采用 100 kW 的非转移直流蒸汽 (H2O) 等离子体来最大限度地减少有毒副产物的产生，例如二恶英和呋喃，这些副产物的形成在传统焚烧中是不可避免的。在多氯联苯(PCB)混合物废物的蒸汽等离子体工艺中，可用作气态燃料的可燃气体含量以湿气计约为30%。对于27% PCB 和73% CCl4 的混合物，PCDD/PCDF 的总毒性当量浓度约为0.056 ng TEQ/N m(3)。结论是，蒸汽等离子炬工艺对于垃圾发电和危险废物处理比注入蒸汽的空气等离子炬工艺和传统焚烧工艺更有效。 (C) 2003 Elsevier Science Ltd. 保留所有权利。
Non-transferred DC steam (H2O) plasma working with 100 kW was applied to minimize production of the toxic byproducts such as dioxins and furans of which formation is not avoidable in the conventional incineration. In the steam plasma process of polychlorinated biphenyl (PCB) mixture waste, content of combustible gas that can be used as gaseous fuel was about 30% based on wet gas. For the mixture of 27% PCB and 73% CCl4, total toxic equivalent concentration of PCDD/PCDF was about 0.056 ng TEQ/N m(3). It is concluded that the steam plasma torch process was more effective for waste-to-energy and hazardous waste treatment than the air plasma torch process injected steam and the conventional incineration process.
