Steam generators. In many applications: The amount of steam required is too small to warrant a shell boiler, i.e. Less than 1 000 kg h. The small process requiring steam operates on a day shift only, meaning that the plant would be started every morning and shut down every night.

Economizers, therefore, help in reducing such heat loss and energy input in the steam boiler. Types of Economizers: There are 2 types of Boiler Economizers used in steam boilers.
Get PriceBoiler Economiser: Boiler Economiser ( Sometimes Called Economizer ) is the Energy improving device that helps to reduce the cost of operation by saving the fuel.. The economizer in Boiler tends to make the system more energy efficient.. In boilers, economizers are generally Heat Exchangers which are designed to exchange heat with the fluid, generally water.
Get PriceThe first economizer, patented in 1845, was used to improve the efficiency of boilers used in steam engines for mills and factories. By the 20th century, almost all steam engine boilers included economizers as a standard feature. Here, we will explain how modern economizers reduce energy consumption and improve boiler energy efficiency.
