What is the purpose of a pre-heater?

The purpose of a pre-heater is to recover heat from exhaust gases, which enhances the overall efficiency of a heating system. By utilizing the heat that would otherwise be wasted, it warms the water or fluid entering the boiler. This process reduces the energy required to reach the desired temperature, thus increasing the efficiency of fuel usage and lowering operational costs.

When the pre-heater captures excess heat from the exhaust, it helps maintain optimal temperatures and contributes to more effective combustion within the boiler. This not only promotes better performance but also minimizes emissions by improving the combustion process. Understanding the role of a pre-heater in recovering heat is crucial for optimizing energy usage in stationary engineering applications.
