Embodiment Construction

[0009] As shown in the figure, a local oxygen-enriched flame heating elongated burner includes a burner body 1, a swirler 4 and an oxygen-enriched air duct 5, and the burner body 1 is provided with a gas pipeline 2 and Three oxygen-enriched air pipelines 5, a swirler 4 is installed on one side of the burner main body 1, the gas nozzle of the gas pipeline 2 is set at the position of the swirler 4, and a combustion air is provided under the burner main body 1 At the inlet 3, the combustion-supporting air is fully mixed with the gas at the swirler 4 and sprayed out to form the main flame combustion zone; the oxygen-enriched nozzles 6 of the three oxygen-enriched air ducts 5 are respectively located in the upper, middle and lower parts of the main flame combustion zone ;

[0010] A burner fixing plate 7 is also installed on the burner body 1 for fixing the burner body 1 and the oxygen-enriched air duct 5 .

[0011] The effect of each part of the present invention is respectively:...

Abstract

The invention discloses a local oxygen-enriched flame warming lengthening type combustor. The local oxygen-enriched flame warming lengthening type combustor comprises a combustor body, a swirler and oxygen-enriched air pipelines. A fuel gas pipeline and the three oxygen-enriched air pipelines are arranged on the combustor body, the swirler is arranged on one side inside the combustor body, a fuel gas nozzle of the fuel gas pipeline is arranged at the position of the swirler, a combustion supporting air inlet is formed below the combustion body, combustion supporting air is fully mixed with fuel gas at the position of the swirler and then ejected to form a main flame combustion area, and oxygen-enriched nozzles of the three oxygen-enriched air pipelines are located on the upper portion, the middle and the lower portion of the main flame combustion area respectively. The local oxygen-enriched flame warming lengthening type combustor has the advantages that on the basis of the physical principle, oxygen-enriched air is reasonably added in original flames which are not fully combusted for combustion supporting, molecules in the fuel gas and molecules in combustion supporting gas are reasonably matched, the temperature of the original flames rises by reasonably distributing and utilizing added oxygen molecules, fuel is fully combusted, and energy is saved by 25%-45%.

Description

technical field [0001] The invention relates to the field of fuel energy-saving products, in particular to a local oxygen-enriched flame heating elongated burner. Background technique [0002] In various roller kilns, tunnel kilns, and various boilers and other gas-fired boilers and kilns, natural gas, liquefied petroleum gas, coal gas, fuel oil, and alcohol-based oil are generally used as fuels, but there are always shortcomings of insufficient combustion, which makes the fuel There are varying degrees of waste. Contents of the invention [0003] In order to overcome the above technical problems, the present invention provides a partial oxygen-enriched flame temperature-increasing elongated burner, which reasonably adds oxygen-enriched air to the original insufficiently combusted flame for combustion. [0004] The present invention adopts the following technical solution to realize: a local oxygen-enriched flame heating elongated burner, including a burner body, a swirle...
