Steuler your experienced partner for brick linings
Whether it involves pickling or acid regeneration plants, vessels, flue gas ducts, reactors venturiscrubbers, autoclaves or absorption towers – Steuler are the experts in both theory and practice.
As a specialist in the field, Steuler offer custom solutions, drawing on a wealth of original technical knowledge.
Withstanding the most extreme demands
Due to exposure from a range of factors, brick linings are subject to extreme stresses:
Chemical stress
- Chemical attack by media in liquid, gaseous or solid states
Thermal stress
- Temperature level and temperature distribution
- Temperature differences between the individual layers of the brick lining and the environment
- Thermal cycling
- Different coefficients of thermal expansion of lining materials and structure
Mechanical stress
- Pressure ratios
- Vibrations
- Abrasion
- Impact stress
- Traffic
Protection against extremes
For decades now, the liquid-phase oxidation process has been across the mining industry amongst others to remove sulphur from ores.
Specifically developed brick linings are a tried-and-tested way of protecting the process equipment used, such as autoclaves, flash vessels and quench towers, against the extreme stress profiles
encountered.
When designing the lining, its low elasticity within a relatively high elasticity steel vessel must be taken into account.
Steuler has the data and equipment necessary to calculate the thermal expansion as well as the linear thermal expansion and chemical expansion of the brick lining.
Abrupt temperature changes and decreases in pressure do not occur under normal operating conditions, but their effects should be accounted for in the engineering analysis.
Finite element models and research and development of the brick lining materials are the way to successfully master the complex engineering of pressure vessels.
Flue gas treatment
High gas temperatures, sulphur compounds, phosphoric acid and highly aggressive hydrofluoric acid require suitable lining materials and experienced detail engineering got the various stages of the plant process and critical areas, such as
inlets and outlets.
Where fluoride compounds and hydrofluoric acid are encountered, carbon bricks can be used to reliably protect against chemical attack and higher temperatures.
As a turnkey supplier, Steuler takes care of all the engineering work, material delivers and installation work.
