Combustion OptimizationOxyFire Sensors: Typically used in a coal-fired power boiler, the high temperature, in-situ oxygen sensor is generally installed in the boiler water-wall, above the nose arch and above each of the burner banks. This configuration allows the boiler operators to center the fireball in the radiant zone and "balance" the boiler.
Typically installed above the slag line, the sensors give the boiler operators a unique perspective on the combustion process, eliminating the typical "air infiltration" that confuses "low temperature" sensors located in the back pass.
Benefits from using Marathon Monitors' Combustion Optimization System to "trim" the draft are:
- Balanced boiler - Centering the fireball
- Minimizing NOx formation
- Reduces over-all maintenance costs
Providing the operators with this type of information allows them to do their job more efficiently, eliminates CO (carbon monoxide) pockets, and helps in achieving "lowest cost" megawatts.
