BIOFACT Fuel Dashboards 6.0 – newly developed graphical results

BIOFACT Fuel Dashboards 6.0 incorporates newly developed equilibrium phase diagrams, obtained with the last release of updated databases of the thermochemical equilibrium software.

Those in house developed graphical representation of equilibrium results (firstly presented in a PhD Thesis) allow to rapidly understand where the 100% liquid and 100% solid phase regions are located in ternary mixtures of major fuel ash oxides.

The most applicable diagram is included in the sample-specific Fuel Dashboard!

0 Ash conveyor
1 Water-cooled DynaGrate®
2 Separately cooled wear zone in furnace
3 Combustion chamber with Inconel® cladded walls
4 Ignition control with air
5 Advanced flame front control
6 VoluMix™ zone in 1st pass
7 Inconel cladded 1st and 2nd boiler pass
8 On-line boiler washing system
9 Integrated baffle walls in 3rd pass
10 Evaporator section
11 Superheater sections
12 Economizer sections
28 CUTNOX® in combination with SNCR

When modeling and predicting the ash behavior in the boiler, it is important to consider local conditions: a cooled wear zone in furnace, the air settings, the washing system and the integrated baffle walls will have an effect into the thermal balance and therefore fuel transformations.

Boiler Operational Efficiency Best Practices from US DOE

Full technical report

In the report “Wise Rules for Industrial Energy Efficiency”, the EPA develops a comprehensive list of baic rules relating to boiler efficiency improvements.

• Boiler Rule 1. Effective boiler load management techniques, such as operating on high fire settings or installing smaller boilers, can save over 7% of a typical facility’s total energy use with an average simple payback of less than 2 years.

• Boiler Rule 2. Load management measures, including optimal matching of boiler size and boiler load, can save as much as 50% of a boiler’s fuel use.

• Boiler Rule 3. An upgraded boiler maintenance program including optimizing air-to-fuel ratio, burner maintenance, and tube cleaning, can save about 2% of a facility’s total energy use with an average simply payback of 5 months.

• Boiler Rule 4. A comprehensive tune-up with precision testing equipment to detect and correct excess air losses, smoking, unburned fuel losses, sooting, and high stack temperatures can result in boiler fuel savings of 2% to 20%.

• Boiler Rule 5. A 3% decrease in flue gas O2 typically produces boiler fuel savings of 2%.

• Boiler Rule 6. Every 40°F reduction in net stack temperature (outlet temperature minus inlet combustion air temperature is estimated to save 1% to 2% of a boiler’s fuel use.

• Boiler Rule 7. Removing a 1/32 inch deposit on boiler heat transfer surfaces can decrease a boiler’s fuel use by 2%; removal of a 1/8 inch deposit can decrease boiler fuel use by over 8%.

• Boiler Rule 8. For every 11°F that the entering feedwater temperature is increased, the boiler’s fuel use is reduced by 1%.
