Sealing collar TecHeat®

for petrochemical industry

Tube sealing / pipe sealing / piping sealing / hoses sealing 1% increase in furnace efficiency (*) Reduction of atmospheric emissions of Co and Nox Installation in less than 15 minutes by collar without furnace shutdown or an external service provider Find out more Imperfect combustion implies the presence of unburned fuel in the chamber generating an explosive atmosphere. The O2 rate has a direct impact on the quality of combustion. An explosion (even a small one) inside the chamber will irreparably impact (with a greater or lesser risk) the lyres/tubes (not only in the chamber in question); this explosion (sometimes undetectable and not detected) can cause the extinction of the flames with the chain reactions which are related to it which can lead to an explosion or Fire. The empirical fuel efficiency gain is estimated at 1% for 2% O2 gain in the flue gases The TecHeat® Expansion Collar is a range of static seals specially developed to preserve the integrity of the tube passages at 1000°C and avoid parasitic air inlets which disturb the operation of the installations. Intended for unlimited axial & radial expansion movements, it optimises the combustion process (reduction of fuel consumption), reduces Co and Nox emissions and reduces operating and maintenance costs. Made to measure, it is integrated into the inlet and outlet of tubes, on the radiation and convection part. 1 point fixing: casing of the furnace Sliding sealing Simplified installation, assembly of 2 ½ collars around the tube, mechanically fixed to the ferrules No structural modification required or needed for intervention from external providers Removable for checks, resistant to maintenance washings
