Design of heat exchanger for Ericsson-Brayton piston engine

Area of Science:

• Energy Engineering
• Thermodynamics
• Renewable Energy Systems

Background:

• Combined heat and power (CHP) generation offers higher efficiency than separate production.
• Current CHP systems heavily rely on fossil fuels like natural gas and coal.
• There is a growing need for sustainable energy sources to mitigate fossil fuel dependency.

Purpose of the Study:

• To investigate the principles of hot-air engines.
• To evaluate their application in combined heat and electricity production using biomass.
• To analyze the role of heat exchangers in this process.

Main Methods:

• Review of hot-air engine principles (Stirling, Ericsson engines).
• Analysis of biomass as a fuel source for external combustion engines.
• Examination of heat exchanger performance in energy transfer.

Main Results:

• Hot-air engines offer an alternative for external combustion, suitable for biomass.
• Heat exchangers are crucial for efficient energy transfer from combustion gases.
• Integration of these engines can enhance overall energy system efficiency.

Conclusions:

• Hot-air engines are a viable technology for biomass-based combined heat and electricity generation.
• Optimizing heat exchangers is key to maximizing efficiency.
• This approach contributes to diversifying energy sources and reducing reliance on fossil fuels.
