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. One-shot heat source can be equipped with ignition device from the row: wind matches, ignition fluid on the basis of paraffin, and dry fuel. Number of saw cuts can be 6 to 12. Distance between saw cuts can be 0.5-1.5 cm. Surface area of each of end faces can not be less than 250 cm2. For arrangement in the place of burnt out fragments of solid body the one-shot source can be equipped with additional fuel cells of the row: dry branches, chips, thinnings, coal. Solid body of one-shot heat source can be made in the form of log piece or beam piece mainly of rectangular section. ^ EFFECT: invention allows increasing ignition and combustion efficiency and usability, as well as enlarging application area of heat source owing to enlarging raw material base. ^ 7 cl, 6 dwg |
