Hi,

We use cleaned Coke oven gas as fuel for our Cold Rolling Mill complex plant in Jamshedpur. We find that the burners of the batch Annealing furnaces and the Hot dip Galvanising lines are getting choked with a brown deposit, very fine in Size. The powder is brown in color and has the following analysis:

Naphthalene: 38%
Tar: 56%
Ash: 2 %
Moisture: 4%

The cleaned oke oven gas that we use analyses as follows:

H2: 56%
CO:9%
CH4:20
CmHn:2.4%
O2:0.8%
N2: 9%
Tar: Negligible
Naphthalene: 117.1%
H2S:0.19%
NH3:17.3%

What should be the right composition of Coke Oven gas for such applications?

Which are the other plants using only Coke Oven gas in their steel plants ?

Is this deposit harmful and at what frequency should the burners be cleaned ?
