In a cyclic char fuel oxidation reactor plant comprising: a separate compressor; drive means for driving the compressor; at least one separate expanded means; a source of reactant gas containing appreciable oxygen gas; the compressor comprising an inlet to the lowest pressure stage thereof; a fixed open gas flow connection; the expander comprising an outlet from the lowest pressure stage thereof; means for absorbing any work output of the expander; a number of primary reactor pressure vessel containers equal to the sum of the number of compressor stages plus the number of expander stages and each container comprising: a primary char fuel reaction chamber; an inlet to the primary reactor pressure vessel container; one separate first outlet; the primary char fuel reaction chamber comprising: a refuel end and an ash collection end; a refuel mechanism means for placing char fuel into the primary reactor via the refuel end thereof; a direction of char fuel motion within the primary reactor from the refuel end toward the ash collection end; a peripheral dimension around the outer surface of the primary reactor at right angles to the char fuel motion direction; a volatile matter distillation and char fuel preheat zone; an ash collection zone; a rapid reaction zone; one means for removing ashes; means for preheating the char fuel to that temperature at which the char fuel reacts rapidly with oxygen; means for driving the compressor; several separate changeable gas flow connections; control means; an improvement is described comprising: dividing the peripheral dimension of the primary reactor into a separate inlet portion, a separate outlet portion and separate scaled portion; adding to each the primary reactor: a reactant gas manifold; a producer gas reservoir; wherein all of the reactant gas inlet ports and also all of the outlet ports are smaller in at least one area cross section dimension than the char fuel particles being refueled into the primary reaction chamber.
