Menetelmä kaasugeneraattorin toiminnan optimoimiseksi ja kaasugeneraattori

A method for optimizing the operation of a gas generator having a housing part, at the upper end of which are elements for supplying fuel to a fuel compartment inside the housing part. The fuel descends by gravity onto a grate, a combustion zone being formed above the grate, with elements for supplying gasification gas thereto. The grate includes two concentrically arranged first and second grate parts, at least one of which grate part can be turned around an axis of rotation passing through a joint centre. The grate parts can be moved in the direction of the axis of rotation towards each other into their mutually interlocking position, and away from each other, into a position partly or completely out of the interlocking position. The grate parts move with respect to each other to regulate the flow of gases through the grate and/or the removal of ash.
