Abstract:Cene energentov po svetu strmo rastejo. Tudi v Šaleški dolini in v Komunalnem podjetju Velenje smo se začeli soočati z težavo višanja cen energije. Prav tako so okoljevarstvene zahteve vedno višje. Aktualna problematika v Šaleški dolini je zaprtje Premogovnika Velenje. S tem so se odprla vprašanja glede zagotavljanja količine potrebne toplotne energije in redne dobave le-te. Prav tako je neznanka cena toplotne energije iz Termoelektrarne Šoštanj. Naslednja zahteva je nov zakon o spodbujanju rabe obnovljivih virov energije (ZSROVE) za učinkovito daljinsko ogrevanje. V tem zaključnem delu smo predstavili trenutno stanje daljinskega ogrevanja v Šaleški dolini. Nadaljevali smo z predstavitvijo razpoložljivih energetskih virov v Šaleški dolini. Sem spadajo OVE s kotlovnico na lesno biomaso in SPTE na lesno biomaso, OVE sončne energije, termična obdelava komunalnih odpadkov, odpadna toplota iz industrijskih in komunalnih sistemov, geotermalna energija in energija jezer v Šaleški dolini. Prav tako smo določili možne mikro lokacije za postavitev teh obnovljivih proizvodnih virov toplote. Potem smo pogledali možnost vgradnje hranilnikov toplotne energije v sistem daljinskega ogrevanja. Pojavljajo se potrebe po hitri regulaciji elektroenergetskih omrežij, ki jih ustvarja povečana proizvodnja električne energije iz OVE. Podrobno smo si ogledali možnost koriščenja nizkocenovne električne energije s hitro odzivnimi in visoko napetostnimi elektrodnimi kotli. Preračunali smo potrebne moči in jih integrirali v sistem daljinskega ogrevanja v Šaleški dolini.

Title:Use of renewable energy sources for heat energy production in the Šaleška valley
Abstract:Energy prices around the world are rising. Even in Šaleška dolina, and thus in the communal company Velenje, we started to face the problem of rising energy prices. Also, the environmental protection requirements are higher and higer. The current issue in the Šaleška Valley is the closing of the Velenje Coal Mine. This opened up questions regarding the guaranteed amount of required thermal energy and the regular supply of only this. The price of thermal energy from the Šoštanj Power Plant is also unknown. The next requirement here is a new law on promoting the use of renewable energy sources (ZSROVE) for efficient district heating. In this final part, we presented the current state of district heating in the Šaleška Valley. We continued with the presentation of the available energy sources in the Šaleška Valley. These include RES with a wood biomass boiler and wood biomass CHP, solar RE, thermal treatment of municipal waste, waste heat from industrial and communal systems, geothermal energy, energy from the lakes in the Šaleška Valley. We have also determine possible micro-locations for the installation of these renewable heat production sources. Then we looked at the possibility of installing thermal energy storage in the district heating system. Due to the need for rapid regulation of power networks, which is created by the increased production of electricity from RE. We looked in detailed at the possibility of using low-cost electricity with fast-response and high-voltage electrode boilers. We calculated the required power and integrate it into the district heating system in the Šaleška Valley.
Keywords:renewable energy sources, cogeneration, biomass, high voltage cathode boilers, heat energy
