BATH FURNACE AND HEATING METHOD OF BATH FURNACE Russian patent published in 2020 - IPC F24B1/02 F24B5/02 F24B7/04 

FIELD: heating.

SUBSTANCE: group of inventions relates to heating devices on solid fuel used for heating of steam room with possibility of long-term generation of fine steam in sauna baths. Bath furnace includes housing consisting of two side, front and rear vertical walls and horizontal base with legs, furnace located inside housing, air vent, grate arranged on grate frame, portal with door installed on frontal side of housing, metal bed for stones arranged above furnace, starting pipe, flame arrester. Metal bed for stones has mass making 50 % of weight of whole bath furnace. Height of metal bed for stones extending above walls of bath furnace housing makes 40 % of height of whole bath furnace. Metal bed for stones has ledges in the form of truncated cones on its lower side to increase useful area of contact of furnace gases and acceleration of heating of metal bed for stones and projections in the form of truncated cones on its upper side to increase the area of contact with stones laid on metal bed for stones, acceleration and intensification of their heating and to increase surface for water evaporation and production of steam. Flame arrester is composed of two parts for possibility of its replacement through the door without dismantling the bath furnace itself.

EFFECT: technical result is increase of efficiency, increase of heat output and reliability of bath furnace, simplification of operation and maintenance of bath furnace.
