Various types of catalysts are used in boilers, depending on the specific application and fuel type. Commonly used catalysts include: - Platinum and Palladium Catalysts: These are effective in promoting the complete combustion of hydrocarbons and are widely used in natural gas boilers. - Cerium Oxide Catalysts: Known for their oxygen storage capacity, these catalysts help in the efficient combustion of both gaseous and liquid fuels. - Iron and Cobalt Catalysts: These are often used in biomass boilers to enhance the breakdown of complex organic materials.
