Abstract
An apparatus includes a tuyere, a plasma torch positioned to inject hot gas into the tuyere, and a plurality of nozzles configured to inject a combustible material into the tuyere for combustion of the combustible material within the tuyere. The apparatus can be used to practice a method including: injecting a combustible material into a plurality of tuyeres in a wall of a reactor vessel, using a plasma torch to inject hot gas into the tuyeres to ignite the combustible material, and directing heat from combustion of the combustible material into the reactor vessel to preheat the reactor vessel.
Claims9
An apparatus comprising:
- injecting a combustible material into a plurality of tuyeres in a wall of a reactor vessel;
- using a plasma torch to inject a hot gas into the tuyeres to ignite the combustible material;
- and
- directing heat from combustion of the combustible material into the reactor vessel to preheat the reactor vessel, wherein flue gas composition is monitored for verification of combustion up to an auto ignition temperature of the combustible material.
A method comprising:
- injecting a combustible material into a plurality of tuyeres in a wall of a reactor vessel;
- using a plasma torch to inject hot gas into the tuyeres to ignite the combustible material;
- and
- directing heat from combustion of the combustible material into the reactor vessel to preheat the reactor vessel, wherein the plasma torch is turned off when an auto ignition temperature for the combustible material is reached in the tuyeres.
