Why boiler use Finned Tubes? - Sunny Steel

Why boiler use Finned Tubes? Finned tubes are used in applications involving the transfer of heat from a hot fluid to a colder fluid through a tube wall. The rate at which such heat transfer can occur depends on three factors: the heat transfer coefficient between each of the fluids and the tube wall; and the surface area to which each fluid is
