Into the tail flue of fly ash due to the low temperature, has a certain hardness, so primary heating surface with flue gas exhaust pipe, the wear and tear on the wall.
A precise calculation of acid dew-point is very important for design of utility boilers, flue gas sulfur removal and tail heating surface transformation.
