Due to work performed with Enbridge Consumers
Gas, Vestar and Canmet Energy Technology Centre, Utilities Optimized
personnel have been trained in the process of combustion testing and
monitoring. Utilities Optimized follows a standard procedure developed
by numerous organizations to assess the true efficiency of a steam generation
system. To ensure tight quality control, Utilities Optimized rents it
analyzers from a certified company that provides certification to the
testing reliability of the equipment and results.
The Combustion Study performed by Utilities Optimized
is designed around the ASME Loss Method of determining combustion efficiency.
Individual boilers are fired at fixed rates for fixed period of time.
At the end of the firing period, a printout of that rates efficiency
is produced. Gas, steam and/or water flow to the individual boiler is
then correlated to determine the complete units' mass profile.
The net result of the Combustion Study is the development
of a Fuel to Steam Efficiency chart. This chart, defining the combustion
efficiency at each firing level and fuel to steam efficiency can then
be used to effectively set-up and control the firing or staging of multiple
There are three (3) primary objectives that we strive
to achieve through this process. These objectives are identified as:
1. Determine boiler firing efficiency based on ASME Loss
2. Correlate fuel consumption to process flow, thus developing a Fuel
to Steam Efficiency profile
3. Identify best methods for firing and staging boilers to minimize
In this study, Utilities Optimized personnel need
to work closely with operations personnel to control and maintain complete
boiler plant control. In this process, a more thorough understanding
of system intricacies is developed and understood, allowing for better
evaluation of potential staging effects.
