a first portion including a combustion chamber connected to a combustor head, the combustor head including an inlet configured
to direct a flow of filtered exhaust gas to the combustion chamber, the flow of filtered exhaust gas having at least a portion
of particulates removed therefrom; and
a second portion including a housing, the housing including an exhaust gas inlet configured to direct a flow of exhaust gas
to a combustion zone within the housing, the first portion being removably connectable to the second portion;
wherein the inlet in the combustor head is configured to inject a first amount of oxygen for initiating combustion of a combustible
substance in the combustion chamber, and the first amount of oxygen is a volume of oxygen sufficient to enable only partial
combustion of the combustible substance in the combustion chamber.
