TEKE - Power Plant Heat-Exchanger Surface Cleaning

TEKE - Power Plant Heat-Exchanger Surface Cleaning

TEKE is a service company that specializes in metal and concrete surface coating, cleaning power plant heat-exchanger surfaces and construction reinforcements. We provide the following services:

• Concrete and metal surface coatings for vacuum and centrifugal pumps, screws, basins and tanks, flue gas equipment and floors
• Almost dust-free Sponge-Jet® blastings before coating for paper machine frames, turbines (for cleaning) and other equipment for which dust is a problem
• TEKE cleaning technology (TCT) for boilers and power plant elements, including superheaters, burning air preheaters, water preheaters and precipitators
• Carbon fibre reinforcements

Power plant boiler-element cleaning

Burning wet biofuels and forest residues for example causes a build up of deposits on top of power plant boiler-elements. This reduces the efficiency of the plant and in the end it forces the plant to shutdown for cleaning.

Power plant heat-exchanger surface cleaning

The cleanliness of power plant heat-exchange elements is therefore a vital factor for economic power production. Using TCT, we have developed a service concept for cleaning power plant boilers and their heat transfer components with special blasting system.

We specialise in power plant heat-exchanger cleaning for surfaces in superheaters, air and water preheaters, precipitators and other induced or natural draught systems.

Metal and concrete surface coatings

TEKE has repaired and protected concrete, metals and other basic materials for over 15 years. We provide a wide range of metal and concrete coatings to protect against abrasion, erosion and corrosion, as well as chemical-attack-resisting metal and concrete coatings. By using carbon fibre structure composites, for instance, we reinforce constructions made of concrete, wood and metal.

TEKE's coatings can be modified with features that increase its strength, chemical resistance, self cleaning and antibacterial properties.

Composite, nano-reinforced, rubber and wear and temperature-resisting coatings

TEKE provides the following surface coatings for metals:

• Various composite coatings used to protect against corrosion, erosion, abrasion and chemical wear
• Tailor-made nano-reinforced coatings
• Various rubber coatings to protect against friction, corrosion and abrasion
• Wear and temperature-resistant inorganic coatings

Concrete surface coating techniques

TEKE supplies the following techniques of surface coatings for concrete:

• Impregnation
• Crystallization coatings and waterproofing
• Anti-carbonization
• Epoxies
• Nanostrengthened epoxies
• Polyurethane
• Rubberized asphalt
• Injecting
• Cement-based, polymer reinforced repair mortars
• Polymer quartz composite coatings
• High strength concrete (350MPaN/mm²)
• Temperature-resistant high strength concrete (400°C -1,200°C )
• Composite for joints
• Carbon fibre structure composites

Carbon fibre laminate reconstruction

Carbon fibre composite plates and bars are used for the reinforcement of structures. Using special adhesives, they are attached to plane surfaces in plates and bands.

The weight of carbon fibre laminate is only one fifth of steel, but it is several times stronger. It provides a safety belt that increases the strength of constructions when attached into it.

Waterproofing crystallization coating

Wet concrete is a problem in many industrial constructions. Waterproofing with crystallization is a solution for many applications.

Dust-free blasting

Almost all of TEKE’s work is done using dust-free blastings, which gives an excellent surface profile or purity degree. In commonly used sandblasting, dust is spread to the environment. In the method TEKE uses, blasting sponges collect the dust so it is not spread. The profile of the blasted surface is checked and optimized to be the best for the particular application.

Rapid-setting repair mortar reinforcement

MSS 470 is TEKE’s rapid setting repair mortar designed for overhead, vertical and light duty horizontal applications. It consists of a blend of portland and other hydraulic cements, silica sands, lightweight filler and a styrene acrylic copolymer powder.

MSS 470 is a quality controlled repair mortar which exhibits extremely rapid development of physical properties. The presence of the copolymer ensures an excellent bond to most surfaces and improves such characteristics as impermeability, flexural and tensile strengths.

Impermeable flooring composition reinforcement

MSS 6020 V is a high performance impermeable flooring composition specifically designed to give resistance to impact and abrasion in chemically aggressive environments. It is easy to apply, forms a coving where required, and provides a jointless, easily cleaned topping, which has a degree of slip resistance.

MSS 6020 V consists of a blend of a low viscosity epoxy binder, silica aggregate of optimum grading and an optional light fast pigment. MSS 6020 V has a maximum grain size of 1mm and can be applied down to 3mm thickness on horizontal and vertical surfaces.

From our Nordic originating network, we sell the products mainly under our own trademark, MSS. We have a total turnover of more than €50 million.
