Coke Ovens
For more than 35 years, FIBS has provided coke plants with technologies dedicated to the preventive maintenance and curative repair of coke oven refractories, as well as a unique process for the reduction of air emissions (cross-leakages). These technologies are fully engineered in-house. Since 2020, FIBS technologies have been regularly applied in Indian coking plants with the highest satisfaction.
Ceramic Welding of Coke Ovens : By Products / Non Recovery
Ceramic welding of coke ovens is a strategic technique for the preservation of coke ovens and for air emission control.
Since 1992, FIB-Services International has offered a genuinely unique ceramic welding technology, developed by FIBS in close collaboration with operators and R&D centers.
This collaboration between experts in coke oven preservation has enabled FIBS to develop a ceramic welding technology with the following advantages:
-
Equipment is safe, compact, easy-to-use, lightweight, robust, and low-maintenance.
-
Ability to weld all parts of the coke ovens (chamber walls, charging holes, regenerators, sole flues, waste gas boxes, etc.).
-
High-performance materials for ceramic welding: long life, low rebound rate, and easy application.
-
Different material grades: silica-based, low-temperature silica-based, and alumina-based.
Endoscopic Survey of Coke Ovens : Regenerators, Coking Chamber, Risers, Flues
Endoscopes are regularly used by coke plants to assess the condition of the refractory lining, detect leakages, identify blockages in the heating network, and identify all other types of defects.
Furthermore, endoscopy is used to support complex repairs, such as ceramic welding in the deeper parts of the oven.
Thanks to a full range of endoscopes (flexible, rigid, and semi-rigid, in various dimensions), we are able to inspect the following parts of the coke oven battery:
-
Coking Chamber
-
Charging Holes
-
Heating Flues
-
Gas Risers
-
Horizontal Gas Channels
-
Sole Flues
-
Regenerators
-
Waste Gas Box
Liquid Dusting for Treatment of Microcraks (Air Emissions)
Air emissions and environmental care are important factors in coke production. Air emissions from the coking process have various origins, including cross-leakages between the coking chamber and the heating flues. When these leakages are too narrow, it is very difficult to close them individually with ceramic welding. FIBS has engineered a genuine process that allows for the global sealing of microcracks.
The process consists of the injection of approximately 2 liters of liquid material (which is not a water-based suspension of silica) into the coke oven chamber. The material ignites and creates a cloud of new silica particles (amorphous = no risk to health) that are pushed by the pressure release of the reaction through the cracks, resulting in the complete sealing of the coking chamber. The application takes only 5 minutes.
