Abstract:
1. A method for treating a volume of porous contaminated material, comprising: providing a combustible mixture comprising a porous matrix and a distributed combustible contaminant; conveying the combustible mixture to a reaction vessel having an ignition system; activating the ignition system to initiate a smoldering combustion process in the reaction vessel; distributing an oxidizer into the reaction vessel to sustain the smoldering combustion process; removing cleaned material from the reaction vessel that has been remediated by combustion in the smoldering combustion process; monitoring an amount of cleaned material removed from the reaction vessel; replenishing the combustible mixture in the reaction vessel to sustain the smoldering combustion process; and controlling a rate of replenishing the combustible mixture dependent on the monitored amount of removed cleaned material.
