An economiser boiler is a type of boiler that mainly uses heat from the flue gas and preheats the feed water. This helps to save energy and reduce emissions. Economiser boilers are mainly used in large industrial and commercial applications.
How Does an Economiser Boiler Work?
An economiser boiler comes with a heat exchanger placed in the flue gas path. As the flue gas passes by the heat exchanger, it can heat the feed water. The preheated feed water then enters the boiler, where it is again heated and converted into steam.
The two main types of economiser boilers are:
Non-Condensing Economiser Boilers: These boilers function at a temperature above the dew point of the flue gas. Thus the flue gas does not condense, and all of the heat gets transferred to the feed water.
Condensing Economiser Boilers: These boilers function at a temperature below the dew point of the flue gas. Thus the flue gas condenses, and the latent heat of condensation is transferred to the feed water.
Benefits of Using an Economiser Boiler
There are many benefits to using an economiser boiler, such as:
Reduced energy consumption: Economiser boilers are designed to save energy by preheating the feed water. This reduces the amount of fuel needed to generate steam.
Reduced emissions: Economiser boilers are designed to reduce emissions as they reduce the amount of fuel burned.
This also helps to improve air quality.
Improved Boiler Efficiency: Economiser can also improve the efficiency of the boiler as it transfers more heat from the flue gas to the feed water.
Reduced Maintenance Costs: Economiser boilers can even reduce maintenance costs by mitigating the amount of soot and other deposits that form on the boiler tubes.
