Description

technical field [0001] The invention belongs to the technical field of gasification and cracking, and relates to a gasification and cracking device based on electric induction heating and a method for preparing high-temperature sulfur gas. Background technique [0002] The gasification and cracking furnace is a device used for gasification and cracking reaction of solid or liquid materials. For sulfur, waste sulfuric acid, organic matter, biomass, coal and other materials, the gasification and cracking process needs to be carried out in a high-temperature closed gasification and cracking furnace. [0003] Generally, the process requires the gasification and cracking furnace to quickly heat the reactants to a temperature of 300-1200 ° C or even higher to ensure short residence time of the medium, less side reactions in the process, high product yield, and stability and high efficiency. Heat supply and heat transfer, and economical and applicable high temperature and corrosio...
