Description

technical field

[0001] The invention belongs to the application field of cyclone melting furnaces, and in particular relates to a method for reducing wear of refractory materials of ultra-low volatile carbon-based fuels and waste cyclone liquid slagging furnaces by using the cyclone melting furnace. Background technique

[0002] High-temperature melting furnaces are widely used in many fields. In the high-temperature melting reaction of combustible gasification fine powder ash and ash, it can make the carbon with poor reactivity contained in combustible gasification fine powder ash and ash and oxidant in the Fully react under high temperature conditions, increase the carbon conversion rate, and obtain slag water-cooled crystallization to form a harmless glass body.

[0003] In the prior art, the burners are arranged tangentially on the side of the furnace. The cyclone melting furnace uses the high-speed rotating air flow to rotate the coal particles at a high speed and burn ...
