Performance Monitoring and Combustion Optimization
Boiler Tuning and Combustion Optimization Microfusion has extensive experiences in boiler combustion tuning and steam header optimization in the Process and Utility Industries. Some typical boiler tuning projects are described below. Boiler MACT, and Steam Header Optimization–
Boiler Optimization and Tuning. EES airflow testing identifies maldistributions in each burner as well as burner to burner imbalances and when performed in conjunction with fuel flow balancing, ensures that the fuel air distributions are optimal and that excess O 2 is minimized. Operation with reduced excess O 2 provides lower NOx emissions and improved efficiency.
For boiler optimisation it is important to address both the combustion system, and the steam and feed-water systems. Combustion efficiency Combustion efficiency indicates the flue gas loss. Boiler efficiency also includes the blowdown and stand-by losses. Whether comparing new or existing boilers, their most efficient operating point is usually
Tuning the boiler reduces the excess air to 9.5% with a flue gas minus combustion air temperature of 300°F. The boiler combustion efficiency increases to 83.1% (E2).
Combustion optimization of a pulverized coal-fired boiler is a complex process requiring in-depth knowledge of combustion, operation of boiler firing system and other factors affecting emissions and unit performance. For best results, combustion tuning needs to be performed before combustion optimization tests are conducted.
• A primary goal of a boiler tune-up is to improve boiler efficiency with respect to combustion operations. What are the tune-up requirements under the Boiler Area Source Rule? • See §63.11223(b) for the actual requirements. • See the Tune-up Guidance and Example Recording Form – Area Sources posted at .epa.gov/stationary-sources-air-
