Plasma activation promotes more effective and environmentally friendly low-rank coal combustion. This paper presents Plasma Fuel Systems that increase the burning efficiency of coal. The systems were tested for fuel oil-free start-up of coal-fired boilers and stabilization of a pulverized-coal flame in power-generating boilers equipped with different types of burners, and burning all types of power-generating coal. Also, numerical modeling results of a plasma thermochemical preparation of pulverized coal for ignition and combustion in the furnace of a utility boiler are discussed in this paper. Two kinetic mathematical models were used in the investigation of the processes of air/fuel mixture plasma activation: ignition and combustion. A 1-D kinetic code PLASMA-COAL calculates the concentrations of species, temperatures, and velocities of the treated coal/air mixture in a burner incorporating a plasma source. The 1-D simulation results are initial data for the 3-D-modeling of power boiler furnaces by the code FLOREAN. A comprehensive image of plasma-activated coal combustion processes in a furnace of a pulverized-coal-fired boiler was obtained. The advantages of the plasma technology are clearly demonstrated.

Abstract. Nanosecond pulsed discharges were applied to an experimental study for exploring the temporal response of a premixed methane/air Bunsen flame with two optical diagnostic methods. The microstructure and dynamic response of flame to the discharges was observed by a schlieren system, and the radial velocity of the shock wave was also measured. Time-resolved optical emission spectroscopy offered intermediate species, their evolutionary timescales and temperature in the plasma region. While the ultrafast heating mechanism of NPD was confirmed, the experimental results also provided lots of critical data for understanding the dynamics of non-equilibrium plasma produced by NPD and performing further numerical simulation. In addition, it also indicates that NPD can stir reactant gases and interact with flame by the generated shock wave and vortices while it produces more reactive plasma than LIBS. It makes the technique may be more suited for applications in combustion enhancement and instability control.

Applications of the modern plasma technology for solid fuel ignition and combustion are presented. This technology provides a more efficient and environmentally friendly low-rank coal incineration. To implement this technology at coalfired thermal power plants, plasma-fuel systems (PFSs) were developed. The PFS is a pulverized coal burner equipped with an arc plasma generator producing a high temperature air stream of 4000°C-6000°C. The PFS technology is plasma thermo-chemical preparation of coal for burning. It includes plasma heating of air-coal mixture up to the temperatures, when coal volatiles are released and partial gasification of char carbon occurs. To show the advantages of plasma-aided coal combustion as compared with the conventional one, the numerical simulation of the process was carried out. The numerical modeling was performed for the low-rank bituminous coal of 40% ash content incinerated at a boiler of 420-t/h steam productivity. Full-scale trials of the plasma-aided combustion confirmed the possibility of high-ash coal ignition in the cold furnace without heating of primary air.
