Izbira peči za uporabo lesne biomase

Golob, Stanko (author), Bernik, Rajko (mentor)

V diplomskem delu je predstavljeno delovanje peči na biomaso ter izbira najprimernejše peči znamke Herz za domačo kmetijo s kmečkim turizmom, glede na začetno investicijo, ceno in porabo energentov ter dobo povračila investicije. V raziskavi se je pokazalo, da peč na sekance ni primerna zaradi prevelike porabe prostora ter njene velike začetne investicije. Prav tako ni primerna peč na pelete, ker jih je potrebno kupiti, cena le teh je občutno višja kot cena drv in sekancev. Zato smo izbrali peč na drva, Herz Firestar 40 kW, ki je glede na način uporabe in rabo lesne biomase za domačo kmetijo najbolj primerna. Izračun stroškov nam je pokazal, da se začetna investicija, glede na ceno nove in porabo stare peči, povrne v 7 letih. Z novo pečjo Herz Firestar 40 kW, se bo porabilo občutno manj drv, zmanjšali se bodo stroški ogrevanja in ob tem povečal dobiček od prodaje drv na kmetiji.

Abstract

In the thesis operation of a biomass furnace is presented. The choice of the most suitable Herz furnace for a domestic farm with farm tourism according to the initial investment, cost and energy consumption as well as a period of return on investment was adressed. The study showed that the furnace operating on wood chiplets is not suitable due to excessive space consumption and due to a large initial investment. In addition, furnace operating on wood pellets was also found not economic, because all the pellets need to be bought. The price of the wood pellets is substantially higher than the price of logs and wood chips. Therefore, log burning furnace Herz Firestar 40 kW was chosen due to the most efficient and economic application for domestic farm purposes. Calculation of costs revealed that initial investment, taking into account the price and improved efficacy of a new furnace compared to an old one, becomes profitable after 7 years. We conclude that by purchasing of a new furnace Herz Firestar 40 kW significantly less wood is spent, thus reducing the costs of heating and increasing profits from the firewood sale on the farm.
