Industrial Preheaters for Energy Recovery in Paper Mills

Industrial preheaters for energy recovery in paper mills are a common application.

Preheaters are typically used to heat air or other fluids flowing through a system to increase its temperature, thereby reducing energy consumption in subsequent production processes. In a paper mill, preheaters can be used to preheat air, water or steam to improve the overall energy efficiency of the system.

The following are some of the types of industrial preheaters that may be used for energy recovery in paper mills:

Air Preheater: Air preheaters are used to transfer heat energy from the flue gases exiting the system to the new incoming air. This helps to improve combustion efficiency and reduce fuel consumption. In paper mills, this type of preheater is usually used in conjunction with a boiler system.

Water Preheater: Water preheaters are used to preheat water entering a boiler or other heating system. By utilising waste heat, the amount of heat that needs to be extracted from other energy sources is reduced.

Steam Preheater: Steam preheaters are used to preheat steam before it enters the process. This helps to improve the thermal efficiency of the system.

Waste Heat Recovery Unit: This is a generic term that can include many types of preheaters used to recover energy from a waste heat source. In a paper mill, waste heat can come from combustion processes, drying equipment, or other production processes.
