Hot Air Traverse Test in Coal Mill-2B Background A gap of 8-10 T/Hr was noticed between P.A Flow UCB indication and 'Air-Fuel' ratio test measurement. It was expected phenomenon because of change of venturimeter characteristic due to wear of venturimeter 'throat' which in turn was due to its continuous use since first commissioning of unit on 01/02/1994. Such venturi would produce lesser DP ...
