将过渡的“热”等离子体放大到工业水平，使开发结合了热放电和非热放电优势的等离子体系统成为可能，例如，在高压和平均功率密度下，低温和高工艺选择性(与热等离子体相比)。在2-3千瓦的功率水平上证明了非平衡“冷”滑行弧光(观察到平衡到非平衡的转变)，并被证明是几个等离子体化学和等离子体催化过程的高效等离子体刺激器，包括生物质、煤和有机废物产生氢/合成气、废气净化、燃料脱硫和新出现的污染物的水净化。滑动电弧的演化包括初始微弧相的快速转变到电场升高、低气体温度和高电子温度的非平衡瞬变相，以及选择性地产生冷等离子体特有的活性物质。本文将描述实验上实现的将非平衡滑动弧放电放大到10-15千瓦的水平，以及这种强大的非平衡等离子体系统的理论放大限制。
Scaling up of transitional “warm” plasmas to industrial level gives possibility to develop plasma systems that combine advantages of thermal and non thermal discharges such as low temperature and high process selectivity (compare to thermal plasma) at high pressure and average power density. Non-equilibrium “cold” gliding arcs (with observation of equilibrium to non equilibrium transition) has been demonstrated at power level 2–3 kW and proved to be a highly efficient plasma stimulators of several plasma chemical and plasma catalytic processes, including hydrogen/syngas generation from biomass, coal and organic wastes, exhaust gas cleaning, fuel desulfurization and water cleaning from emerging contaminants. The gliding arc evolution includes initial micro-arc phase with fast transition to transient non-equilibrium phase with elevated electric field, low gas and high electron temperatures, as well as selective generation of active species typical for cold plasmas. The paper will describe experimentally achieved scaling up of the non-equilibrium gliding arc discharges to the level of 10–15 kW, as well as theoretical scaling up limitations of this powerful non-equilibrium plasma systems.
