FIELD: heating.
SUBSTANCE: invention is designed for utilisation of exhaust gas heat and may be used for heating enterprises. Boiler plant contains steam boiler, feed-water economiser, heat recovery unit, chemical water cleaning system, heat exchanger of chemically treated water, thermal dearator, heat exchanger, assembly hot well, water seal, pressure reducing plant, vent steam pipeline for thermal dearator, exhauster, main gas conduit, separation unit, condensate collector, by-pass gas conduit and gas-spreading heating with irradiating panels. Panels are linked with main gas conduit after feed-water economiser through outlet from main gas conduit and with heat recovery unit through retain gas conduit.
EFFECT: effective cooling of combustion gases, heating costs reduction and decrease of temperature drops in heated rooms.
