CFD simulations analyze mass flows, heat transfer and associated phenomena, enabling us to:

- quantify the expected effects, including temperatures, air speeds, emissions and pressures; - discover unexpected effects and optimise them; - implement “what if” scenarios; - use animations in order to visualise air flows.

CFD diagram top right – This 3d CFD illustration shows the temperature gradient within the building. In the lower areas where the cold air flows in from the outside, the temperature remains low. The temperature rises as the air moves towards the roof, and its natural buoyancy ensures that the air is efficiently extracted through the natural roof ventilators.

CFD diagram bottom right – This CFD illustration shows the air paths. It enables the designer to establish the best position for the extract ventilators, where they will be free from adverse wind suction or wind pressure effects.

“Because energy is still the essential component for economic growth and because of our limited fossil energy reserves, energy efficient technologies are ever more important. We are now able to make use of the potential to increase energy efficiency.” Andreas Knoll, Product Development Manager at Colt. Colt systems are highly advanced and use efficient technologies, with low initial investment and low running costs. _____

6 c Colt solutions for power plants 7 Colt products & systems The Colt Product Range Wherever possible, Colt will design solutions that make use of natural ventilation, which reduces running costs through the reduced consumption of energy. The many advantages of this solution include no energy

consumption or CO2 emissions, minimal maintenance, silent in operation, self regulating, very low operating costs, ventilators have a long life span and not liable to breakdown. in cases where the design of the building or the client’s requirements do not permit the use of natural ventilation, Colt will use mechanical ventilation to achieve the desired result.

A broad offering for tailored solutions

Colt offers a broad product range befitting the wide demands from the power generation sector. the conditions in a or an energy from waste facility demand rugged equipment. Colt products are fully tested in its own and third party laboratories and highly durable. The majority of them are manufactured under the ISO 9000 series of stand- ards. Colt offers natural and mechanical ventilation systems to remove heat, humidity and contaminants: • Wall/inlet ventilators, e.g. [1] FCO or [2] Universal Louvre 6 • Natural roof/extract ventilators, e.g. [3] EuroCO/Seefire, or [6] labyrinth • All weather natural ventilation module, e.g. [4] Weatherlite Explosion relief ventilator, e.g. [5] Securex • Mechanical extract units, e.g. [7] liberator • Mechanical input units e.g. Coltair • Cooling units e.g. Coolstream evaporative cooling system.

Smoke ventilation units can integrated in the natural ventilation system to ensure safe evacuation and fire fighting and to minimise smoke damage in a fire. Performance and screening louvre 7 systems ensure ventilation while protecting from the rain (see [2] Universal Louvre). Acoustic baffles prevent unwanted noise breakout for low environmental impact while ensuring effective ventilation.
