The first test conducted by a testing crew is the dirty air traverse. That test uses the same sampling points when measuring velocities in the pipes. By measuring the true velocity flowing through the pipe, guessing an unknown velocity, as required by the ASME test procedure, is eliminated. After the dirty air velocity test is completed, the ...
WhatsApp: +86 18203695377The clean air probe velocity kit is focused on measuring air flow in coal pipes or mill inlet ductwork. It is used to determine the isokinetic particulate sampling rate for the the ISO 9931 and ASME PTC test methods. ASE offers a different velocity measurement system (the 3DDAS) for general purpose duct flow measurements

WhatsApp: +86 18203695377Air Emissions One of the key environmental challenges is control of air emissions from the recovery cycle. The main concerns have historically been particulate, TRS (total reduced sulphur gases, mainly H2S), SO2, and recently NOx. Now, there is increasing focus on other gases, such as HCl, NH3, CO, methanol, and other volatile organic compounds.
