Energetical, exergetical and economical optimization analysis of combined power generation system of gas turbine and Stirling engine

A techno-enviro-economic assessment of a biomass fuelled micro-CCHP driven by a hybrid Stirling and ORC engine

“…In principle, the electrical efficiency of a thermal power plant can be enhanced by utilising the onsite available waste heat in another power cycle; this concept is known as topping and bottoming cycle integration. Several ingenious attempts have been made to improve on the performance of the Stirling engine by deploying this approach [13][14][15][16][17][18].…”

“…They utilised the exhaust of the gas turbine to fire the Stirling engine, which led to improving the efficiency of the gas turbine from 23.6% to 38.85%. Entezari et al [16] conducted energetic, exergetic and economic optimisation of a gas turbine and Stirling engine combined power plant. They found a 16.1% increase in the exergy efficiency, 68.5% increase in the net power output and 10.3% decrease in the levelised cost of energy in the combined power plant compared with the standalone gas turbine plant.…”

Techno-economic analysis of a hybrid energy system for CCHP and hydrogen production based on solar energy

“…Due to the high equipment cost, gas external gas turbines and fuel cells have not been widely used. Therefore, the most commonly used generator forms in the distributed energy system are gas turbines, gas internal combustion engines, and micro gas turbines [40].…”

Waste Heat to Power: Technologies, Current Applications, and Future Potential

“…Furthermore, it is simple to power up and is sealed only toward the cold section. [ 25 ] Quite recently the combined operation of GT and SE has been studied from a thermodynamic point of view. Hou et al introduced a double‐action thermoacoustic SE‐based electrical generator capable of recovering liquified natural gas (LNG) cold exergy, converting the external thermal energy into acoustic work (the operating temperature is between LNG and ambient temperature).…”
