Abstract
A low firing rate oxy-fuel burner which may be comprised of commercially available standard components and which includes an oxidant conduit and a fuel conduit within the oxidant conduit. The fuel conduit has a fuel nozzle at the forward end thereof with a fuel swirler in the form of a twist drill positioned therein which is maintained in a an aerodynamically centered position by the flowing fuel stream. The oxidant conduit has an oxidant nozzle at the forward end thereof with an oxidant swirler in the form of helical spring position therein and surrounding the fuel nozzle.
Claims18
A low firing rate oxy-fuel burner comprising:
- a. a first conduit for the passage of an oxidant;
- b. a second conduit positioned within said first tube for the passage of a fuel;
- c. an oxidant nozzle attached to the forward end of said first conduit;
- d. a fuel nozzle attached to the forward end of said second conduit;
- and,
- e. a fuel swirler for said fuel mounted within said fuel nozzle, said swirler including an elongated member, said elongated member comprising a twist drill aerodynamically centered within said fuel nozzle by the fuel within said fuel nozzle.
A low firing rate oxy-fuel burner comprising:
- a. a T-member including a cross-bar portion with an inlet and an outlet and a stem portion with an inlet;
- b. an oxidant conduit for the passage of an oxidant attached to an outlet of said cross-bar portion of said T-member;
- c. a fuel conduit positioned within said first conduit for the passage of a fuel, and extending through said cross-bar portion of said T-member;
- d. an oxidant nozzle attached to the forward end of said oxidant conduit;
- e. a fuel nozzle attached to the forward end of said fuel conduit and positioned within said oxidant nozzle, and a fuel swirler for said fuel mounted within said fuel nozzle, said swirler including an elongated member, said elongated member comprising a twist drill aerodynamically centered within said fuel nozzle by the fuel within said fuel nozzle;
- f. a coupling for attaching an oxidant line attached to said inlet of said T-member;
- and
- g. a coupling for attaching a fuel line attached to the end of said fuel conduit which extends from said inlet of said cross-bar portion of said T-member.
