waste heat boiler in sulfur recovery unit

Molten salt heaters use molten potassium nitrate and sodium nitrite as heating media. Molten salt heater will heat the powder salt over the melting point until the viscosity of the molten salt allows circulating pump works, after the whole system is under circulating condition, then feed then into the thermal fluid heater for further circulating rising temperature to make it to be recycling used. Normal media working temperature is 400-550℃, top working temperature could reach 600℃.

Technical advantages

Digitized manufacture

  • The laying-off of steel tube adopts CNC 3D laser cutting machine.
  • The manufacture of square coil tube adopts CNC three-dimensional tube bending machine, no forced shaping.
  • The manufacture of serpentuator adopts serpentuator automatic production line, once-forming.

Long life span

  • The optimized radiation heating surface and convective heating surface, the medium flow is more reasonable, without overheat of the carrier and reduce the life;
  • Convection section: optimize convection heating surface and adopt effective fix and structural support to make its working life longer.
  • Set up effective flue gas partition for convection heating surface and cast partition to make it works longer.

Less fuel consumption

  • Use superior refractory brick to build inside and superior perlite in the middle. Keep the furnace temperature under 50℃ to make the minimization of loss.
  • Furnace adopts double close line coil, which makes heating surface sufficient.

Claus process - Wikiped

The Claus process is the most significant gas desulfurizing process, recovering elemental sulfur from gaseous hydrogen sulfide. First patented in 1883 by the chemist Carl Friedrich Claus , the Claus process has become the industry standard.

Thermo-kinetic modeling and optimization of the sulfu

Raising the steam pressure results in higher wall temperature in the waste heat boiler reducing the quantity of the heat transferred between the process gas flow in the waste heat boiler tubes and the cooling water in shell.

Differences between Simulators: Waste Heat Boiler Mode

The Claus Waste Heat Boiler (WHB) is a critical equip-ment item in any sulfur recovery unit (SRU). WHB failures have become increasingly common as higher sulfur feedstocks have found greater use and placed more load on the SRU. Such fail-ures are extremely costly when an out-of-service SRU either re-

Usually, DeNOx is incorporated in such installations, thus the process is termed the SNOX™ process. The SNOX™ process is more


Sulfur recovery unit Claus reaction furnace process outlet hot gas (2100-2800 °F) (1149-1538 °C) passes through the tubes of the two pass kettle type boiler. The waste heat from this gas is used to generate 600 psi (41 bar) saturated steam on the shell side of the boiler. Normally, the boiler tube metal is expected to remain
