A combustion system such as a furnace or boiler includes a perforated reaction holder configured to hold a combustion reaction that produces very low oxides of nitrogen (NOx).

A flameless thermal oxidizer includes a container in which a ceramic matrix is contained, and a diptube having a passageway extending therethrough, the diptube positioned in and in communication with the ceramic matrix and in which a plurality of gaseous streams are present for combustion at the ceramic matrix, the plurality of gaseous streams including a vent stream and an oxygen stream. A related method is also provided.

A flameless thermal oxidizer (FTO) includes at least one baffle constructed and arranged in a reaction chamber of the FTO to coact with a diptube of the FTO to radially expand a resulting “bubble” or reaction envelope from the diptube outward into a porous matrix of the FTO. A related method is also provided.

System and method utilizing thermochemical energy storage for abatement of volatile organic compounds (VOCs) are provided. The system includes a thermochemical energy storage module cyclically operable in a discharging cycle and in a charging cycle. Abatement of VOCs may be performed in either cycle. Disclosed embodiments are expected to provide a zero-added carbon VOC abatement system that in certain situations can operate uninterruptedly 24/7 with the flexibility to facilitate consumption of energy during periods of inexpensive rates for electricity.

A reactor safety device includes a leg and a well. The leg includes an inlet and an outlet. The inlet is in fluid communication with an outlet of a reactor configured to operate at a pressure less than atmospheric pressure at a location of the reactor safety device. The well includes an inlet in fluid communication with the outlet of the leg. There is a first level in the leg and a second level in the well. The outlet of the leg is vertically lower than the second level. A level sensor is configured to monitor the first level and a controller in communication with the level sensor, a fuel inlet into the reactor, and an oxidant inlet into the reactor. The controller is configured to close the fuel inlet and the oxidant inlet when the first level changes by a predetermined amount.
