Combustion process and apparatus which includes a monolith bed through which a mixture of fuel and oxidizer reactants is directed. The initial segment of the bed is formed with cells of an optimum size for causing the reactants to undergo heterogeneous combustion without blowout. One or more downstream segments of the bed are formed with cells of a size smaller than the upstream cells to achieve substantially complete combustion in a bed of relatively compact dimensions. High mass flow rates are obtained under stable combustion conditions with high combustion efficiency and low emissions.

A process for combusting fuel and oxidizer reactants comprising the steps of directing a mixture of of the reactants in a stream through a bed having a plurality of cells which form first passages having wall surfaces for combusting reactants in the stream, causing reactants in the stream to undergo heterogeneous combustion at the wall surfaces, said first cells having a given mean diameter of a size sufficiently large to cause the reactants to undergo self-sustaining combustion, thereafter directing the stream through at least one other monolith bed having a plurality of cells which form second passages having wall surfaces for combusting reactions in the stream, causing the reactants to undergo heterogeneous combustion at the wall surfaces of the second cells, said second and subsequent cells having a mean diameter which is less than the given diameter of the first or preceding cells but sufficiently large to cause the reactants to undergo self-sustained combustion and which is ultimately optimum for the heterogeneous combustion of from 60 to 95% of the reactants in the stream.
