Types of Pollution Control

Pollution Control Systems

Our incinerators are designed to produce the lowest emissions possible. In some countries you will require additional PCS (Pollution Control Systems) to meet with local limits and thresholds. Our range of pollution controls enables us to offer the right solution every time.

Our standard incinerator range is designed in a way that all exhaust gas has to pass through a secondary burner for complete re-burn of harmful gas components. Exhaust gases are then retained for a period of time at a high temperature (850 – 1200°C, depending on the application). This is what we call ‘Basic’ pollution control.

Dioxins, furans and similar gaseous components are only destroyed by :

• Homogeneous high temperature (> 850°C)
• Excess of oxygen (>6 %)
• Sufficient residence time at high temperatures

All our incinerators are designed to ensure all 3 conditions are met as a minimum.

The three conditions above prevent dioxins from “cracking” into smaller but reactive dioxins, which can reform into new dioxin molecules, especially in the presence of heavy metals which can act as catalysts. (Reformation and “de novo” formation).

In some cases and in certain countries this will not be enough to satisfy local regulations, so additional gas cleaning equipment is required – such as one of the following:
