Combustion Optimization
Solving combustion related problems in boilers and optimizing furnace combustion can bring substantial benefits to plant operation in the areas of performance, operability, reliability, availability, capacity. At the same time, emissions are often reduced through more uniform flue gas conditions that help to improve the operation of emission control equipment such as electrostatic precipitators (particulates) and SCR (NOx). Heat rate improvements of 20-50 Btu or more have often been realized after an optimization program has been completed.
Fast Fact
- Combustion experience includes all common fuels:
- Natural gas
- Oil
- Coal
- Wood and refuse fuels
- Knowledge of burner types and systems includes:
- Single and opposed wall
- Tangential (T-Fired)
- Cyclone
- Roof-fired
- Stoker furnace configurations
- Assessing and diagnosing boiler combustion conditions uses proven techniques that include a multi-point grid of economizer duct sample probes for gaseous analysis of the flue gas for oxygen (O2), carbon monoxide (CO) and nitrogen oxides NOx and other flue gas species as required.
- Flyash samples can be obtained for analysis of unburned carbon content (UBC) via isokinetic or high volume sampling from multiple points to provide additional knowledge during the optimization testing.
- Other source tests may be utilized as necessary for additional diagnostic information.
Our optimization program are directed, on-site, by engineers with more than thirty years of plant expereince who are very capable of "thinking on their feet" during plant testing. This ensures that the best test data is obtained and provides flexibility for changes to the test plan and schedule that will improve the test results. They continuously interface with plant operations personnel including the boiler operators themselves. This interaction provides a clear understanding of the implications of the test configurations on plant operability, performance, and emissions to ensure that a practical and truly useful solution can be presented to the client.
