 Start / End Dates:  31 July 2020 / 27 January 2023

 

The research project TRI-MAX has as main objective the development, construction and experimental assessment in real environment of a thermal engine based on Trilateral Flash Cycle (TFC), with the cycle power output estimated around 10-15 kW and a cycle design which will take place for low temperatures (up to 130oC), while the project goal is the efficiency increase of the thermal energy conversion to electricity. The commercial application concerns the low temperature heat recovery market in the industrial sector which is estimated at 300 TWh/year in the EU with one third being low temperature, and the biogas market due to attractive subsidy policies. As it is already mentioned the initial goal of this project is to demonstrate in real life that the efficiency increase of the thermal energy conversion to electricity, up to 20% in comparison with the traditional ORC technologies. One of the critical parameters for the accomplishment of this scope relies on the semitropical efficiency of the expander which have to be around 60-70%. The methodology that is going to be followed in this specific project divided into four basic levels. The first three are mainly dedicated in the study and analysis of the two-phase flow during expansion with the aim of understanding the whole process in terms of mass and heat transfer. Moreover, they are focused in the development of the simulation and optimization tool for the expansion process and the entire cycle, in order to maximize the cycle efficiency according to the 1st and 2nd Thermodynamic Laws.

The specific objectives to be achieved for the project successful completion, are:

Objective 1 - Study and analysis of the two-phase flow during expansion, in order to evaluate how it affects the whole cycle.

Objective 2 - Analysis of the power cycle processes in order to optimize its efficiency.

Objective 3 - Development of the simulation and optimization tool for the expansion process and the entire cycle.

Objective 4 - Detailed design of the TFC for 10-15 kW and test runs.

Objective 5  - Experimental tests for the cycle operation in laboratory.

Objective 6  -  TFC tests in real field.

Objective7 – Technoeconomical assessment of TFC and comparative analysis with competitive technologies.

 

Lead partner: CENTRE FOR RESEARCH & TECHNOLOGY HELLAS/ DIVIDION OF CHEMICAL PROCESS AND ENERGY RESOURCES (CERTH/CPERI)

Partners:

CERTH (Technical  Coordinator) as a research partner with highly recognized experience in the study-analysis of thermal processes has undertaken in the framework of the project the investigation of the two-phase expansion and the development of computational tools with the aim of understanding the whole process in terms of mass and heat transfer. In the analysis, only modern organic fluids and mixtures of the 4th generation (safe, with zero ODP and negligible GWP) will be considered in order to fully align the project with the applicable policies for environmental safety and protection.
