Description
Technical field
The present invention relates to a kind of burner, relate in particular to and be used for gaseous state carbonaceous material partial oxidation and prepare synthetic gas (CO+H with swirler
2) nozzle.
Background technology
The gaseous state carbonaceous material is meant that Sweet natural gas, coke(oven)gas, coal-seam gas, refinery gas, associated gas etc. are rich in CH
4, C
2H
6Gas Deng hydro carbons.Along with the enhancing of people's energy and Environmental awareness, the gaseous state carbonaceous material (as coke(oven)gas, coal-seam gas) of some direct emptyings in the past and directly burning emptying has changed the industrial raw material with high added value into.With the coke(oven)gas is example, China is the world main coke production state, the coke(oven)gas of about 900 billion cubic meters of annual by-product, personal and be used for town gas, produce synthetic ammonia and the methyl alcohol except that melting down heating, the annual coke(oven)gas that directly enters atmosphere or burn in vain is equivalent to the West-East National Gas Transmission Project amount of natural gas in every year, and causes serious environmental to pollute.
The gaseous state carbonaceous material is converted into synthetic gas (CO+H
2) be an important step in the gaseous state carbonaceous material whole industry chain, the synthetic gas of production can be used for preparing fields such as chemical, liquid fuel, direct reduction iron making, hydrogen manufacturing.The main technique that the gaseous state carbonaceous material prepares synthetic gas has catalyzing part oxidation and non-catalytic partial oxidation, and common ground is that the nozzle that is installed on the converter is all played the part of very important role in whole conversion process.Nozzle should promote mixing of gaseous state carbonaceous material and vaporized chemical (air, oxygen-rich air, empty oxygen, water vapor, carbonic acid gas or its mixture of dividing); form suitable flow field with the body of heater coupling again; and then form suitable temperature distribution, reach the multipurpose of protection nozzle, refractory brick and catalyzer.
