How to Calculate Boiler Economizer Efficiency

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.

how to calculate boiler economizer efficiency

Base model - Values represent a 1,000,000 Btu/hour gas-fired, hot-water boiler operated for 1,500 full-load hours per year with a thermal efficiency of 80%. The performance of this standard unit is based on ASHRAE 90.1-2007. Thermal efficiency (E t) - Represents a boiler's energy output divided by energy input as defined by ANSI Z21.13. A boiler's thermal efficiency rating should be used to determine …

Increasing Boiler Efficiency with Economizer/Preheater

Apr 26, 2017 · To optimize efficiency, boiler systems today come with a proven combination: economizers and air preheaters. These two systems, when working together, can improve boiler efficiency by approximately 20 percent. It's important that they work together, because an economizer by itself will only provide efficiency increases in the single-digit range.
