Particulate filters and SCR systems for CHP plants

Practice-proven after-treatment of exhaust gases by TEHAG

TEHAG / Particulate filters and SCR systems for CHP plants - Reference 1

Decentralised electricity and heat pro­duc­­tion with combined heat and power plants has grown significantly over the past few years. The wide range of dif­fe­rent fuels that are used in these plants re­sult in a variety of different and, in part, increasingly complex re­qui­re­ments for emission reduction in the plants’ ex­haust.


When diesel, biodiesel or plant-based oils are used, both par­ti­cu­la­te matter and gaseous pollutants such as hy­dro­car­­bons (HC), car­bon monoxide (CO), and nitrogen oxides (NOx) must be sus­tain­ably re­duced.

When natural gases are used, slippage of uncombusted gas must al­so be taken in­to account along with the after-treat­ment of ni­tro­gen oxides (NO). The topic of me­tha­ne slip as well as the treat­ment of form­al­de­hyde (CH2O) emissions when biogases, landfill gases or gases from se­wage treatment plants are burnt are also important in this field.


Not least due to the tightening of the thres­­hold values of TA-Luft, but also as a result of regional thres­hold value re­­qui­re­­ments, multi-stage exhaust treat­ment systems are necessary to ensure safe ope­­­­ra­­tion of combined heat and power plants.

With our wide range of products, TEHAG can effectively reduce all pollutant groups found in the exhaust from CHP plants so that you are gua­ran­teed to re­main under the required thresholds. Through a combination of particulate fil­ters, SCR systems and specially coated catalytic con­ver­ters, we can significantly reduce particulate matter as well as ga­se­ous pollutants – at times, even be­low the limit of detection.
