FIELD: heat exchange.
SUBSTANCE: invention relates to an accumulation hot-water boiler containing a vortex guiding part. The boiler is comprised of a body with a separating part therein, equipped with a separate fire chamber located above the separating part, and a burner supplying flame to the fire chamber. The boiler is comprised of multiple fire tubes with a first side connected with the lower surface of the fire chamber and a second side extending downward into the separating part. The boiler comprises a vortex guiding part with a spiral part located in a spiral along the vertical direction of the body in the separating part. The spiral part is located in a spiral around a central passage located in the vertical direction in the centre of the separating part for directing water, and the central passage constitutes a space made integral with the separating part. The boiler also comprises a discharge part located in a position under the body and connected with the fire tubes.
EFFECT: technical result is an improvement in the efficiency of heat exchange of fire tubes and a provided effect of preventing the accumulation of scale on the part of the lower surface of a fire chamber.
