Gas Filtered to Avoid Ammonia Salt Damage

Formation of ammonia salts, typically taking place in DeNOx processes, block and damage lines. As a countermeasure, Bühler Technologies, distributed by DRM Technic (UK), has developed a DeNOx probe, which combines their reliable gas probe technology with integrated salts and aerosols washing. Sample gas enters the probe, which is heated to maximum 280°C, filtered and subsequently directed downwards into a glass vessel containing glass beads. The formed condensate including the ammonia salts are removed via a peristaltic pump whilst the gas continues to the heated line. Due to the removal of ammonia, standard gas conditioning equipment can follow thereafter. A weather protection housing and frost protection are included as standard to permit external operation.
