Novel pure-oxygen metal burner

Abstract

The invention discloses a novel pure-oxygen metal burner. The novel pure-oxygen metal burner comprises a metal burner body; an oxygen and steam channel is formed in the metal burner body; a cooling water channel for cooling the whole oxygen and steam channel is formed in the outer side of the oxygen and steam channel; a high-temperature resistant protective sleeve structure is arranged on the section of outer wall, close to the head of the burner, of the lower portion of the metal burner body; and a protective steam inlet is formed in the outer wall, near an inlet of the oxygen and steam channel, of the upper end of the metal burner body. According to the pure-oxygen metal burner, the defect that as for an original oxygen burner built by heat resistant pouring materials and corundum bricks, flames burn near the inner wall of a furnace is overcome, oxygen burning flames are concentrated on the vertical center line in a furnace hearth, and thus the situation that the economic loss is brought to an enterprise because of converter passive stopping resulted from the fact that the heat resistant pouring materials and the corundum bricks are often damaged by burning in a high-temperaturearea is avoided.

Description

technical field [0001] The invention belongs to the technical field of burners, and relates to a metal burner, in particular to a novel pure oxygen metal burner using a natural gas conversion process and a coke oven gas catalytic partial oxidation process. Background technique [0002] The burners in the prior art often burn out the heat-resistant castables and corundum bricks in the high-temperature zone, resulting in the passive shutdown of the reformer and bringing economic losses to the enterprise. [0003] Moreover, the burner of the prior art cannot guarantee that the burner can operate safely and stably for a long time in the flame high temperature zone of the furnace at around 1700°C. Moreover, when the load of the burner of the prior art changes during the process of starting and stopping, the oxygen combustion flame is unstable. This will cause tempering and ablation of the burner head, which will shorten the service life of the burner. Contents of the invention ...
