Post-mix burner and use of same for generating a flame curtain, the burner having a longitudinal central dividing wall () terminating in a wall head () towards the burner top (), an oxidant inlet compartment () and an oxidant outlet compartment () on a first side of the central wall (), a fuel inlet compartment () and a fuel outlet compartment on the opposite side of the central wall (); the wall head () presenting a first set of oxidant outlet passages () and a second set of fuel outlet passages () terminating respectively in first oxidant ejection openings () and second fuel ejection openings () in an ejection surface () at the burner top (), the oxidant and fuel ejection openings () each extending in the longitudinal direction along the ejection surface ().

Compact flame-curtain burner

Installation for analyzing an atmosphere

The invention relates to a process for preparing a heat treatment atmosphere by a catalytic reaction in a catalytic reactor (16) between a first gas mixture (12) containing oxygen and a second gas mixture (26) containing a hydrocarbon, characterized in that the catalytic reactor is arranged in substantially vertical position and in that the reaction mixtures are introduced into the catalytic reactor through the bottom (19) of the reactor with recovery of the heat treatment atmosphere resulting from the reaction at the top (20) of the reactor.

Process and installation for preparing a heat treatment atmosphere

An installation for monitoring an apparatus for generating atmospheres. The installation includes a measuring device for measuring at least one parameter representing the actual operation of the apparatus, an evaluator for evaluating the drift of each representative parameter over time and a trigger for triggering an intervention on the apparatus as a function of the drift before values of each representative parameter reach predetermined critical values.
