L-shaped panel PTA 11 is made with the possibility of landing it on the power metal plate 13 on the upper side of the furnace body parallel to its longitudinal axis. For this, the L-shaped PTA panel is made with a thickness of 120-250 mm, a height of 17000-2000 mm, and its L-shaped recess for landing on the upper surface of the sauna furnace - with horizontal dimensions of 600-1000 mm and vertical dimensions of 800-1200 mm.

KATE 15 is made in the form of two collapsible panels with ventilation windows 16. KATE panels 15 are made with the possibility of installation perpendicular to each other along the free sides of the furnace and with a gap between their inner walls and the furnace body. To increase the thermal capacity of KATE 15, its heat storage panels are installed at a distance of 8-10 cm from the free sides of the furnace.

Collapsible panels of batteries PTA 11, FTA 10 and KATE 15 are made of heat-accumulating elements in the form of bricks or figured blocks with ceramic facing and assembly locks. The heat-accumulating elements of these panels are made of fireclay material, clay and / or quartz sand by the method of their cold or hot pressing. The assembly locks of the panels are made in the form of pairs of oncoming spikes and recesses on the mating sides of the heat-accumulating elements of the panels (not shown in the figures).

The heat storage stones 14 of the heater 3 are made in the form of oval natural stones and / or fragments thereof.

For contact heating and heating of the sink, a water heat energy accumulator (tank 1) is made with an area of the side surfaces not less than the area of the side surface of the furnace and a water tank with a volume of 15-30 liters. For the convenience of using water from an open reservoir in a rural bath, the tank 1 is removable and equipped with handles for its transfer (not shown in the figures).

To use the block of the proposed heat accumulators, a design has been developed (Fig. 7 - Fig. 10) for a bathhouse furnace with separate steam room, sink and dressing room. The specified furnace contains a single-walled rectangular metal case, in which a furnace 9 with a loading door 5 is placed, with a grate 8 and an ash pan b. A container (heater) 3 is installed above the furnace 9 for heat-accumulating elements (stones) 14. The cavity of the furnace 9 is connected through a duct system to the chimney 2. On the side of the furnace 9 there is a tank 1 for heating the washing water. The furnace 9 with a heater 3 is configured to place a bath in the steam room (steam room), and the tank 1 adjacent to the furnace 9 for heating the washing water in the washing department (washing) of the bath. The furnace contains a seat 12 for a frontal heat accumulator (FTA) 10 for heating the locker room, as well as a seat 13 for a longitudinal heat accumulator (PTA) 11 for simultaneously heating the steam room and washing the bath. As shown above, the seat 12 for the FTA 10 locker room heating is made in the form of a rectangular pipe (loading tunnel) installed between the furnace body 3 and the loading door 5. For this, the loading tunnel is made from 100 to 400 mm long and with transverse dimensions from 300 to 600 mm, from 300 to 500 mm in height and width, respectively. The seat 13 for the PTA 11 washing and locker heating contains a rectangular metal plate mounted on the upper side of the furnace body along its length. It is made with a thickness of 3 to 5 mm, a length of 300 to 700 mm and a width of 80 to 200 mm.

To adjust the humidity in the steam room, the furnace is equipped with a 7 steam generator. The steam generator 7 contains a filling funnel with a calibrated diameter pipe. The free end of the pipe of the generator 7 is displayed in the heater 3 in the lower layers of its heat-accumulating stones 14 (not shown in the figures).

The furnace for a bath with separate steam room, sink and dressing room operates as follows.

The fuel is loaded into the furnace 9 of the furnace, loaded from the dressing room (Fig. 10); through the door 5 of the furnace and the loading tunnel 12. Next, they burn the fuel in the furnace 9. When burning fuel, the metal walls of the furnace 9 heat up. The heat energy of the upper surface of the furnace 9 is transferred to the heat-accumulating elements (stones) located above the furnace in the heater 3, which accumulate heat for the steam room . At the same time, the front part of the furnace 9, in contact with the frontal FTA 10 battery, heats it and transfers part of the accumulated energy to the waiting room. The longitudinal accumulator PTA 11, located on the upper side of the furnace 9 through the landing plate 13, accumulates its heat, heat from the stove 3 and the chimney 2 for the subsequent slow transfer of accumulated heat to the air in the steam room and the washing room by the walls of the accumulator 11. At the same time, the water located in the tank 1, additionally accumulates heat for the washing room. The conventional thermal energy accumulator (KATE) of the furnace 15, located on the sides of the furnace, draws the steam room cold air through the ventilation windows 16 located at the bottom of the battery 15 and drives it in the space between the heated side walls of the furnace and the internal walls of the battery 15. The heated conventional air additionally heats the air in the steam room and transfers part of its heat to the battery 15 and the walls of the batteries 10 and 11 in contact with the air of the steam room. As indicated above, a steam generator 7 is used to adjust the humidity in the steam room. To do this, water is poured into the funnel of the generator 7, which penetrates through the corresponding pipe into the lower layers of stones 14 of the heater 3. Due to the elevated temperature of the lower layers of stones 14 of the heater 3, water quickly evaporates and the steam room air is saturated with finely dispersed water vapor.

Industrial applicability.
