  • Patent number: 11859812
    Abstract: Various aspects provide for a multistage fluidized bed reactor, particularly comprising a volatilization stage and a combustion stage. The gas phases above the bed solids in the respective stages are separated by a wall. An opening (e.g., in the wall) provides for transport of the bed solids from the volatilization stage to the combustion stage. Active control of the gas pressure in the two stages may be used to control residence time. Various aspects provide for a fuel stream processing system having a pretreatment reactor, a combustion reactor, and optionally a condensation reactor. The condensation reactor receives a volatiles stream volatilized by the volatilization reactor. The combustion reactor receives a char stream resulting from the removal of the volatiles by the volatilization reactor.

  • Patent number: 11859816
    Abstract: Various kinds of oscillatory instabilities are seen in practical systems. We devise of way of combating these oscillatory instabilities in a thermoacoustic system. Confined combustion environments are prone to large amplitude pressure oscillations known as thermoacoustic instabilities. Although several techniques have been employed to control or mitigate such instabilities, optimization of these methods is achieved at the cost of performing multiple trial and error experiments/simulations. This invention develops a methodology to quantify the spatio-temporal dynamics using synchronization, recurrence, and fractal measures and find the coherent region in such turbulent flow field. Such an analysis provides us with a novel way to detect critical regions responsible for thermoacoustic instability, and other oscillatory instabilities in general, in the flow field and implement an optimized control strategy at these regions.

  • Patent number: 11859838
    Abstract: HVAC load can be shifted to change indoor temperature. A time series change in HVAC load data is used as input modified scenario values that represent an HVAC load shape. The HVAC load shape is selected to meet desired energy savings goals, such as reducing or flattening peak energy consumption load to reduce demand charges, moving HVAC consumption to take advantage of lower utility rates, or moving HVAC consumption to match PV production. Time series change in indoor temperature data can be calculated using only inputs of time series change in the time series HVAC load data combined with thermal mass, thermal conductivity, and HVAC efficiency. The approach is applicable for both winter and summer and can be applied when the building has an on-site renewable power system.

  • Patent number: 11859847
    Abstract: Systems and methods for training a reinforcement learning (RL) model for HVAC control are disclosed herein. Simulated experience data for the HVAC system is generated or received. The simulated experience data is used to initially train the RL model for HVAC control. The HVAC system operates within a building using the RL model and generates real experience data. A determination may be made to retrain the RL model. The real experience data is used to retrain the RL model. In some embodiments, both the simulated and real experience data are used to retrain the RL model. Experience data may be sampled according to various sampling functions. The RL model may be retrained multiple times over time. The RL model may be retrained less frequently over time as more real experience data is used to train the RL model.
