Plasma technologies for solid fuels: experiment and theory

Comparative study of coal plasma gasification: Simulation and experiment

“…Then these mixtures were investigated experimentally and Vaage law of acting mass, TERRA is based on the principle of 79 maximizing entropy for isolated thermodynamic systems in equi- 80 librium. TERRA has its own database of thermochemical properties 81 for more than 3500 chemical agents over a temperature range of 82 300-6000 K. 83 The process of Kuuchekinski (Kazakhstan) high-ash bituminous 84 coal (Table 1) dynamic equilibration in the system at high temperature of the 97 process [6]. Third, the plasma-chemical reactor is flow-type and 98 quasi-stationary process of gasification is provided.…”

“…57 This paper describes numerical and experimental investigation 58 of coal air and water steam gasification in arc-plasma reactor. First 59 air-coal and steam-coal mixture gasification was investigated 60 numerically with the aid of a thermodynamic program TERRA 61 [6]. Then these mixtures were investigated experimentally and Vaage law of acting mass, TERRA is based on the principle of 79 maximizing entropy for isolated thermodynamic systems in equi- 80 librium.…”

Hydrogen production by coal plasma gasification for fuel cell technology

“…Using this value, the mass-averaged temperature of the reactor contents, T AV , is determined with the help of TERRA code [16]. Reference to the preceding equation shows that, when determining Q SP , only the effective power consumption of the plasma generator is taken into account.…”

“…3. The solid lines are the thermodynamic equilibrium values which were calculated with the software package TERRA [16]. This software was developed for the simulation of high-temperature processes, especially for coal plasma processing.…”

Plasma-aided solid fuel combustion

“…The thermal and chemical equilibrium approach was selected for the calculations of the PFS. For it, TERRA code was used [6]. This method included the formation of the libraries containing the values of species concentrations as a function of the mixture fraction and temperature level.…”
