A reactor for oxidization of low-caloric-value organic 
impurities contained in the air has been simulated. It comprises a 
tube with a recuperator, filled with a porous carcass mix, and includes 
a heating element. The influence of the heating-element placement, 
the heat losses through the upper cover of the reactor, the flow rate 
of a gas mixture, and the power of the heater on the maximum temperatures 
of the porous carcass and the gas and on the concentration of the 
incompletely oxidized organic impurity at the output of the reactor 
has been investigated. It is shown that, to burn an impurity completely, 
it will suffice to heat the gas Teto 300 K. It has 
been established that it is best to place a heater at the level of 
the upper cut of the inner tube of the reactor.
