Economic indicators of pelleted biomass combustion

Exploitation of renewable resources in Vojvodina is important not only from the aspect of current energy shortage and high prices situation, but also from the aspect of constant depletion of fossil fuels and the growing problem of environment pollution. The additional importance, especially in the case of Serbia, stems from the fact that the approach to the energy problem is essential for its EU accession. Due to the ever more intensive urbanization, there is a growing demand for fossil fuels, which only aggravates the actual energy problem. In this paper, the costs of thermal energy - produced by burning straw and other renewable resources, and required for residential and office heating in urban areas - are compared to the costs of energy from other energy resources. The calculations took into account all important differences which are specific to combustion technology of the analyzed energy resources. Also presented in this paper is economic feasibility study of pelleting and pellet combustion. Minimum pellet price used by the remote heating boiler plant in Petrovaradin, amounts to 9.988 d/ton, VAT not included. The market price is somewhat higher and equals 12.400 d/ton for pellets, VAT not included. Based on the economic feasibility of investment into a 3,5 MW hot water boiler plant, run with biomass pellets, the authors concluded that the costs of the produced thermal energy equal 5,04 din/kWh. In the case when the pelleted biomass is purchased by the market price, the costs of produced thermal energy would be 5,68 din/kWh.
