GTI and team members CanmetENERGY and Linde worked on developing technologies at the pilot-scale to significantly improve the performance and economics of current oxy-fired pressurized fluidized bed combustor systems and reduce scale up risk. The technologies include: an In-bed Supercritical CO₂ (SCO₂) Heat Exchanger, the objective being to quantify SCO₂ heat transfer coefficients and pressure drop in an Oxygen-fired pressurized fluidized bed combustor (Oxy-PFBC) environment to anchor design rules for scale up; Staged Coal Combustion, the objective being to develop design rules for placement of staged coal combustion injectors to appropriately distribute heat throughout the bed to maintain an oxidizing environment and avoid slagging; and an Isothermal Deoxidation Reactor, the objective being to define operational limits on flue gas O₂ concentration for an isothermal catalyst bed and demonstrate heat recovery from this deoxidation unit. In-bed SCO₂ heat exchanger manifolds were successfully manufactured and installed in the combustor at CanmetENERGY. Staged fuel injectors were designed and fabricated. A task to test an oxygen carrier in the fluidized bed was also planned. A Quasi-Isothermal Deoxidation Reactor (Q-IDR) concept was developed and fabricated, consisting of two adiabatic catalytic reactors with a single inter-stage cooler with SCO₂ as the coolant. The project was stopped prior to testing these technologies due to damage to the hardware on the related Oxy-PFBC Phase II project (DE-FE0009448).
