The project is being implemented from 2017 to 2020 by Priority 1 of the EU Investment Funds Promotion of Research, Experimental Development and Innovation and program NR J05-LVPA-K Intellect. Common scientific and business projects. The project is co-ordinated by JSC “Enerstena” with the participation of KUT and LEI energy science departments. The aim of the project is to create an effective technology that utilize renewable energy sources based on combustion of biofuels and heat recovery from flue gases. KUT participates in the process of developing the system Combined Combustion Air Moisturizer, Capture Device for Solid Particles, Condensing Economizer System with Optimized Parameters and Hydrodynamic Droplet Separator.
Project funding:
This research project is funded by European Regional Development Fund according to the 2014–2020 Operational Programme for the European Union Funds’ Investments under measure No. J05-LVPA-K “Intellect. Joint Science-Business Projects”
Project results:
The results of the numerical investigation have been used to perform the experimental investigations. For this purpose a special experimental setup section was constructed to investigate the water droplets warming and phase transformations in the humid flue gases. A lot of experimental investigations have been performed, which helped to solve these uncertainties:
1. The uncertainties of experimental investigations in hot and humidified air;
2. The results of experimental investigations of water droplets heat transfer and phase transformations in humidified flue gases:
a. the uncertainty of droplet thermal state variation in the transit phase change cycle;
b. uncertainty of droplet diameter variation in transit phase change cycle;
c. the uncertainty of water droplet thermal state in phase transformation change cycle.
In biofuel flue gases the peculiarities of sprayed water droplets heat transfer and phase transformation are defined by factors of flue gases temperature and humidity, water temperature and droplet heating process. In droplet warming process the important role is provided for droplets dispersity and droplets slipping velocity in flue gases. In high temperature flue gases a radiation flux absorption in a semi-transparent water droplets has a certain role.
In this project the results of the experimental investigations and numerical modelling of the thermal state variation and phase transformations of water droplets in the humid flue gas flow have been summarised by scientific conclusions and practical recommendations have been provided for the company’s equipment modernisation.
