An Economizer recovers heat from flue gases and uses it to increase boiler feedwater temperatures, prior to entering the boiler. Cleaver-Brooks offers two types of Standard Economizers - CCE (Cylindrical) and CRE (Rectangular) units.
If your boiler is not equipped with an economizer then you’re losing energy through your stack. Superior Boiler’s economizer was developed to recover this wasted energy while being easy to install and maintain. Your payback depends on your fuel costs, average loading, and hours of operation.
Jul 30, 2019 · The Economizer in Boiler works on the principle of Heat Transfer. Heat transfer usually takes place from high temperature to low temperature. In the case of Boilers, flue gases or exhaust from the boiler outlet are at high temperature and water that needs to be preheated is at low temperature.
Economizer used with Shell and tube waste heat boilers uses the gases from diesel generator exhaust, furnaces, gas turbines, and incinerators. Economizers can use the exhaust gases from an industrial boiler to preheat the cold water (feed water) that is used to fill the boiler. Boiler efficiency is directly related to the temperature of the feedwater.

Economizer. Economizer is used downstream of Boiler bank to preheat the feed water absorbing heat from hot exhaust gases. Economizers are always water tube type. Bare tubes in Economisers are widely used in Industrial boilers and in some applications like Heat recovery boilers in Sulfuric acid plants, Gilled tubes are employed.
The H type fin tube economizer is used to weld the fins in the bare pipe of the province of the coal and the fins are used to replace the bare tube heating surfaces (see below). It is arranged by the heating surface is the same diameter and length of the light tube 6~9 times.
An economizer is a unit that captures heat from the stack, and then returns it to a water system. To determine if a boiler economizer is right for your facility, look at your annual boiler fuel bill and subtract 5 to 10% of the cost. If this is a significant number to you, then you should consider adding an economizer.
2012-10-5 · Boiler economizers are a series of horizontal tubular elements and can be characterized as bare tube and extended surface types.
