2. The liquid sulfur is transported to a sulfur burner for combustion.
3. The furnace gas obtained by combustion is converted in the conversion tower (so2-so3 process), that is, the conversion section. In fact, high-temperature steam is very valuable in general technology, so a boiler is usually connected to the tail of the sulfur-burning furnace to generate high-temperature steam.
4. In the absorption tower, 98% concentrated sulfuric acid is used for absorption, which is the dry absorption section.
Note: the whole insulation system must be done well. In fact, the high-temperature steam generated by ordinary boilers is used to generate electricity and transport it to ammonium phosphate.
