Coal Testing.
MTI's analysis demonstrates how ash-forming components in coal, biomass, and petroleum coke impact power system performance.
Key improvements our clients have made based on this information include reduction of:
- Abrasion and erosion
- Slag flow problems
- Wall slagging
- Convective pass fouling
- Deposit strength
- Ash resistivity (ESP performance)
- Popcorn ash formation (SCR performance)
Fly ash
Applications

Analytical Methods
MTI uses computer-controlled scanning electron microscopy (CCSEM) to provide quantitative information on the impurities of fuels, and as an accurate means of determining and predicting the effects of ash on power system performance. SEM techniques are also used to identify problematic materials, such as bonding phases in deposits, and the conditions under which they form.
In addition, MTI developed Coal Quality Management System (CQMS) software to calculate advanced indices relating coal characteristics to ash behavior in a coal-fired utility boiler.
Technical Interpretations
Upon completion of analysis, professionals at MTI review the SEM data and other analyses and provide our clients with detailed reports that include summaries of key findings and recommendations for solving specific problems and achieving enhanced power system performance.
