Heat transfer equipment in service does not remain clean. Dirt and scale are deposited on one or both sides of the pipes, providing additional resistance to heat flow and reducing the overall heat transfer coefficient. The resistances to heat transfer when fouling affects both sides of the heat transfer surface are represented in Figure 9.14.

Designing a Boiler Chimney Heat Recovery System Against Fouling

27/4/2017 · Although they provide high heat transfer due to a combination of high heat transfer coefficients from the base wall and the pins, they also entail high pressure losses. The latter disadvantage is generally not a major issue for convectively cooled blades, where there is availability of higher coolant pressure ratios relative to the surrounding hot gas pressure at the blade trailing edge.

21/12/2017 · This system consists of tubes, i.e. the heat pipes, and convection heat transfer chamber which is finally connected to the boiler chamber. Steam is generated when the hot flue gases flow outside the pipe due to convection. These hot gases transfer their heat to the water present in the tubes and come out with a lower temperature [ 24, 25, 26 ].
