<p>#CMT# #/CMT# The heating cartridge (9) has air treatment chambers (6-8), and a heat-generating material (2) provided in an interior of one of the air treatment chambers (7). The heat-generating material is granular potassium superoxide. Temperature of 40 to 60 degrees Celsius is produced during breathing within a period of 5 to 40 minutes, where only inhaled surrounding air flows through the heating cartridge. #CMT# : #/CMT# An independent claim is also included for a method for heating breathable air in a training breathing apparatus. #CMT#USE : #/CMT# Heating cartridge for heating breathable air in a training breathing apparatus e.g. filter self-rescuer (FSR) breathing apparatus and oxygen self-rescuer breathing apparatus (all claimed), which is utilized in mining industry and fire brigade. #CMT#ADVANTAGE : #/CMT# The heat-generating material is provided in the interior of the air treatment chamber, where the heat-generating material is granular potassium superoxide, thus eliminating the need for adding hydrophilic or other reactive substances to the material, such that a small amount of contamination less than 1 weight percent does not react with the material. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of a heating cartridge. 1 : Housing 2 : Heat-generating material 5 : Fleece 6-8 : Air treatment chambers 9 : Heating cartridge.</p> |
