INDUSTRIAL CHIMNEYS – POLYKAMIN

Large industrial chimneys of brick, concrete or steel also fall victim to corrosion, irrespective of whether their boiler system is natural or forced draft. The temperature of the flue gas in these chimneys is usually under 160 °C, but may go up to 240 °C for short periods. Industrial chimneys have the following dimensions: diameter 900-6000 mm, height: 30-120 m.
These cannot be lined or rebuilt using Furanflex® technology.

KOMPOZITOR Kft. has developed a new technology and material with which independent, self-supporting composite material chimneys can be constructed with diameters of between 1000-3000 mm. The advantage of a composite chimney is excellent resistance to corrosion.
The manufacturer gives a 30-year guarantee with its Polykamin brand-named composite industrial chimneys.

In all cases industrial chimneys demand individual planning as their construction is complex.
Due to this these chimneys are designed, manufactured and installed by KOMPOZITOR Ltd.
KOMPOZITOR Ltd. installed such a chimney in Hungary in 2005 at the ONYX hazardous waste incineration plant and in 2008 for BÉM Zrt's Ore, Mineral and Waste Utilisation Plant.

DOROG

The background of the POLYKAMIN ONYX chimney
After eight years of operation the steel chimney of the hazardous waste incineration plant had corroded, even though it had a 5 mm thick internal rubber lining. The management of the plant chose the POLYKAMIN solution.
The data of the Polykamin chimney which we installed in 2005:

Internal diameter	1250 mm
Wall thickness	25 mm
Length of vertical chimney tube section	40.7 m
Mass of vertical tube section	9.3 tons
Mass of lower curved section	0.7 tons
Diameter of drop catcher	2500 mm
Mass of drop catcher	1.7 tons
Amount of condensation water flowing back	4.000 l/hour
Guarantee against corrosion defects	30 years

After three years of continuous operation the internal surface of the Polykamin tube is faultless. The construction process of the Polykamin chimney at Dorog can be seen in the FILMS menu.

SAJÓKERESZTÚR

The background of the POLYKAMIN BÉM Zrt. chimney
The plant operates a steel chimney, its height is 60 m and diameter 6.5 m. Flue gas originating from metallurgical processes (110 °C) is emitted from the chimney at a very low speed.
For environmental protection reasons it became necessary to increase the speed and height of emission.
The plant wished to solve the issue using POLYKAMIN technology in the following way:

Truncated cone   Polykamin chimney tube   Lifting on the POLYKAMIN chimney   The POLYKAMIN chimney during installation

A truncated cone was fitted to the upper edge of the existing chimney: Lower diameter 6.5 m Upper diameter 2.5 m Height 4 m Material Resin composite Mass 5 tons A vertical tube was fitted to this truncated cone: Diameter 2.5 m Length 18 m Mass 8 tons Material Resin composite New emission height of flue gas 60+4+18= 84 m Flue gas speed increase 6.8-times The construction of the POLYKAMIN chimney in Sajókeresztúr can be seen in the FILMS menu.
