A stove grate for guiding fuel in two flows is described. The grate includes a stationary floor extending between opposed ends of the grate; spaced sidewalls extending along the sides of the floor between the ends of the grate. The floor includes an entrance section at one end of the gate, a fire support section at the other end of the grate above the entrance section and rise section means extending upwardly between the entrance section and the fire support section for guiding a lower fuel flow upwardly along the floor to the fire support section. It also guides an upper fuel flow located above the first flow up to fill a fuel reservoir located above the floor at the entrance section and at the lower part of the rise section means without overflowing the sidewalls. A plurality of combustion air openings in the floor of the grate extend along the upper part of the rise section means and along the fire support section, the entrance section and the lower part of the rise section being free of combustion air openings.
