Steam Boiler

A steam boiler is a power generation device, used for generating steam by applying the heat energy to water. The pressure range of earlier boilers ranges from low pressure to medium pressure (7 kPa to 2000 kPa/ 1psi to 290 psi). The present boilers are more useful because it works with high pressure than old ones.

What is An Economizer? | How does An Economizer Work?

In simple words, an economizer is part of the boiler that uses waste heat to heat the incoming water. The economizers are used for different applications such as engines, power plants, HVAC, and boilers. In short, an economizer works as a heat exchanger. The economizers in the boilers are used to increase the energy efficiency of the system.
