An oxy-fuel burner () with monitoring including a fuel passage () terminating in a fuel nozzle (), a primary oxidant passage () terminating in an oxidant nozzle (), one or more sensors including a nozzle temperature sensor () for sensing at least one of an oxidant nozzle temperature and a fuel nozzle temperature, and a data processor () programmed to receive data from the sensors and to determine based on at least a portion of the received data the presence or absence of an abnormal burner condition including a potential partial obstruction of at least one of the primary oxidant passage () and the fuel passage () based on an increase or decrease in at least one of the oxidant nozzle temperature and the fuel nozzle temperature.

Burner with monitoring

A flat flame oxy-fuel burner including a gaseous fuel nozzle having a hydraulic diameter Dand a width to height ratio w/a of at least 2; a primary oxidant conduit surrounding the fuel nozzle to form an annular primary oxidant nozzle between the fuel nozzle and the oxidant conduit, the oxidant conduit having a height b, the respective outlet ends of the fuel nozzle and the oxidant nozzle being aligned; and a precombustor extending from the outlet end of the fuel and oxidant nozzles and having a length L and a hydraulic diameter D; wherein the ratio L/Dis non-zero and less than or equal to 4; wherein the ratio L/D, is non-zero and less than or equal to 12; and wherein the dimensions a, b, and w are sized to yield a primary oxidant Reynolds number from 200 to 22,000 during burner is operation at 0.05 to 1 MMBtu/hr.

Low-firing rate oxy-fuel flat flame burner with oxygen staging

A method for combusting oil from an oil-containing layer floating on water as from an oil spill or well leak. In the method, an oxygen-containing gas is passed through a conduit, the oxygen-containing gas from the conduit is introduced proximate the oil-containing layer floating on water, and oil from the oil-containing layer is combusted with the oxygen-containing gas in the presence of a flame. The oxygen-containing gas is introduced with an oxygen molar flow rate sufficient to decrease the opacity of a smoke plume from the combusting oil.
