I 0000069208 00000 n The Wobbe Index indicates the interchange ability of a fuel gas and is the best indicator of similarity between natural gas and a specific propane-air mixture. การคำนวณหาค่า Wobbe Index และปรับเปลี่ยนส่วนผสมของก๊าซ. Glass and porcelain factories (furnaces & ovens control), Mixing and/or blending of gas streams with variable compounds, Sample Probe, fully customized in accordance with Process & Design requirements, Sample line, engineered to guarantee the best, Conditioning System, engineered and made in accordance to any different process plant with different gases and different level of dirtiness, Analysis Section based on stand-alone analyser or integrated system, suitable for  Safe Area or Haz Area, Validation Section based on pressurized bottles and pressure reduction system, also with remote control, I/O , HMI interface, RTU….according to customer/project requirements, Our Analysers perform the analysis in 5 seconds, not minutes like GC or fast GC, The Analysis is done exactly by theoretical definition, there is no need to “adjust” or to do “field calibration”, No catalyst at all. This may snuff the flame and damage equipment. 0000395255 00000 n is the molar mass of air which is about 28.96 kg/kmol.
