Abstract:Pri pridelavi okrasnih rastlin in zelenjave potrebujemo v našem podnebnem pasu dodatno ogrevanje v hladnejših delih leta. V zadnjem času se zaradi ekološkega vidika in višanja cen fosilnih goriv, pojavlja potreba po alternativnih načinih ogrevanja. Namen diplomske naloge je bil preučiti, ali je ogrevanje na lesne sekance primerna alternativa oljnim pečem. Ker gre za dokaj nov način ogrevanja na vrtnarijah, je bilo pomembno raziskati tehnične pomanjkljivosti in rešitve, ki se lahko pojavijo pri adaptaciji ogrevalnega sistema. V kurilnem obdobju 2010/2011, ki je trajalo od 28. oktobra do 15. aprila je bilo skurjenih 450 m3 lesnih sekancev različnih drevesnih vrst. Izračunan ekvivalent porabljene količine kurilnega olja v istem obdobju pa bi znašal 35 549, 42 litrov. Zaradi cenejšega načina ogrevanja, bi znašala doba amortizacije 7 let. Ob upoštevanju dobljenih izračunov lahko z gotovostjo trdimo, da je ogrevanje vrtnarij na lesne sekance primerna alternativa oljnim pečem, kljub dejstvu da je začetna investicija še vedno visoka.

Title:RECONSTRUCTION OF HEATING SYSTEM FOR REQUIREMENT OF GREENHOUSE
Abstract:For the production of ornamental plants and vegetables we need in our climate zone further heating in the colder parts of the year. Recently, due to ecological and rising prices of fossil fuels, there is a need for alternative means of heating. The purpose of the thesis was to examine whether a wood chip heating is a suitable alternative to oil-fired boilers. Since this is a fairly new method of heating greenhouses, it was important to explore the technical deficiencies and solutions that may affect the heating system renovation. In the 2010/2011 heating season, which lasted from 28 October to 15 April there were burned 450 m3 chips of various tree species. Calculated equivalent amount of oil consumed in the same period would amount to 35 549, 42 liters. By low-cost heating, the annual savings would reduce the amortization period to 7 years. Taking into account the resulting calculations, we can confidently say that heating greenhouses with woodchips is a suitable alternative to oil-fired boilers, despite the fact that the initial investment is still high.
Keywords:wood biomass, oil-fired furnaces, greenhouses, heat loss, fuel consumption
