Lime Kiln Linings

Rotary lime kiln presents a very abrasive, thermally stressed environment. The refractory linings must be able to withstand chemical attack from fuels and raw materials, changes in temperature as well as mechanical stress from rotating elements.

Soda Recovery Boilers

Refractory materials are used in soda recovery boilers to protect the tubes, i.e. to prevent the tubes from coming into contact with soda melt.

The refractory materials that are used are some form of castables. The castables must be able to withstand contact with soda melt at the temperatures existing in the boiler without reacting or being destroyed by the soda. That is to say that the castables must have good resistance to alkali.

Our refractory solutions are listed on the table below.

Multi Fuel Boilers

Boilers and furnaces are exposed for thermal stress various atmospheres. The refractory lining protects boilers/furnaces for high temperatures, wear and alkali attack.

Höganäs Borgestad has chosen the best quality material suitable for both Soda Recovery Boilers and Power Boilers, to make handling of our and the customers’ stock as efficient as possible. This also reduces the risk that wrong material is used. Our design is the best on the market today, both in terms of cost efficiency and quality.

Extremely high quality materials with specially developed properties, such as enhanced resistance to thermal shock and excellent resistance to sulphur and alkalis and proven energy saving designs, are features of Höganäs Bjuf grades, which, in combination with proven installation technique, guarantee the required availability of the plant together with the longest possible service life of the lining. Service and maintenance are a natural part of our offer. By servicing your plant regularly we can make sure that the furnace works optimally in order to prevent unplanned stops and thereby reduce maintenance costs over the long term.

Höganäs Borgestad will take care of all your refractory needs, from project stage to the final installation and documentation.

Sulphur Burners

Höganäs Borgestad has a great deal of competence and knowledge in the field of sulphur burners. We line many different types and sizes of Sulphur burners for, amongst others, Chellchem Nobel Industries Sweden, which supplies sulphur burners worldwide.

We carry out the installation of both sulphur burners and cooling towers including cooling tower connection pieces, in which the cooling tower can be lined with both refractory material and acid-resistant material, dependent on the type of sulphur burner.

We use well-proven installation techniques and materials.

Priming: After the shell plate has been blast-cleaned, all plating is coated with a primer solution comprising a mixture of HVKD powder and potassium silicate. This protects the shell plate against corrosion.

Material: The fire bricks used are Bjuf SX and the cement Höganäs H-15. If either or both of these are not available then bricks and/or cement of similar quality are used. Conventional castables are HÖGANÄS GUN CC 652 or HÖGANÄS CAST LC 40 AR. There are also other alternatives of similar quality available.

Prefabricated Modules: Nozzle bricks and other specialised bricks used in kilns are produced at our prefabrication department.

Incinerators

We use well-proven installation techniques and materials.

Acid-proof linings

In general, an acid-proof brick should exhibit a high degree of acid resistance, have a high density, high resistance to abrasion and high compressive strength. Brick work that is exposed to temperature changes must be built of bricks that are able to withstand such stresses and strains. To choose the right mortar and tiles is the most important thing for an acid proof lining.

Bleaching Towers

We use acid-proof ceramic bricks. This acid proof brick could be used in lining of containers such as bleaching towers, digesters, cooling towers, pickle tanks, reaction/absorption towers, acid tanks, but even acid-proof floors where the mechanical stresses are large. We have special shapes for cone parts and top parts. We have two kind of mortar for bleaching towers, one for low temperature and one for high temperature. The primer we use is based on vinyl ester. For the top part we have a new design to be able to protect the steel against corrosion.

Sulfuric Acid Tank

Here we use the same type of materials as in the bleaching towers. This bricklaying design is the best both in regards to quality and economy.

In places where there is acid , hot water, salt, bacteria etc., i.e. media that cause problems for concrete or steel and are difficult to clean away, we always use acid proof lining. The type depends on the media inside the tank. If you have problems with bacteria, it is difficult to clean the concrete. Here we use glassed tiles, which are easy to clean.

Floorings

Here we also use acid proof lining. For protection we use extruded tiles. These unglazed tiles can be used for both floors and walls. The properties of these tiles make them particularly suitable for floors that require durability, resistance to chemicals, ease of cleaning and a non-slip surface, e.g. in industrial facilities, chemical factories, dairies, breweries and warehouses, laundries, boiler rooms, fire stations, etc. The mortar we use displays excellent resistance to acids and alkalis in higher concentrations, as well as oxidizing media, greases and oils.
