Embodiment Construction

[0021] In one aspect, the invention relates to a plasma torch assembly that can be used in combination with a reactor vessel, such as a gasification reactor or a vitrification reactor.

[0022] In various embodiments, the plasma torch is configured to deliver a jet or plume of high temperature gas flow (also referred to as a superheated gas flow) into the chamber around which the plasma torch delivers relatively cold gas ( That is, the structure of the shielding gas) (that is, the protection inlet assembly) is used in combination. The guard inlet assembly may deliver a combination of two or more low temperature airflows surrounding the superheated airflow. The guarded inlet assembly can be connected to the tubular or conical chamber (with openings at either end) of the tuyeres that convey all the gas flow to the process of the gasifier or furnace. The chamber can be lined with refractory material and can be cooled by a fluid, potentially with a water jacket or tubular cooling...

Abstract

An apparatus comprising: a tuyere chamber; a plasma torch configured to generate superheated gas and direct the superheated gas into the tuyere chamber in an axial direction; and a shielding gas inlet assembly, the shielding gas The inlet assembly is configured to direct shielding gas into the nozzle chamber, wherein a first portion of the shielding gas is injected coaxially with the superheated gas and a second portion of the shielding gas is injected as a swirl flow shielding the nozzle wall.

Description

technical field [0001] The present invention relates to a plasma feed nozzle for a gasifier, furnace or other reactor vessel. Background technique [0002] A plasma gasification reactor (sometimes referred to as a PGR) is a known pyrolysis reactor that is used to process a variety of materials including, for example, metal waste, hazardous waste, other municipal waste or industrial Waste and landfill waste, as well as plant waste or biomass material, to yield useful materials such as metals or synthetic gas (syngas) or waste where vitrification is undesirable for easier disposal. In this specification, "plasma gasification reactor" and "PGR" are used to refer to basically the same type of reactor applied to gasification or vitrification or both. Unless otherwise indicated, terms such as "gasifier" or "gasification" used herein may be understood to apply to "vitrification furnace" or "vitrification" alternatively or additionally, and vice versa. [0003] For example, the U....
