DE1127886B - Apparatus for the production of acetylene by incomplete combustion of hydrocarbons with oxygen - Google Patents

Description

It is known for the purpose of producing acetylene by partial oxidation in gaseous or vaporous form To heat hydrocarbons with oxygen, the hydrocarbon and the oxygen separately, the two To mix gases and to react with one another in a flame reaction, with a burner block being arranged in front of the reaction chamber, which has a plurality has parallel channels through which the reagent mixture flows into the reaction chamber and there is ignited by means of a pilot flame. The reaction flame passes through the burner block stabilized and prevents the reaction flame from flashing back into the mixing chamber. It is further known, in the flow shadow created by the burner block in the hydrocarbon-oxygen mixture existing gas flow arise to introduce oxygen in order to maintain the pilot flame there.

It has now been found that you have a better stability of the reaction flame and thereby a Significant increase in throughput and better acetylene yield achieved when using a burner block used, in which the mouths of the oxygen lines are widened, so that cavities arise, which are open to the reaction space. For the design of the device according to the invention there are various possibilities. For example, there can be many individual cavities between the mouths the channels be arranged. One can also provide some large cavities, each cavity receives multiple oxygen supplies. Another option for designing the burner block consists in opening the mouths of the channels for the flow of the hydrocarbon-oxygen mixture can protrude on the side of the reaction chamber over the burner block, so that A single cavity is created between the mouths, in which a multitude of oxygen lines is created merge.

An older proposal concerns the use of combustion chambers to generate the pilot lights. The difference between the device according to the invention and the older proposal is that there Oxygen and a combustible gas are introduced into the combustion chamber through channels in which the Pilot flame is generated, while here only oxygen is introduced into the cavity. The pilot light burns here essentially outside the

Cavity because there is no combustible gas in the cavity.

In the figure, a device according to the invention is shown schematically, for example. By Channel 1 flows the hydrocarbon-oxygen mixture. As a result of vortex formation in this mixture behind the mouths of the channels 1, the incomplete combustion in the reaction chamber 4 is stabilized, the stability being improved through the cavities 3 into which oxygen flows through lines 2 will.
