Mobile forced flow steam boiler - has walls of fire chamber and parallel second flue channel above, formed from finned flow tubes welded together

摘要

The mobile saturated steam boiler with forced flow and two flue channels has a firing chamber with a second channel arranged above it containing evaporator tubes. The walls and the bottom of the fire chamber and the walls of the horizontally extending second channel consist of parallel-flow tubes arranged between annular headers provided with partitions, and the tubes are interconnected by longitudinal parallel fins to form a flue-gas impermeable wall. The headers of the fire chamber and the second channel may have a polygonal shape so that this chamber and channel have a polygonal section and flat side walls.
