Where is a closed feedwater heater located in relation to the boiler?

A closed feedwater heater is located between the pump and the boiler. This positioning is crucial for the operation of the feedwater heater, as it allows the water being pumped to the boiler to first pass through the heater, where it is pre-heated before entering the boiler.

The function of the closed feedwater heater is to increase the temperature of the feedwater using waste heat from the condenser or other sources. This pre-heating process improves the overall efficiency of the boiler system because it reduces the amount of energy required to bring the water to the necessary temperature for steam generation. By placing the feedwater heater in this location, the system can efficiently recover and utilize heat that would otherwise be lost, resulting in better energy utilization and reduced fuel consumption for the boiler.

Understanding the placement of components in a boiler system is essential for optimizing its performance and efficiency, making the knowledge of where a closed feedwater heater is positioned particularly valuable for operating engineers.
