中文摘要: 为了研究层流等离子体发生器结构对发生器热效率的影响,进而指导层流等离子体发生器的设计,通过实验获取了两种不同结构层流等离子体发生器在相同工作参数下的弧压和热效率。根据实验结果对两种不同结构层流等离子体发生器的弧压特性和热效率进行对比分析。分析结果表明:采用纯氮气作为工作气体时,在相同工作参数下,虽然分段式阳极结构层流等离子体发生器的弧压较高,但其热效率较传统两极式层流等离子体发生器低。
Abstract: In order to study the influence of the torch constriction on the thermal efficiency, and then to guide the design of laminar plasma torch, the arc voltage and thermal efficiency of two laminar plasma torches with different constriction, working with the same working parameters, were obtained by experiments. Based on the experimental results, the arc voltage and thermal efficiency of the two plasma torch were compared and analyzed. The results show that: working with pure Nitrogen, although the arc voltage of the segmented anode laminar plasma torch (MEPT) is much higher than that of the conventional laminar plasma torch (TEPT), the thermal efficiency of MEPT is much lower than that of TEPT.
