Boiler Economiser and Waste Heat Recovery Concept Boilers are generally designed to produce steam from water. Water is converted to steam by transferring both sensible and latent heat. Sensible heat is the amount of heat required to increase the temperature of water at constant pressure without changing its liquid state, while Latent heat is the...

Boiler economizers work by transferring heat from the flue gases to the boiler feedwater. The flue gases are typically hot, around 300-500 degrees Fahrenheit, and the boiler feedwater is typically cold, around 100-150 degrees Fahrenheit. The heat from the flue gases is transferred to the boiler feedwater, which raises the water’s temperature. The...

A boiler economizer is a heat exchanger that is installed on the stack of a boiler. It is designed to recover heat that would otherwise be wasted. The economizer transfers heat from the flue gases to the boiler feedwater, which helps to preheat the water before it enters the boiler. This reduces the amount of […]

Boiler economizer is a heat exchanger installed on the flue gas stack of a boiler. Its primary function is to capture and utilize heat from the flue gases that would otherwise be wasted. This process enhances the overall energy efficiency of the boiler system. The economizer operates by transferring heat from the hot flue gases […]

A boiler economizer is a heat exchanger that recovers waste heat from flue gases to preheat boiler feedwater, thus improving overall boiler efficiency and reducing fuel consumption. It acts as a cost-effective solution for saving energy and money by utilizing the otherwise wasted heat from the boiler’s exhaust. How it works: Hot flue gases...
