H Finned Tubes

H finned tubes and H double finned tubes are also manufactured as per customers’ requirements. These are particularly suitable for dust laden exhaust gases, e.g. for H fin economizers in coal and oil fired units or waste incinerators.

A straight exhaust gas passage with adequate spacing between the fins decreases soot build-up on the heating surfaces and contributes to easier cleaning and maintenance operations. The two-piece fin segments are welded on automatically according to the resistance welding method.

The connected load of the machine is 800 kVA. By means of the concentrated introduction of heat (power concentration) at each circular projection the required welding spot is produced resulting in a strong fin-to-tube bond. The number of circular projections is adjusted to the tube diameter.
