Single source service solutions along your entire plant life cycle

360° Service - increasing efficiency, conserving resources, reducing emissions

Repairs, inspection and maintenance of coke oven batteries

With 150 years of experience thyssenkrupp Industrial Solutions offers the whole scope of services for a straight operation, increase of production, minimization of emissions and to prolong the life time of the batteries:

Inspections of coke oven batteries

Regular inspections of the coke oven batteries are indispensable in order to identify impermissible deformations. We combine our digital and technical competences and use the information to create measurable added value for our customers.

Heating flue/wall inspections

Waste gas measurements/analysis

Inspection of mechanical equipment (wall protection plates, doors, bracing system)

Inspection of coke oven service machines

Thermography

Heating flue/wall inspections

An annual inspection of a coke oven battery is necessary to identify existing problems or defects which will cause problems in the future. To prevent from this, the inspection result will help to determine necessary next steps like maintenance, repair or refurbishment of parts of the battery. This will prolong the life time of the battery and secure the production of coke.

Inspections of the refractory such as:

Inspection of heating walls for cracks, surface damages, deformed areas of brickwork, oven sole and cover bricks

Damaged corbel areas and regenerators walls

Blocked heating flues

Restricted gas flow through the regenerators

Cross-leakages from oven chamber to heating flue

Over expended and grown brickwork at the oven top

High oven top temperatures

Inspections of the mechanical equipment such as:

Misadjustment or inoperative bracing system

Bent/damaged buckstays, supports, tie rods etc.

Any kind of damages to springs, pressure bolts etc.

Malfunctions of the oven closures like oven doors, door frames, charging holes etc.

Malfunctions of the heating system like gas/air boxes, reversing system, gas distribution etc.

Providing a customer-centric interface

Your advantages:

Identify anomalies in the refractory wall of a coke oven plant by
Systematically capturing images and classifying anomalies

Advising the maintenance team with possible remedial actions

Regular maintenance in coke oven batteries

Due to the usual tear and wear during regular operation, the integrity of the coke battery and the by-product plant can derogate and needs to be adjusted with different measures on a regular basis.

Referring to the refractory brickwork of the battery, leakages due to cracks, leaky joints and damages to the brickwork can occur. Regular maintenance work will prolong the life time of the heating walls until bigger repair works are required.

Often graphite deposits need to be eliminated, doors need to be sealed and means like gunning and ceramic welding can close joints and cracks.

With regard to the mechanical equipment the bracing system shall be adjusted twice a year.
Also steel structures should be inspected to identify defects or probably corrosion.

Based on a regular inspection services thyssenkrupp Industrial Solutions offers to prepare maintenance manuals and can execute the works.

Maintenance of the bracing system

Assessment of the integrity of the plant (optionally supported by means like 3-D scans and drone measurement)

Design/material quality improvements

Fabrication and supply of high quality materials in shortest possible time

Highest quality standards

Dismantling and assembly on site

Regular adjustment of the bracing system

- Adjustment the springs to maintain the required anchoring forces

Repairs/ renewals

With increasing age of existing batteries, damages occur due to high temperatures and mechanical stress of the refractory block. Production capacity is effected. thyssenkrupp Uhde is able to prolong the lifetime and to reset the production to the design capacity by using different systems to rehabilitate the refractory installations under the conditions of a producing plant.

thyssenkrupp Uhde is, with its worldwide service teams, in a position to refurbish the refractory block of the damaged heating walls in line with new technologies. Tailor-made integration into the existing plant minimizes production downtimes and extends battery life.

Scope of work

Creation of customized revamp concepts

Reengineering of the existing design

Selection and quality-controlled delivery of materials

Execution of the refurbishment

Management of the entire repair area, including heating management during the refurbishment

Refractory part

Due to the usual tear and wear of the refractory brickwork during regular operation, and very often also due to damage caused by improper operation or the failure to carry out regular maintenance work, the condition of the refractory brickwork deteriorates and the following problems can occur:

Damage to the oven chamber refractory brickwork, such as spalling, cracks, deformed and/or collapsed brickwork, which could cause problems during operation (coking process, machine operation, emissions)

Leaks from the coke oven chamber into the heating flues due to cracks, leaky joints and damage to the brickwork increase emissions and change the heat distribution and combustion

The renewal of heating wall refractories requires special repair techniques and experience in all regards (engineering, material supply, construction work and heating control) as the remaining part of the battery must be kept hot and the new brickwork must be integrated into the existing brickwor

The scope of renewal must be defined based on the condition of the coke oven battery and the location of the main damage, for example:

Full renewal of heating walls (through wall repair)

Renewal of heating wall end flues (end flue repair)

Renewal of regenerator walls and corbel areas during wall repairs

Renewal of the oven top refractories (oven top repair)

Renewal of regenerator internals (re-checkering)

Your advantages:

Prolongation of the life cycle of a battery

Repair during operation of the battery (hot repair)

Minimum production loss

Recovery of the battery performance

Adjustment of heating system

The adjustment of a coke oven battery heating system is an important aspect for the operation. With the adjustment of the heating walls, the draft of the stack or waste gas boxes, the environmental pollution can be reduced to a minimum. Furthermore the steady temperature distribution of the heating walls will ensure a good coke quality and reduce the consumption of gas.

thyssenkrupp revamp teams have specialized engineers and technicians based in Germany as well as worldwide. These teams are experienced with the commissioning of all types of coke oven batteries.

High quality of the product, the full volume of the coke production as well as the compliance with environmental regulations will be achieved with our services.
