why economizer and air pre-heaters are provided in boilers

Why Economizer and Air Pre-Heaters are Provided in Boilers

Most of the high capacity boilers firing coal operate with an efficiency of around 86% on the Higher Heat Value basis. Loss of around 14% can be attributed to various losses of which the dry gas loss is about 35% of the total. When both economizers and air pre-heaters are not provided the boiler efficiency drops to around 66% from 86…
