NOx control

MIRATECH’s CBL catalyst housing for a SCR system is a lower cost unit designed for diesel or natural gas engines.  The CBL housing unit houses 450 mm long catalyst blocks and can support two blocks (900 mm) if needed.

Where NOx control is a challenge, MIRATECH delivers the best SCR system, service, and product support.  The MIRATECH SCR systems work in two efficient stages: the NOx Reduction Stage and the Oxidation Stage for CO and HC reduction. Both stages work together, drastically reducing harmful emissions to satisfy the strictest regulatory requirements.

The CBL housing is designed for the NOx Reduction Stage and houses the SCR catalyst.  This is where the exhaust that has been injected with ammonia (whether injected directly or formed from urea) reacts with NOx to form harmless water and nitrogen.

Its carbon steel housing has flanged inlet and outlet connections, so that it can be easily bolted into the engine exhaust system. Lifting lugs and mounting feet are also provided for ease of installation. An access door is provided for loading the filter blocks, and an additional access door and ports are provided for filter cleaning. Instrumentation ports are installed on the inlet and outlet for monitoring the pressure and temperature differentials across the filter.
