A boiler comprises sections arranged of two-phase gravitational thermo-siphons boiling zones of which are placed in gas duct for utilization of heat of outflow gases, and condensation zones – in vertical tubes connecting the distribution and collection collectors that together with down and steam takeoff pipes, and the steam-water and water cylinders, form a steam-generating circuit of natural circulation. Length of distribution and collection collectors is increased with formation of a furnace that is equipped with furnace unit, and the outer surface of vertical tubes forms additional heating surface gas duct of which is connected to the furnace. |
