CL.AIR Exhaust Treatment System

Exhaust Treatment System

In the past, meeting the technical limits on air quality control for carbon monoxide emissions meant significant efficiency losses, especially in the case of critical gases such as landfill gas and sewage gas. The CL.AIR (CLean AIR) exhaust treatment system resolves this problem, making it possible to achieve high specific output and efficiency coupled with minimal emissions.

Features & Benefits

The CL.AIR system is designed for the post-combustion of engine exhausts. After the exhaust gas has been heated to a temperature of about 1,472 °F (800 °C), the uncombusted hydrocarbons and carbon monoxide oxidize to form water vapor and carbon dioxide. Since no catalytic reactions take place during the thermal treatment of the exhaust, this process is particularly well-suited for use with diverse biogases and special gases for which catalytic converters either cannot be used, or are used only to a limited extent.

The CL.AIR system reduces carbon monoxide, non-methanic hydrocarbon, methane and formaldehyde emissions to levels well below the technical limits set for air quality.

Ordering Information

The CL.AIR system is based on a regenerative heat exchange, and consists of a reaction chamber holding two scrubbers and a switching unit. At a temperature of around 986 °F (530 °C), the exhaust gas flows from the engine via the switching unit into the first scrubber, where it is heated to around 1,472 °F (800 °C). In the reaction chamber, the exhaust gas reacts with the oxygen it contains, oxidizing carbon monoxide and HC to produce carbon dioxide and water. The exhaust gas emits heat again as it passes through the second scrubber, and at a temperature of around 1,022 to 1,058 °F (550 to 570 °C) it reaches the switching unit, which directs it to the smokestack or a downstream waste heat boiler.
