Combustion Tuning of Tangentially Fired Boilers Case Study
HRL improves tangentially fired boiler performance resulting in major cost savings for Australian Generator
As a result of the combustion tuning project, this Australian generator has experienced the following benefits:
- A measurable improvement in boiler thermal efficiency, equating to permanent annual fuel savings;
- A significant reduction of carbon dioxide emissions;
- A reduction in excess oxygen setpoint; and
- Reduction in the flue gas velocity through the economiser.
HRL estimates the savings of the combustion tuning to be between $0.5 million/annum and $1 million/annum, including the reduction in maintenance effort and forced outages attributable to fly ash erosion. HRL is currently working with this client to explore options for further optimisation of the combustion for this boiler and the remaining boilers at the client's site.
