A FLAMELESS COMBUSTION HEATER

摘要

A flameless combustion heater (10) is described, that comprises an oxidation conduit (14) and a fuel conduit (12) positioned within the oxidation conduit to form an oxidation zone (13) having an inlet (26) and an outlet (30), said fuel conduit having a plurality of openings (20) that provide fluid communication from within the fuel conduit to the oxidation conduit wherein the longitudinal axis (22) of at least one opening forms an oblique angle with the inner surface of the oxidation conduit. A method for providing heat to a process conduit is also described.
