Development of Nanocoatings for Primary Heat Exchanger within Condensing Boiler to Allow Replacement of Aluminium Silicon Alloy with Aluminium to Reduce Carbon Emissions, Cost, and Fuel Usage

这项研究旨在开发一种纳米涂层，以防止腐蚀并提高凝汽式锅炉主换热器的导热系数。锅炉制造商断言，铝制换热器因其制造成本低和高导热性能而成为首选材料。不幸的是，在未经处理的铝制热交换器上燃烧家用燃气造成的腐蚀意味着锅炉制造商使用了其他替代热交换器。因此，许多锅炉会对热交换面进行预热(这会浪费燃料)，以避免在打开热水龙头时出现不可接受的滞后。使用具有纳米涂层的铝交换器将减少碳排放，并降低制造商的生产成本和最终消费者的长期成本。

This study is to develop a nanocoating that will prevent corrosion and increase thermal conductivity in the primary heat exchanger of a condensing boiler.Boiler manufacturers assert that aluminium heat exchangers are the preferred material to be used because of its low manufacturing costs and high thermal conductivity properties. Unfortunately, the corrosion which results from burning domestic gas on untreated aluminium heat exchangers means other alternative heat exchangers are used by boiler manufacturers.As a result, many boilers ‘pre-heat’ the heat exchange surfaces (which wastes fuel) to avoid an unacceptable lag when the hot tap is turned on. The use of an aluminium exchanger with nanocoatings would reduce carbon emissions, and reduce production costs for manufacturers, and long term cost to end consumers.
