Purenviro provides chimneys for flue gas, odor and emissions to air. We supply complete projects including engineering, bases, production, installation and commissioning. 

When do you chose a chimney? 

Chimneys should be part of the overall strategy to minimise the impact of emissions to air. No abatement techniques can provide 100% efficiency. Teh remaining emissions should be diluted in chimneys to avoid nuisance. Chimneys are part of the BAT (best available technique) for most industry sectors.

Features

Most important advantages with chimneys: 

 

 Robust solutions

 Low energy consumption

 Easy maintenance 

 Instant start up effect 

 Height adapted to optimal abatement 

 Small footprint

Applications

Chimneys are used in a wide range of industries. Our experiences include dispersion of smoke, flue gas and odor. 

Biogas

Chimeys are used at biogas upgrading plants

Bio energi

Chimneys are used to disperse flue gas from bio energy plants 

Flue gas

Flue gas and smoke for facility boliers and energy plants normally require dispersion from chimneys

Combined heat and power plants

CPH plants running on biogas, pellets, oil, coal or gas will require chimneys for final flue gas treatment. 

Alternatives

Alternative versions

We supply chimneys with capasities up to 400.000 m3/h, temperatures up to 550oC and gas velocities of 25 m/s. All our chimneys are produced by SSM
