“…One possible solution is 'pulverised fuel thermo chemical preparation' of the coal using plasmas [1][2][3][4][5][6][7][8]. In this concept a fraction of the pulverised coal and air mixture, diverted away from the bulk of the flow, is heated by electric arc plasma within a separate plasma chamber.…”

The main goal of this research is to show the action of pulverized coal in the plasma chamber through computer simulation and numerical experiments carried out with the aid of developed well known thermodynamic, kinetic and multi dimensional computational fluid dynamics based on mathematical models. The data needed for the validation of the numerical procedure were obtained from a cylindrical direct flow burner equipped with a plasmatron (plasma generator) with 100kW of electric power and mounted on a full-scale boiler (Gusinoozersk TPP, Eastern Siberia). The experiments were carried out using 'Tugnuisk' bituminous coal. Two mathematical models were employed: the one ('1D Plasma-Coal') being one-dimensional, but with an emphasis on complex chemistry, the other (3D FAFNIR) being fully three-dimensional with emphasis on the geometry and overall combustion processes. 1D Plasma-Coal numerical experiments gave the predicted temperatures and velocities of gas and solids along the chamber length; while the concentrations of the gas components (CO, CO2, H 2 , CH 4 , C 6 H 6 , N 2 , H 2 O) were reported for the chamber exit. The degree of coal gasification showed that 54% of coal carbon was gasified within the plasma chamber. 3D numerical results for plasma jet spreading length were in good agreement with the measured data, while the temperature profiles within the plasma chamber were over predicted. The predictions of main species concentrations reveal that oxygen was completely consumed with the exit product stream consisting of combustible gases, un-burnt volatiles and char particles.

“…In this paper we consider the fabrication of nano structured carbon products of hydrocarbon gas pyrol ysis in dc arc plasma torches used for plasma ignition of coal [2][3][4][5]. The lifetime of plasma torch electrodes can be extended by regeneration of the electrode material, which consists in the deposition of atoms and ions from near electrode plasma on their active surface.…”

The results of an instrumental study of a deposit formed on the electrodes of an arc plasma torch with propane-butane mixture feeding into the interelectrode gap are presented. The optical, electron, and Raman microscopy techniques have been used in the study. According to Raman spectra, the cathode deposit contains various forms of nanocarbon. It has been found that maleic anhydride is synthesized and covalently grafted to nanographite in the absence of a specialty catalyst during plasma torch operation. Having a large specific surface area, the nanocarbon itself acts as a heterogeneous catalyst in this case. It has been shown that an arc plasma torch of this design with a hydrocarbon feed gas can be considered a mini reactor for synthesis of different forms of nanocarbon, its surface modification, and alteration of physicochemical properties.
