Claims15
A device for use in a thermal oxidation system for enhancing reaction kinetics for incineration of one or more components of a gaseous waste stream, the thermal oxidation system comprising a combustion chamber having a chamber inlet in fluid communication with a burner configured to combust a fuel and air mixture to form a thermal oxidizer flue gas for the incineration of the one or more components of the waste stream, and a chamber outlet for exhausting the incineration products, the device comprising:
- an elongated body having a first end, a second end, a side wall extending between the first end and the second end, the body having a device inlet configured to receive the waste stream, and a device outlet configured to introduce the waste stream into the combustion chamber, and the body defining a passage between the device inlet and the device outlet;
- wherein the device outlet is spaced from the device inlet to allow the waste stream to be heated while passing through the passage of the device from the inlet towards the outlet;
- wherein the device inlet comprises one or more openings located at or proximate the first end of the elongated body, and the device outlet comprises one or more openings in the side wall of the elongated body, located at or proximate the second end of the elongated body, or at an intermediate point between the first and second ends of the elongated body;
- wherein the device is configured to be positioned within the combustion chamber orthogonal to the direction of flow of the thermal oxidizer flue gas through the combustion chamber from the chamber inlet towards the chamber outlet, to introduce the waste stream and/or direct the waste stream flow in the combustion chamber between an angle of 90° relative to the flow direction of the thermal oxidizer flue gas and an angle opposing the flow direction of the thermal oxidizer flue gas to promote mixing of the waste stream with the thermal oxidizer flue gas.
A thermal oxidation system for incineration of a gaseous waste stream, the system comprising:
- a combustion chamber having a chamber inlet in fluid communication with a burner configured to combust a fuel and air mixture to form a thermal oxidizer flue gas for the incineration of the waste stream, and a chamber outlet for exhausting the incineration products;
- and
- at least one device in fluidic communication with a respective waste-stream line, and positioned within the combustion chamber for enhancing reaction kinetics for incineration of one or more components of the waste stream,
- the at least one device having an elongated body having a first end, a second end, a side wall extending between the first end and the second end, the body having a device inlet configured to receive the waste stream, and a device outlet configured to introduce the waste stream into the combustion chamber, and the body defining a passage between the device inlet and the device outlet;
- wherein the device outlet is spaced from the device inlet to allow the waste stream to be heated while passing through the passage of the device from the inlet towards the outlet;
- wherein the device inlet comprises one or more openings located at or proximate the first end of the elongated body and the device outlet comprises one or more openings in the side wall of the elongated body located at or proximate the second end of the elongated body, or at an intermediate point between the first and second ends of the elongated body;
- and
- wherein the device is positioned within the combustion chamber orthogonal to the direction of flow of the thermal oxidizer flue gas through the combustion chamber from the chamber inlet towards the chamber outlet, to introduce the waste stream and/or direct the waste stream flow in the combustion chamber in a direction that is between an angle of 90° relative to the flow direction of the thermal oxidizer flue gas and an angle opposing the flow direction of the thermal oxidizer flue gas to promote mixing of the waste stream with the thermal oxidizer flue gas.
