Low Rank Coal Optimization

Performer: NETL Research & Innovation Center

Project No: FWP-2012.03.03 Task 4

Project Description

NETL's in-house research team is using an integrated approach to combine theory, computational modeling, experiment, and industrial input to develop physics-based methods, models, and tools to support the development and deployment of advanced gasification based devices and systems. The activities in this effort include developing and applying computational and modeling tools to simulate complex flows in applications such as transport or entrained flow gasifiers.

Transport Integrated Gasification (TRIG) is a gasification reactor design supported by the U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL) and the Southern Company. TRIG is a pressurized, partially-dried feed, dry ash (non-slagging) discharge and refractory lined gasification that operates under coal ash deformation temperature. The NETL Research & Innovation Center is developing a set of computer models for co-feeding of low rank coals and other feedstocks including biomass for the TRIG reactor. Validation of these models will enable reliance on them for design and optimization purposes.

This work will develop a hierarchy of models for numerical simulations of TRIG co-feed conditions that span from fast running reduced order models (ROMs) to high fidelity multiphase computational fluid dynamics (CFD) models. Each model will have uncertainty quantification associated with its predictions to allow a user to choose a model based on the trade-offs between computational speed and uncertainty in the predictions.
