Gas or oil burning heating boiler - has three fuel gas channels and third channel is on opposite side of partition

摘要

The third fuel gas channel (10) is compact and is on the opposite side of a non heating medium conducting partition (9) inside the combustion chamber, running from the door (6) to the flue pipe (8). It lies inside the second fuel gas channel (2) between a hollow body (3) and the heating medium conducting wall (1). The heat emitting surface of the third fuel gas channel has a number of radial inward projecting ribs, and can be of varied thickness or coated with insulation. USE/ADVANTAGE - Gas- or oil-fired heating boiler operates with reduced risk of condensation.
