In the stand pipes, which are the only evacuation point of
the raw gas released during the high temperature coking of the
coal, the section reduction occurs due to the carbonization and the
problem of degazing of the raw coke gas is experienced. This leads
to an increase in the internal pressure of the raw gas in the furnace
and emissions to the doors, which are the weakest points for sealing.
It also leads to energy losses depending on the amount of leakage.
The raw gas passing through the vertical chimneys is 900 degrees
and it is isolated with fireclay bricks to protect the metal parts. In
this improvement, high-alumina castable mortar is used instead of
fireclay bricks. This has resulted in a reduction in emissions and
maintenance costs.

During the life of a coke oven many types of damage
can appear which affect the productivity of the process and
production. To keep coke oven batteries in service for many years,
various methods of repair (gunning, ceramic welding etc.) applies
in different periods. Erdemir Coke Oven Plant Batteries has
repaired via fused silica modular bricks since 2009. Each step of
hot repair has been improved in cooperation with repair company.
The Fused silica modular brick method using less than 10% of
conventional shapes, has enabled rapid push to charge down times.
By using zero expansion brick after repair work it doesn’t needed
complex heating regime and long heating time. During repair time,
less production loss, less manpower needed are biggest advantages
of this method. At last repair, before charging of repaired oven,
oven sole repair has done first time by using self-leveling material.
Self-leveling repair method is rapid, smooth and easy way of the
oven sole repair.
