ONE-SHOT HEAT SOURCE Russian patent published in 2010 - IPC C10L11/00 F23B20/00 

FIELD: heating.

SUBSTANCE: one-shot heat source is made in the form of solid body from wood, at least two edges of which are parallel to each other and form its end parts; at that, solid body on one of the edges has longitudinal saw cuts the depth of which represents larger part of its height; it is proposed to make saw cuts in two groups ; at that, in each group the saw cuts are located in parallel planes, and saw cuts of one group are located at an angle of 70-90° to saw cuts of the other group.
