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 ...

Series. Vol.891. No.1. ID: 012200. 2017. DOI: 10.1088/1742-6596/891/1/012200 The paper is concerned with an integrated system of internal combustion engine and mini combined heat and power plant (ICE-CHP). The system is based on multi-stage wood biomass gasification. The use of producer gas in the system affects negatively the internal combustion engine performance and, therefore, reduces the efficiency of the ICE-CHP plant. A mathematical model of an internal combustion engine running on low-calorie ...
