Otpaci od drvne biomase kao novi materijali za gasifikaciju u CHP postrojenjima

Abstract

Kako u Srbiji ne postoje zvanične procene raspoloživosti biomase prema međunarodno priznatoj metodologiji, ovaj rad predstavlja pokušaj da se na bazi prikupljenih podataka iz šumske seče i prerade drveta te procene izvrše. U radu se ukazuje na oblasti u Srbiji sa najvećom sečom i drvnim otpatkom, kao i na vrste drvne industrije koje ga proizvode. U industriji prerade drveta razmatrana je potrošnja energije u primarnim tehnologijama. Izračunata je količina drvnog otpatka neophodna da dobijanje električne energije za potrebe primarne prerade. Izvršena je procena količine otpatka i cene 1kWh za rad demonstracionog CHP postrojenja snage 200 kWe, za kombinovanu proizvodnju toplotne i električne energije, koje je u izgradnji u okviru projekta TR-33049, koje finansira Ministarstvo prosvete i nauke Republike Srbije. Objašnjena su dva principa rada CHP postrojenja, sa i bez Stirlingove mašine, kao moguća rešenja za pomenuto demo postrojenje. .

As in Serbia, non-existent official estimates of biomass availability to the internationally recognized methodology, this paper attempts to collect based data from forest harvesting and wood processing, and perform assessment. The paper points out the regions in Serbia, the largest producers of scrap wood forest after logging, as well as the type of timber industries that produce it. In the industrial processing of wood energy consumption is considered in primary wood processing technologies. The consumption of wood waste necessary for obtaining electrical energy is calculated. Estimation of the amount of scrap and the price of kWh of electrical energy is done for the demonstration CHP plant power 200 kWe, for heat and electricity, which is under construction on Project No. TR-33049 financed by the Ministry of Education and Science Republic of Serbia. At the end, the two principals of working CHP plant are given, with and without Stirling machine, as a possible solution for the mentioned demo plant. .
