FIELD: power engineering.
SUBSTANCE: boiler comprises furnace with burners, evaporating heating surfaces, horizontal rotatable gas duct with the steam overheating surface for heating the primary steam flow, and gas duct. The gas duct receives steam overheating surface for heating intermediate steam flow. The bottom section of the rotatable gas duct receives shielding surface for heating primary steam flow and distributor of heat fluxes. The distributor of heat fluxes is made of assembled units the number of which depends on the steam parameters and type of the fuel.
EFFECT: enhanced efficiency.
