METHOD AND DEVICE FOR REDUCING FORMATION OF PARTICULATE MATTER IN GAS STREAMS

摘要

A method and device for the reduction of particulate forming vapors in gases, the method comprising passing the gas stream through at least one channel (12) that has a wall temperature that is lower than the condensation temperature of the vapor, the at least one channel having a hydraulic diameter (Dh) satisfying the condition that Dh<[24/(Npido)]1/2, where N is the number of nuclei present in the gas stream and do is the initial diameter of the nuclei.
