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 ...

The utilization of combustible waste, such as sewage sludge, can be combined with energy production for small:scale consumers. One of the ways of such utilization can be gasification, which ma: kes it possible to obtain combustible gas suitable for thermal and electric energy production. The aims of the study are: to evaluate the efficiency of sewage sludge co:conversion with higher quality fuel (brown coal) based on ...
