Boiler Efficiency Calculator
Natural Resources Canada has developed an online Boiler Efficiency Calculator to help managers quickly analyze the efficiency of boiler operations associated with heating and steam plants fired by natural gas and fuel oil.
By estimating the efficiencies of steam boilers and high temperature water generators‚ such as those used in central heating and industrial steam generation (with input firing rates of 10 to 200 GJ/h)‚ this online tool will help companies make informed decisions and investments that lead to performance optimization‚ such as:
- upgrading control systems
- installing additional heat exchangers‚ economizers and air heaters
- replacing existing systems with new‚ more efficient equipment.
There are numerous energy losses from a boiler. While most of them are minor‚ and comprise about 1% or less of fuel input‚ there are two or three major losses that typically represent 10 to 20 % of fuel input. The Boiler Efficiency Calculator focuses on these latter losses and the factors that contribute to them.
Disclaimer: The Boiler Efficiency Calculator (BEC) produces results which are based on simplifying assumptions, primarily with respect to fuel composition, and are only intended for general information purposes. The results should not be used to determine efficiency for contractual purposes, such as for boiler acceptance tests. BEC is not intended to serve as a guide to be used in investment or other commercial activities.
