AI Overview
) to feed a sulfur burner, which generates
for subsequent
production. This unit typically uses steam-jacketed melting tanks, pumps, and pipelines to keep sulfur molten, with filters to remove impurities before feeding the burner.
Key Components of Sulfur Melting Unit
- Sulfur Melting Tank/Pit: Solid sulfur is fed into a tank where it is melted by internal steam coils.
- Steam System: Often uses waste heat steam produced later in the burning/conversion process for energy efficiency.
- Submerged Gear Pump: A steam-jacketed pump transfers molten sulfur to the high-level tank and then to the burner.
- Filter/Separator: Ensures molten sulfur is clean of impurities before entering the burner.
- Mass-Flow Meter & VFD: Used to precisely measure and control the liquid sulfur flow rate for stable concentration.
Production Process Flow
- Melting: Solid sulfur is melted in tanks heated to approximately .
- Filtration/Transfer: Molten sulfur is filtered to remove impurities and pumped through steam-jacketed piping.
- Storage: Liquid sulfur is kept in a high-level storage tank, maintained at a stable temperature, and prepared for combustion.
- Combustion: The molten sulfur is sprayed into a burner, reacting with dry air to produce gas.
