Optimisation and operation of small district heating networks using renewable energy sources was the topic of the fourth local training organised within the ENTRAIN: Enhancing renewable heat planning for improving the air quality of communities project, funded by the Interreg Central Europe programme. The event took place on 15 February 2022 and was the last of a series of four training courses, each dedicated to different aspect of district heating.
The training started with a short welcome and introduction of participants to the subject matter of the meeting as well as the scope of the ENTRAIN project, under which we met, was presented.
The first speaker was Prof. Andrzej Osiadacz, D.Sc. from the Faculty of Building Services, Hydro and Environmental Engineering at the Warsaw University of Technology. The presentation covered the topic of simulation and optimisation programmes and their application in the management of district heating networks. The professor drew attention to the main objective of network management, i.e. minimisation of its operating costs. He also presented the basic factors which should be taken into account during network optimisation and the sources of data for calculation packages.
The second speaker was Mr. Łukasz Kamiński, Director of Energy Efficiency from Egain Polska, who spoke about the possibilities of using a building heat management to improve the efficiency of installations and reduce energy consumption. The participants learned, among other things, what variables are taken into account when creating algorithms for controlling heat quantity in buildings, what are the basic elements of such systems and how they work. Then, on the example of Polkowice Municipal Office building, the benefits of using a management system were presented. The use of such system brings energy savings of about 15% for residential buildings and 20% for public buildings.
The next presentation, covering the practical application of heat and cold storage systems, was delivered by Mr. Tomasz Mania, CEO of the Association of Polish Heat Pump and a representative of the University of Bydgoszcz. He presented various heat and cold storage technologies and examples of their application in Poland and abroad.
After a short break, the floor was taken by Mr. Andrzej Piotrowski form Veolia Energy Poland. The presentation covered the extension of the heat plant in Zamość with a small RDF heat plant, during which the investment schedule was presented and the importance of public education in the implementation of such investments was emphasised. Additionally, the speaker characterised the situation in Poland and Europe, regarding energy recovery plants, and indicated that they are fully safe for the local residents.
The last speaker was the CEO of MPEC Sp. z o.o. in Łomża, Mr. Radosław Żegalski. His speech concerned the installation of biomass combustion in MPEC in Łomża. He presented the parameters of this installation, energy data and the environmental and economic benefits resulting from its use, and also spoke about the next investments planned by the company.
We would like to thank all the speakers for sharing their knowledge and experience during this event. We hope that you found it valuable and that the information gained will contribute to well thought-out and responsible actions connected to the development of small heating systems using renewable energy sources.
We also encourage you to read the materials form the first, second and third training courses organised within the ENTRAIN project.
