FIELD: power engineering.
SUBSTANCE: invention relates to the field of power engineering. Boiler device (10) comprises bearing structure (42) and furnace (12), supported on load-carrying structure in furnace vertical section, wherein furnace is surrounded by walls of water pipes, comprising two side walls (18) and two end walls (20), ceiling (16) and bottom (14), wherein the side walls have a common height H from the bottom to the ceiling, and each of the two side walls comprises a vertical upper portion (30) which extends from the ceiling to level of 30–70 % of the height H, lower section (32), which extends from bottom to level of 30–70 % of height H and has vertical top section (36) of lower section (32) of side wall (18), and intermediate portion (38) bent in the downward out direction, at a level between the vertical upper portion (30) of side wall (18) and the vertical upper portion (36) of lower portion (32) of side wall (18), wherein bearing structure (42) comprises horizontal beams (48), supporting walls, at level below ceiling (16) of furnace. Horizontal beams (48) supporting walls are located parallel to two side walls (18) and directly above vertical top sections (36) of lower section (32) of two side walls (18), and furnace (12) is supported on bearing structure (42) by means of intermediate sections (38) of two side walls connected to horizontal beams (48) supporting walls, so as to balance vertical loads of furnace.
EFFECT: invention makes it possible to create bearing structure for furnace, supported in the middle taking into account effects of horizontal thermal expansion.
