Experimental and Mathematical Investigation of the Thermophysical Properties of Coal–Water Slurries Based on Lignite

The burning of organic fuel is one the main factors influencing greenhouse effect on climate planet. article examines influence properties lignite and coal–water slurries amount carbon dioxide molecules formed as a result chemical reactions. authors give an overview results other researchers in recent years their research development field industrial recycling plants. present experimental studies thermophysical coal mixture. obtained were compared with calculations using mathematical model numerical modeling Ansys. New methods approximation step functions used for model. These make it possible to reduce errors thermal coal. proposed do not have disadvantages traditional decompositions into Fourier series can be problems wide class processes systems. In particular, when determining coefficient kinematic viscosity, ash content, humidity by method data, use new makes error calculations. addition, data hydraulic transport combustion are provided, validation procedure carried out. convergence shown location selected band uncertainties satisfy requirements verification adopted European Union Eurasian Union.
