Possibilities of use of wood wastes in the power industry of Russia [ВОЗМОЖНОСТИ ИСПОЛЬЗОВАНИЯ ДРЕВЕСНЫХ ОТХОДОВ В ЭНЕРГЕТИКЕ РОССИИ]

... plants with improved environmental characteristics. A comparison was made of the electric energy cost obtained by the use of various types of fuel (gas, diesel fuel, coal, wood chips and wood pellets). An economic comparison of single- and multi-stage gasification of woody biomass has been performed. It is shown that a more promising technology for processing biomass is three-stage gasification due to higher process efficiency. The features of the experimental gas-generating unit under development ...
