H Finned Tube Natural Circulation Boilers

H Finned Tube Natural Circulation Boilers

The heat transfer tube of the boiler adopts the H-shaped fin tubes, it is to weld two pieces of steel with arcs in the middle of the arc symmetrically onto the raw tube to form the fins (ribs), the front shape is quite like the letter "H", so it is called H-finned tube. The fins of the H-finned tube are rectangular, approximately square, with a

Free HRSG Design Tutorial - Thermosyphon(Natural) Circulation

Thermosyphon(Natural) Circulation. Conventional, vertical tube boilers are generally designed for natural, "thermosyphon", circulation. This means the water and steam/water circuits are arranged so that the two phase mixture in the steam generating tubes rises to the steam drum by thermal lift of differential density and is replaced by water from the drum by gravity flow.

China Finned Tubes/Kainon H Finned Tubes for Heat

For water tube boilers, heat flux, q = Uo x (tg - ts) x At/Ai,Where Uo = overall outside heat-transfer coefficient, Btu/ft2-hr-°F tg, i s are gas and steam temperatures, °F At, Ai are the tube outside and inside surface areas, ft2/ft. This ratio is for bare tubes, while for finned tubes it could be high, say 5 to 12. Hence, one must be careful
