A compact packing humidifier for the micro humid air turbine cycle: Design method and experimental evaluation

Advances, challenges, and perspectives of biogas cleaning, upgrading, and utilisation

“…Micro humid air turbines, Figure 16, have solved this problem by increasing the mass flow rate of gas in the micro turbine [12,401,402]. In this technology, the heat recovered from the exhaust gas is used to produce hot water [403][404][405][406][407]. Produced hot water is injected in a saturator that humidifies the air entering the combustion chamber to increase the mass flowrate to the turbine, which leads to an increase in power output and efficiency.…”

Maisotsenko Cycle for Heat Recovery in Gas Turbines: A Fundamental Thermodynamic Assessment

“…Xu et al [24] also experimentally evaluated a micro humid air turbine of 100 kW reporting an improvement of ≈22% in electrical efficiency. In another work, Xu et al [25] presented a compact packing humidifier for the micro humid air turbine cycle. Pashchenko et al [26] focused that the thermodynamic efficiency also depends upon the temperature, pressure, and steam-to-methane ratio for a chemically recuperated gas turbine and found that the best heat recuperation rate is up to 0.63 for a high temperature gas turbine while using a steam-to-methane ratio of 3.…”

Parametric Analysis for Varying Packing Materials and Water Temperatures in a Humidifier

“…Results indicated that highest saturation efficiency is found for triangle configuration. Xu et al [7] developed a compact humidifier with novel ceramic foam packing. Packing dimensions were calculated by analytical method based on Merkel theory.…”
