摘要

摘要: 在300 kW管式电弧加热器上，通过试验测定了CO₂介质和空气介质条件下的伏安特性和热效率数据。基于相似参数进行回归分析，得到了可同时应用于CO₂介质和空气介质的电热特性关系式，并与国外类似电弧加热器进行了比较。研究结果表明：CO₂和空气电弧加热器的电热特性相似，在相同输入参数（电弧电流、气体质量流量）下，CO₂介质比空气介质条件下的弧室总压平均低18%，但电弧电压、焓值和热效率分别高5.9%、6.7%和10.9%；通过统一关系式得到的数据和试验数据一致性较好，伏安特性和热效率回归误差分别为−13%～11.4%和−33.0%～34.7%。

Abstract: On the 300 kW DC axial tube electrode arc heater, the U–I characteristics and thermal efficiency of CO₂ and air are measured by experiment, and the regression analysis is carried out by using the similarity criterion number. The unified relationship of electric and thermal characteristics that can be applied to the two media is obtained, and compared with similar heaters abroad. The results show that CO₂ and air arc heaters have similar electric and thermal characteristics, under the same input parameters (arc current and gas flow); the total pressure of CO₂ is 18% lower than that of air, but the arc voltage, enthalpy and thermal efficiency are 5.9%, 6.7% and 10.9% higher respectively; the regression errors of U–I characteristics and thermal efficiency are −13.0%～11.4% and −33.0%～34.7% respectively. This relationship plays an important guiding role in the operation and commissioning of the high-power arc heater.
