Cyclone melting furnace and using method thereof

Abstract

The invention provides a cyclone melting furnace which comprises a furnace body and a fuel inlet, wherein the fuel inlet is tangentially arranged in the furnace body and is configured to introduce reaction fuel; and the furnace body is also provided with a guide gas inlet, and the guide gas inlet is arranged on a target area part, directly impacted by the reaction fuel, in the furnace body. According to the cyclone melting furnace, the reaction strength of the oxygen-enriched air and coke particles in high-temperature solid-containing gas is enhanced through arrangement of the guide gas inlet.

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 ...

AI Technical Summary

Problems solved by technology

[0004] The main problem is: the high-temperature gas containing coke particles in the burner enters the cyclone furnace tangentially. Since the temperature is as high as 1500 ° C, the air velocity is fast, and the strength of the cyclone furnace is high, the high-temperature particles will seriously wear the refractory material in the target area of ​​the cyclone furnace. , the use of high chromium refractory materials greatly reduces the operating life of refractory materials and increases the cost of operation and maintenance

This method increases the anti-wear performance of the target area of ​​the cyclone separator, but still exposes the target area material to the high-speed gas-solid flow, and does not solve the fundamental problem of the target area model of the cyclone structure
