Why Economizer and Air Pre-Heaters are Provided in Boile

Author: Dr V T Sathyanathan 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.

Coal/Biomass Boiler Economiz

Boiler economizer is part of the heating area of boiler, to heat the feed water into saturated water inside the flue ducting, due to its absorption of low temperature flue gas heat, the economizer reduces the exhaust temperature of flue gas, save the energy, improve the efficiency, so called as economizer.

How to Run a Coal Fired Boiler at the Best Efficien

Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50% losses are carbon loss and dry gas loss.

What is the function of economizer in thermal power pla

Modern-day boilers, such as those in coal-fired power stations, are still fitted with economizers which are descendants of Green's original design. In this context they are often referred to as feedwater heaters and heat the condensate from turbines before it is pumped to the boilers.
