to document and assist with the implementation of at least one initiative that will provide greater than 100% pay-back of the evaluation cost, or the evaluation fee will be waived.

COMBUSTION STUDIES:

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 boiler installations.

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 Method.
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 fuel consumption.

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.
