A barbecue grill apparatus for sustaining charcoal burning in an outdoor smoker/cooker has a divider wall with a plurality of bends that form a circuitous pathway between opposing surface sections of the wall. The wall is received into a heat chamber of the smoker/cooker resting on its bottom edge, and the pathway is lined with cooking fuel. The fuel is burned along the pathway which causes the fuel to burn slowly and at a reduced heat.
