          Wobbe-Index and Air demand  沃泊指數分析儀 RHADOXTM 用于快速分析沃泊指數和助燃空氣需求量。分析儀測量的基本原理是在樣品實現完全燃燒后分析燃燒過程空氣需求量。對樣氣燃料氣體和空氣在理想的溫度和壓力下進行混合均勻所混合物,然后在催化反應器中氧化。在氧化過程中氧含量的氣體混合物被連續測量。通過內置的校準計量參數測量得到沃泊指數和需氧量。沃泊指數和需氧量是控制穩定燃燒控制的重要的基本參數。

          The RHADOX™ Analysers are mounted on a metal mounting plate with the components catalytic
          reactor, gas mixing chamber, electronic evaluation unit, power supply and measuring signal
          distribution installed in separated sheet metal housings. The housings of the components are
          manufactured for General Purpose in protection class IP 65. If required the RHADOX™ Analysers can also be supplied as integrated system installed in a analyser shelter including gas monitoring. The analyser shelter does not have to be air conditioned. However the operating temperature has to be observed (see technical data below). The Wobbe-Analyser RHADOX 1000 is calibrated by using two calibration gases which represent the low and high measuring range which have to be determined for every Off-gas individually. The calibration is started manually from the analyser main menu. Integrated automation components allow access to the system by remote control. The RHADOX™ Analysers are available for use in hazardous areas classified as Zone 1 and 2. The RHADOX™ Analysers are designed for continuous operation in industrial applications.
