System for the use of catalytic radiant panels for heating vacuum chambers

摘要

The invention relates to a system for the use of catalytic radiant panels for heating vacuum chambers by radiation or by radiation and expansion of flue gases. The system consists of a channel 4 supplying oxygen or atmospheric air in the region of the radiating face of the radiant panel 3 via a regulating valve 6 which controls the flowrate as a function of the flowrate through the valve 5 of the gas/primary-air mixture and of the desired expansion of the flue gases into the vacuum chamber via the flue-gas valve (register) 7. <IMAGE>
