HOT WATER BOILER Russian patent published in 1994 - IPC

FIELD: thermal power engineering. SUBSTANCE: boiler has shell 1 with a furnace, framing and intermediate screens from heat exchange tubes 22 combined by manifolds, branch pipes with heat-transfer agent feed and bleed systems, gas ducts for passing combustion products with partitions for cross flowing over tubes 22. Tubes 23 with nozzles 24 located in the converging zone of the annular channel are eccentrically mounted in heat exchange tubes 22. Axes of tubes 23 with nozzles 24 are located in the sector of heat flow distributing centers with eccentricities proportional to the value of displacement of the sectors. Tubes 23 with nozzles 24 are connected to heat exchange tubes 22 at the inlet by partitions 25 with a hole, have inclined half-washers 26 are plugged and form sections which tube 1 has more than one. EFFECT: improved structure. 4 cl, 4 dwg
