1.4.4.1 Design of superheated steam generator.
Through a heat-insulated water tank (no. 3 in Fig. 3, 4), a box-section channel is laid (no. 4, Fig. 3, 4),
in which tubular heating elements (no. 6, Fig. 3, 4) are installed. Water is heated up to its boiling
due to heat transfer through channel walls, from tubular heating elements to water. In the channel
steam ducts are installed (no. 5, Fig. 3, 4), through which steam is transferred to a lower channel
part, where it is mixed with air, which incomes from the bottom. Due to convective streams, the air-
steam mixture flows upwards, is heated to 300-330 °С and released to the room through a nozzle
(no. 7, Fig. 3, 4). The tank is filled and re-filled with water automatically, through a valve on a back
of the enclosure. (no. 2, Fig. 3, 4).
1.4.4.2 Design of stone heating unit.
The stone heating unit is a heat-insulated steel tank (no. 9, Fig. 3, 4), in which tubular heating elements
(no. 10, Fig. 3, 4) are installed. A steam-generating stone is laid into the tank. At the top, a heat
insulated door(s) is available (no. 8, Fig 3, 4), which allows either using of some heat for room heating
(the door(s) is/are open) or using all the heat for heating of the stone mass (the door(s) is/are closed).
The tubular heating elements are installed on a foundation (no. 11, Fig. 3, 4), which is equipped with
bimetal thermostats (no. 12, Fig. 3, 4), which cut the power of tubular heating elements after reaching
of a certain temperature inside the tank.
1.4.5 CP design.
The CP consists of two functional units: control panel and power unit. The CP appearance is shown
in Fig. 5.
