Fouling resistance of steel
WebFeb 2, 2011 · The fouling of heat exchangers may be defined as the accumulation of unwanted deposits on heat transfer surfaces. The foulant layer imposes an additional resistance to heat transfer and the narrowing of the flow area, due to the presence of deposit, results in an increased velocity for a given volumetric flow rate. WebFouling is the accumulation of unwanted material on solid surfaces. The fouling materials can consist of either living organisms or a non-living substance (inorganic or organic).Fouling is usually distinguished from other surface-growth phenomena in that it occurs on a surface of a component, system, or plant performing a defined and useful …
