT into a humid air turbine (HAT) system. The DSHT used both multicompartment absorbers and generators to minimise exergy losses.…”

Low grade heat recovery system for woodfuel cogeneration plant using water vapour regeneration

“…The absorption heat pumps and transformers are applied in different technologies of heat and electricity generation [4][5][6][7][8] including fuel cell technology [9] and refrigeration system [10]. Lund et al, [11] note that waste heat of lower temperature could be utilised for space heating and, naturally, the heat pump technology should be used.…”

Performance and Exergy Analysis of Open Absorption Heat Pump

“…As a rich hydrogen fuel, nature gas combustion may generate a lot of vapor which lead to more latent heat. Waste heat especially latent heat recovery from flue gas is useful for improving nature gas utilization efficiency [1][2] . Furthermore, the condensation water which produced in the process of latent heat recovery can be reused, which may save water resource to some extent.…”
