Direct Current (DC) plasma torch is a device which makes it possible to generate and maintain partially ionized gases (plasmas) at high temperature (>10,000). Its industrial and scientific use is extremely diverse and ranges from thermal spray coatings to process metallurgy and to waste destruction.The objective of this project is to develop a high-power, efficient, hazardous waste incineration tool which is based on a novel direct current (DC) plasma torch operated with carbon containing gas mixtures. A prototype of the torch which operates at a power level of up to 70 kW has already been built, tested, and an application for a provisional US patent has been filed. Specifically, we propose to: Upgrade and build a newly developed DC plasma torch so that it can be operated at a power range of 150-300 kW. Plasma gases are a mixture of hydrocarbons and carbon dioxide. The cathode is made of highly ordered graphite.

直流（DC）等离子体炬是一种能够在高温（> 10，000）下产生和维持部分电离气体（等离子体）的设备。它的工业和科学用途非常广泛，从热喷涂涂层到加工冶金和废物销毁，该项目的目标是开发一种高功率，高效的危险废物焚烧工具，该工具基于一种新型的直流（DC）等离子体炬，用含碳气体混合物操作。一个功率高达70千瓦的火炬原型已经建造、测试，并已申请美国临时专利。具体来说，我们建议：升级和建立一个新开发的直流等离子炬，使其可以在150-300千瓦的功率范围内运行。等离子体气体是碳氢化合物和二氧化碳的混合物。阴极由高度有序的石墨制成。
