Fuel heaters are used in systems for turbine engines to prevent what from clogging system filters?

Debris

Ice crystals

Fuel heaters are used in systems for turbine engines to prevent ice crystals from clogging system filters. When flying at high altitudes, the temperature can drop significantly, leading to the formation of ice crystals in the fuel. These ice crystals can clog the system filters, disrupting the flow of fuel to the engine and potentially causing engine failure. By heating the fuel, the ice crystals are prevented from forming, ensuring smooth operation of the engine's fuel system. Dust particles, rust, and debris are not typically the main concern in this scenario.
