Mathematical modeling of mini-CHP based on biomass

... studies of an mini-CHP based on multi-stage biomass gasification. Mathematical models of elements and mini-CHP in general based on technological schemes were constructed. The mathematical models were constructed with the software developed at Melentiev Energy Systems Institute of Siberian Branch of the Russian Academy of Sciences. The calculations were made for two sizes of internal combustion engines. Thus, we obtained the values of flow rates, temperatures of heat carriers at various points of flow ...

Analysis of the scale of the implementation of the energy security threats in Russia up to 2030 and the main directions for the neutralization of these threats

... factors affecting the strengthening or weakening of these threats are shown. The estimation of the country's total needs in primary energy resources and the required volumes of gas to fully cover these needs (taking into account the capabilities of other energy systems of the fuel and energy complex) is made. The total possible levels of Russian gas exports for the future are estimated. The possibilities of fuel and energy complex industries for the perspective satisfaction of the needs of domestic and ...
