Development of coating materials to improve efficiency for high temperature furnace

Steam cracking of hydrocarbons to olefins is a highly endothermic process carried out in large gas-fired furnaces. An increase in the thermal efficiency of a furnace can be translated into an increase of yields, an increase of throughput or a decrease in fuel gas consumption. Applying high emissivity coatings in furnaces is believed to reduce the heat transfer from furnace to environment and increase thermal radiation to the load. However, our current coating formulation has high emissivity efficiency at temperature range of 800-1200 ⁰C. The emissivity value at higher temperature dramatically decreases. This project would aims to developcoating formulation that has high emissivity value at temperature in the range of 1200-1600 ⁰C.
