| Popis: | Biomasa jedan je od temeljnih izvora obnovljivih izvora energije (OIE), koja ima svijetlu budućnost u daljnjem razvitku novih tehnologija i postrojenja koji koriste obnovljive izvore energije za proizvodnju električne i toplinske energije. Ne zahtjeva uporabu skupih tehnologija, lako ju je proizvesti, te je jedna od ''najčišćih'' oblika izvora energije. No uz sve njezine prednosti, glavni nedostatak je prostor za uzgoj, postizanje značajne ekonomske koristi. Što se tiče isplativosti gradnje samog postrojenja s obzirom na biomasu, tu ima dosta aspekata koji utječu na to. Od investicijskih troškova, troškova održavanja, tarifne stavke, cijene sirovine. Optimalni transport sirovine je do 50 km, ali su kupci prisiljeni platiti i do 90 km, jer je tolika prosječna udaljenost između šume i postrojenja. Svaka biomasa bilo da je ona poljoprivredna ili drvna ima različitu ogrjevnu vrijednost, te što ima veću ogrjevnu vrijednost to je faktor učinkovitosti veći. Za dobivanje energije toplinske ili električne) iz biomase potrebno je postrojenje koje mora obuhvatiti razne tehnološke cjeline od same nabave sirovine, uređaja za obradu biomase, uređaja za dobivanje pare pa sve do uređaja za dobivanje korisne energije koja se dopremljuje potrošaču. Biomass is one of the basic sources of renewable energy sources (RES), which has a bright future in the further development of new technologies and plants that use renewable energy sources for the production of electricity and heat. It does not require the use of expensive technologies, it is easy to produce, and it is one of the "cleanest" forms of energy sources. But with all its advantages, the main disadvantage is the space for cultivation, achieving significant economic benefits. As for the profitability of building the plant itself with regard to biomass, there are many aspects that affect it. From investment costs, maintenance costs, tariff items, raw material prices. The optimal transport of raw materials is up to 50 km, but customers are forced to pay up to 90 km, because that is the average distance between the forest and the plant. Each biomass, whether it is agricultural or wood, has a different calorific value, and the higher the calorific value, the higher the efficiency factor. In order to obtain energy (thermal) or electrical) from biomass, a plant is needed, which must include various technological units, from the procurement of raw materials, devices for processing biomass, devices for generating steam, all the way to devices for obtaining useful energy that is delivered to the consumer.RN EN ISO 13790 standard. |
