Ultra-thin superhydrophobic coatings for heat exchange surfaces with simultaneous condensation to increase boiler efficiency: Corrosion protection, drip enhancement enhancement and condensate flow rate (ecoDROPdenser)

The ecoDROPdenser project aims to develop ulta-thin superhydrophobic coatings for the improvement of the thermodynamic yield and the protection against corrosion of surfaces used for phase change heat exchange with condensation. The usage of the condensation latent heat increases the energy performance of the boilers, but introduces additional problems mainly due to the corrosive character of the condensates; these contain H₂SO₄ from the SOx of the flue gases. The envisaged coatings will (i) be ultra-thin and therefore will not decrease the thermal conductivity, (ii) be deposited from the gas phase and therefore will not produce liquid waste streams, (iii) enhance the dropwise condensation over the filmwise condensation and the water collection rate and therefore will offer increased heat thransfer coefficient. The developed coatings will be evaluated thermodynamically in commercial available heat exchangers.
