Computer modeling brings slag control into the 21st century
- Fuel Tech Inc., Stamford, CT (United States)
Many power plants have switched from bituminous coals to Powder River Basin coals to comply with lower SOx emissions limits. Although this has been a successful strategy, increased slagging has led many plants to seek coals with lower sodium content. But the increased demand for these coals has raised their prices. Can anything else be done to simultaneously widen fuel options, control costs, and keep the slag devil at bay? Targeted In-Furnace Injection (TIFI), which uses CFD modeling and virtual reality visualization techniques can address all three issues. The modelling program targets areas of the radiant and convection sections of a boiler with chemicals to reduce or eliminate slagging and fouling. The article describes the two different forms of CFD modelling and the virtual reality engine used in TIFI technology. The technology has been successfully used with the same chemical attitude for three years at Hugo Station in Fort Towson, OK. 3 figs.
