Performance Analysis of Economizer Using Different

A feedwater economizer reduces steam boiler fuel requirements by transferring heat from the flue gas to incoming feedwater. Boiler flue gases are often rejected to the stack at temperatures more than 100°F to 150°F higher than the temperature of the generated steam. and do the calculation. In another case, inside layer in the

The Economizer: What, Why, and How? - Boiler Blog

Apr 14, 2017 · The process is simple. As the flue gas exits the boiler, it enters an economizer with finned tubes. The finned tubes absorb the heat and raises the temperature of the boiler feed water, lowering the needed energy input. Why Add an Economizer? Adding an economizer will increase boiler …

Increasing Boiler Efficiency with Economizer/Preheater

Apr 26, 2017 · The more efficient your boiler system is, the better your bottom-line results will be. Even one point of efficiency increase can make a big difference, especially in a system that is, by nature, inefficient compared to other fuel sources. To optimize efficiency, boiler systems today come with a proven combination: economizers and air preheaters

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.

Boiler Flue Gas Economizer Calculations - Boiler and

Jun 15, 2007 · A= total surface area of the heat exchanger. A simple starting point is to assume a gas velocity thru the bank of 50-60 fps, and the UA = 1.5 *WgCp,g ( this is equivalent to an NTU = UA/WCp = 1.5 ). The number of tubes operating in parallel to yield a tubeside water velocity of 10-15 fps. A more accurate method is the e-NTU method, but I think

Economizers designed for natural gas only, would likely plug-up if installed on a coal boiler and would face increased risk of corrosion if installed on an oil-fired boiler. Some units are designed to keep the flue gases above condensation temperature, and others are made of materials that resist the corrosive effect of condensed flue gases.

How to Calculate Boiler Economizer Efficiency

A generally accepted "rule of thumb" is that about 5% of boiler input capacity can be recovered with a properly sized economizer. A higher percentage can be recovered with a Flue Gas Condenser, assuming there is enough cold water to condense all of the flue gas that is available. The calculations to determine the efficiency of condensing economizers are complex.

Boiler Economizer - Michaels Energy

A basic heat recovery system, or "boiler economizer", consists of an air-to-water heat exchanger placed in the stack of the boiler exhaust. Heat is transferred from the exhaust gas to boiler feed water or other heating load. Economizers are selected based on a number of parameters. Exhaust gas condensation is an issue and this and other
