Dispersion control: industrial stacks for heavy industry
Freestanding single- and multi-flue stacks and the steel structures that carry them, engineered for wind, seismic and thermal loads. Specified in-house, validated by structural modelling, manufactured in our own production facility.
Stacks engineered for load and dispersion
Axces industrial stacks discharge flue gas safely and to code, sized against dispersion requirements and the structural loads of the site, not a catalogue height.
Every project starts with the site data: flue gas flow and temperature, the required discharge height, and the wind, seismic and thermal loads the structure has to carry. From there our engineers select a freestanding single- or multi-flue arrangement or a supporting steel structure, model it, and confirm it against the relevant codes before fabrication begins.
The range spans freestanding single-flue and multi-flue stacks and the bolted steel structures that support them, all built to the same engineering discipline and integrated with the surrounding plant.
Structural and wind modelling
FEA and wind-load analysis to confirm stability, vortex-shedding response and fatigue life before manufacture.
In-house structural design
Single-flue, multi-flue and support structures designed to wind, seismic and thermal loads.
Survey and erection
Site survey, erection support and post-install inspection of the completed structure.

A recent stack project, paired with technical guidance from our knowledge hub.
Case study · Power Generation
48 exhaust systems for a 450 MW UK power plant
Forty-eight complete exhaust systems (ducting, silencer and chimney) routing 95 gas engines into 48 stacks at 69 dB(A) at one metre, CE marked, fully designed and produced to EN 13084-7.
Knowledge hub
How emission limits set stack height
How dispersion and ground-level concentration limits drive the discharge height of an industrial stack, linking emission compliance to structural design.

In-house structural engineering
Stacks and structures are specified by our own engineers against site loads and codes, not picked from a catalogue.
Wind and FEA capability
Wind-load and FEA analysis let us confirm stability, vortex-shedding response and fatigue life before manufacture.
Own production in Poland
Fabrication in our own facility keeps quality, lead time and weld traceability under direct control.
Power and EPC track record
Delivered freestanding stacks and steel structures on power and EPC projects, erected to schedule.
How an Axces project runs
Survey and data
We capture gas flow, temperature, discharge height and the wind, seismic and thermal loads the structure must carry.
Structural modelling
Candidate arrangements are modelled with FEA and wind-load analysis and checked against the relevant codes.
Design and manufacture
Drawings are signed off, then fabricated and inspected in our own production facility.
Install and verify
We support erection and inspect the completed structure on site.
