Safety, monitoring and control features for thermal abatement reactor

A system comprising:

• a first enclosure including a thermal abatement reaction chamber;
• a second enclosure associated with the first enclosure;
• a sensor within the first enclosure and adapted to detect flammable gas within the first enclosure;
• a heater within the first enclosure and adapted to maintain the sensor at a defined temperature;
• a first barrier within the second enclosure, coupled to the sensor, and adapted to limit an amount of energy provided to the sensor to a level below a flammable gas ignition energy level;
• and
• a second barrier within the second enclosure, coupled to the heater, and adapted to limit an amount of energy provided to the heater to a level below the flammable gas ignition energy level.

A system comprising:

• a shared fuel source;
• a fuel circuit coupled to the shared fuel source and adapted to provide a stable flow of fuel, wherein the fuel circuit includes:
• a meter to determine an amount of pressure within the fuel circuit,
• a pump to create pressure within the fuel circuit, and
• a regulator to adjust the fuel pressure to a defined pressure;
• and
• an inlet adaptor coupled to the fuel circuit and adapted to receive fuel and to supply the fuel to a thermal abatement reaction chamber.
