Oil-fired heating boiler - has burner chamber of vertical standard gas bottle, with lower central aperture for burner flame tube

摘要

The heating boiler has a suspended, rotary-symmetrical burner chamber. The upright burner flame projects into through a constricted aperture. The flue gases are fanned-out at the highest hottest point of the chamber, conducted downwards along the vertical wall, concentrated due to the constriction, sucked into the flame root, and re-circulated. Aperture and burner flane tube form a ring gap, and the gases pass through a gap, to an after heater surface, formed by a ring of vertical tubes. The gases are then deflected through 90 deg.
