Preheaters Used in the Chemical Industry

Product preheaters are often used to capture heat from one part of the process to add heat to a product stream prior to evaporation or reboiling stage, in order to save on energy.  Preheating also reduces the effects of thermal shock from sudden temperature changes that can be damaging to your process equipment.

Air preheaters are mainly used in fossil fuel power plants for boiler efficiency. Combustion air is heated up by the thermal energy of flue gas, enhancing the combustion process. The preheater recovers the heat from the boiler flue gas, helping to increase thermal efficiency by reducing the heat lost in the flue gas.

This also helps the plant have control over the temperature of gasses leaving their flue stack, helping them to meet emissions regulations.
