1. Our ESPs deliver a high degree of separation.
2. Not sensitive to dust load fluctuations (even with fine dust, flying sparks or overheating!)
3. Our ESPs are modularly designed and are capable of separating gases at up to 300 °C with an efficiency of < 5 mg/Nm3 clean-gas dust concentrations.
By using static electricity, an ESP (electrostatic precipitator) removes fine particles like ash, dust, smoke and soot from a flowing gas. During the filtration, gas flows are barely affected and therefore ESP’s do not pose a threat to the efficiency or flow of a plant’s operation.
As can be seen on the picture, the gas flows through the ESP’s housing and simply must pass an area with electrodes (which sometimes are just simple metal wires or plates). There, pollutants are caught and stored on the plates or wires themselves. After some time, those plates or wires get cleaned off and the pollutants fall down to hoppers where they get taken away for further processing or disposal.
Another advantage of this technology is it’s energy efficiency when compared to wet scrubbers. While the latter needs to apply energy directly to the whole flowing fluid medium, an ESP only has to use energy on the particulate matter itself and is therefore much more energy-efficient. Depending on the application, an ESP can be the better choice for your situation. Of course this where we come in and can offer you one of our services. We can help you determine the right technology by considering each and every advantage or disadvantage when selecting a filtration method for your business. There are many factors that must be considered, because many different parameters (mainly in the “gas cleaning”-phase after the combustion process) have a direct influence on the separation efficiency
An electrostatic precipitator (ESP) may require a major upgrade or replacement due to present and future emissions considerations. For example: Your current ESP might not meet outlet emissions requirements. A low cost option to consider for compliance strategy is the conversion of your existing ESP casing to a pulse jet fabric filter ( = baghouse).
The major advantage of baghouses is their particulate collection efficiency, which typically reaches 99% or more, even when particle sizes are comparatively small. Whether baghouses or electrostatic precipitators are a better choice for your situation, depends on your plant’s individual requirements and situation.
