All Exhaust gas cleaning

Exhaust gas cleaning

The efficient dedusting

Before the combustion exhaust gases are released into the atmosphere, the pollutants they contain must be removed.

Impurities in the exhaust gas can be both solid particles and gaseous substances.

When deciding on the appropriate exhaust gas purification concept, information about exhaust gas quality and quantity must be taken into account.

The lowest residual dust loads can be achieved with electrostatic precipitators, which achieve high separation levels even with fine dust.

The use of bag filter systems makes sense for exhaust gases with very high dust levels.

By combining separation systems, both high inlet dust loads and low residual dust levels can be managed. Combined separation systems that integrate electrostatic, wet, and centrifugal separation achieve separation efficiencies of over 90 %.

Exhaust gas cleaning

Electrostatic precipitator

Electrostatic precipitators are used primarily when there are high demands on the residual dust load. They have high levels of separation, even when it comes to fine dust.

In the electrostatic precipitator, the solids contained in the exhaust gas are charged by spray electrodes. Through the action of an electric field, the harmful particles are transported to the collecting electrode and thus separated from the exhaust gas stream.

The separated particles form a layer of dust on the precipitation plates and lose their charge when these plates are grounded.

Both precipitation plates and spray electrodes are tapped using hammer mills. The separated dust particles fall into the dust bunker due to the mechanical impulse.

Exhaust gas cleaning

Bag filter

Bag filters are able to meet current and future requirements with regard to the required separation levels for particles and other gaseous components in continuous operation.

The solids are separated using textile filter bags, which are stabilized using stainless steel support baskets. The contaminated exhaust gas flows from outside through the filter bags, with the particles being retained in the filter bags.

To clean the filter hoses, compressed air pipes are arranged in front of all hose openings, through which the filter hoses are partially cleaned pneumatically.
