Applications: Gasification.
Your need: To enhance efficiency for electric power generation. MTI can help solve the following gasification challenges:
- Slag flow management
- Clinker formation
- Refractory corrosion
- Vaporization of inorganic species
- Ash deposition on refractory and metal surfaces
- Syngas cooler fouling
- Hot-gas clean-up: filter plugging and blinding
Our solution: By characterizing the fuel with our advanced techniques, we can provide ash behavior predictions for various regions in the gasifier. MTI uses computer-controlled scanning electron microscopy to determine the size and composition of mineral materials within the fuel. Fuel performance may be estimated in terms of slag flow behavior, ash deposition on gas cooling equipment, agglomerate and clinker formation, and plugging of gas-filter systems.
