XI. AGGLOMERATION

2012-8-14  Of all the agglomeration processes, only the continuous sintering strand and pelletizing are now of any significance. The reasons for the failure of other processes are: 1. High fuel cost due to thermal inefficiency 2. Mechanical unreliability leading to high maintenance costs and low availability 3. Liability to serious operating problems 32

Dust Agglomeration in an Electrostatic Precipitator

2021-6-15  ABSTRACT Dust agglomeration in an electrostatic precipitator (EP) during the sintering process taking place in an ironmaking plant was investigated. The dust agglomeration in the high sulfur flue gas dust hopper of the EP was very serious and did affect the removal of the dust from the hopper. The size of the agglomerate ranged from approximately 30–50 cm and was found to exhibit strong
