The article proposes a technological scheme of the process obtaining alternative fuels from local biomass by method heliopyrolysis. A schematic diagram solar concentrator experimental pyrolysis device has been developed, and samples (pyrogas, liquid, solid fuels) have obtained as result thermal processing biomass. also examines heat material balance heliopyrolysis device. use made it possible t...

this paper tries to systematically survey, with taking theoretical view on geomorphic basin and its changes into account. the purpose of this research is to determine the balance and stability of geomorphic basins from the past to present and then to future. consequently, it tries to determine the balance between energy and input-output materials for example (rainfall , solar radiation, tectoni...

The material balance used previously in one-dimensional mathematical models of porous electrodes is invalid when there is a nonzero volume change associated with the reaction. It is shown here how the material balance should be modified either to account for a loss in volume, or to account for an inflow of electrolyte from the header into the active pores. A one-dimensional mathematical model i...
