Boiler Economizer: Boost Your Boiler's Performance I RasMech

Mar 03, 2021 · Summary. Economizers lower the consumption of fuel for a given steam demand. They also reduce thermal stress in the boiler and add heat transfer surface area to the boiler system. "By recovering waste heat, an economizer can often reduce fuel requirements by 5% to 10% and pay for itself in less than 2 years.".

Most mid and large size utility boilers have an economizer section. The economizer is a heat recovery device, usually located in the convection or back pass, which is designed for the transfer of heat from the external flue gases to the incoming colder feedwater. The feed-water enters the boiler through the economizer inlet header.

The Boiler Efficiency Calculator allows you to calculate the energy efficiency benefits of adding one type of economizer to a boiler system. Economizers are heat exchangers that transfer the heat in the flue gas to another medium‚ generally the boiler feed-water‚ although other streams are sometimes used such as make-up water. There are 2 types of economizers: non-condensing and condensing. Non-condensing economizers. The most common are non-condensing economizers.

To optimise economiser design for better performance

economizer is maximum allowable flue gas velocity. Higher velocity provide better heat transfer and reduce capital cost.[4] Economiser tubes are employed in fossil fuel power plants to preheat the boiler feed water before it is introduced into the boiler drum and to recover some of the heat from the flue gas leaving the boiler.

Boiler Economizer - Bright Hub Engineering

May 31, 2010 · Boiler Economizer is usually fitted to increase the efficiency of the boiler by increasing the heat recovery surface so that the maximum amount of heat is recovered from the burnt gases. This is achieved by heating the feed water to the boiler from the burnt gas before it leaves the furnace. In this article we discus the inspection carried out in the economizer and on it gas side of the boiler.
