The Heating Association of the Czech Republic awarded five Projects of the Year 2019 with crystal chimneys at the Days of Heating and Energy: replacement of steam pipelines in Brno - Zábrdovice, greening of boilers in Ostrava Ostrava Power Plant and Olomouc Heating Plant, modernization of source using biomass, cogeneration and heat accumulator in Ostrov nad Ohrí, a new heat pipeline to Planá nad Lužnicí and a project of on-line monitoring of energy consumption in Pilsen schools
Since 2002, 65 district heating projects have received this prestigious award. The traditional announcement of the results of the Projects of the Year took place during the gala evening of the Days of Heating and Power Engineering in Hradec Králové. A total of 17 of last years most interesting projects were selected for shortlisting in 5 categories. In the history of the competition so far, Veolia Energie CR (10) received the most Project of the Year award, followed by companies from the MVV Energie CZ Group (7), the CEZ Group and Plzenská teplárenská (6 awards each).
Prizes to the winning projects of the five competition categories, to the Chairman of the Executive Board of District Heating Association of the Czech Republic Tomas Drápela, who said: " If we look at the winning and nominated projects, we can proudly say that heating is well seized the opportunity to develop a modern, environmentally friendly and heat supply services. It is necessary to appreciate those who can complete new projects and move the field forward. I repeat, but I am very glad that there are not a few of them at all and we still have something to choose from. "
The title Project of the Year in heat and cooling supply systems for 2019 was awarded to:
Teplárny Brno, as, for the project Replacement of steam pipelines in the locality Brno - Zábrdovice (category Reduction of heat losses, transition to more efficient hot water distribution).
In 2019, Teplárny Brno laid another 8.2 km of new hot water pipelines, especially in the Zábrdovice district, and 53 supply points were connected. The transition from steam to hot water is one of the largest projects of Brno Heating Plants in their history and was started in 2010. Of the original 97 km of steam networks, only 66 km of hot water will be restored thanks to optimization with the same coverage of the supplied area.
To complete the entire project, only 15 km of steam pipelines need to be replaced. Every kilometer of steam pipeline replaced by a hot water pipeline means an annual reduction in emissions of 336 tons of CO2. The completed conversion of steam pipelines will have the same effect as if ten thousand cars disappeared from the city of Brno.
Veolia Energie CR, as, for the project Greening of boilers K13 in the Ostrava Trebovice Power Plant and K5 in the Olomouc Heating Plant (category Reduction of air pollutant emissions).
The greening of the K13 steam boiler was completed at the Trebovice Power Plant in Ostrava. Denitrification, desulphurization unit and other modifications cost more than half a billion crowns. The amount of nitrogen oxides (NOx) and sulfur dioxide (SO2) released into the air from the K13 boiler will decrease by more than 70% and the amount of dust (TZL) by a third. Also in the Olomouc Heating Plant, the greening of the K5 fluidized bed boiler, which burns mainly brown coal, was successfully completed.
There has been a significant reduction in NOx and SO2 emissions, and in dedusting the source even reaches half the limits for the best available technologies. In absolute numbers, for example, in the case of dust, measures in Olomouc between 1995 and 2020 will reduce emissions by 98% per year.
Ostrovská teplárenská, as, for the project Modernization of the source using biomass, cogeneration and heat accumulator (category: Development and use of CHP, renewable and secondary energy sources).
In Ostrov, it was necessary to proceed with the complete modernization of the heating plant. The three original steam coal-fired boilers were gradually replaced by new hot-water boilers. This was made possible by the transition from steam distribution to hot water completed in 2016. In September 2016, a hot water boiler for biomass was completed, in August 2017 a hot water gas boiler and in December 2018 a hot water coal boiler was put into operation.
In April 2019, a gas cogeneration unit was launched, and last October, the entire source was supplemented by a heat accumulator. Thanks to new energy sources, emissions of sulfur, nitrogen and CO2 oxides from fossil fuels were reduced by half or more and by one third by more than in 2015.
C-Energy Planá sro, for the project Teplovod do Plané and replacement of local heat sources (category Development of heat supply systems).
The construction of a 3.6 km long heat feeder from the C-Energy heating plant to Planá nad Lužnicí made it possible to connect selected buildings to the heat supply system. The hot water feeder ends with an exchanger station at the Unistroje complex, which serves several small companies with joint energy management. Furthermore, the heat pipe is divided into two basic branches.
One supplies the center of Planá with a primary and kindergarten, a nursing home, a restaurant and multi-storey apartment buildings. The second branch is connected to the Window Star industrial plant and another nursing home. The supplied heat is produced in the process of highly efficient combined heat and power generation.
Plzenská teplárenská, as, for the Project of on-line monitoring of energy consumption in schools (category Improving services and customer care).
On the project, Plzenská teplárenská cooperates with the Plzen 3 Municipal District in selected kindergarten buildings. Based on online monitoring, it is possible to find out the course of energy consumption and optimize the operation of the building even outside working hours in order to save energy.
Energy meters in buildings are equipped with sensors and the transmitted data is stored in the control room. In case of finding above-limit energy consumption, the actual situation is checked in cooperation. Continuous monitoring concerns not only the consumption of heat energy, electricity, gas and water, but can also be extended to the quality of the indoor environment in the building (temperature, humidity or CO2 concentration).
The intention of evaluating the best projects is to appreciate successful implementations in the field of district heating and cooling, which contribute to the development and modernization of efficient, economical and environmentally friendly heat supply systems and effectively ensure the thermal comfort of apartments and energy needs of services and industry. Between 2001 and 2019, a total of 190 district heating projects had already been nominated for this nationwide energy competition. |
