Radiant Coil Furnaces

Radiant Coil Furnaces are ideal for the process heating of liquids and gases to high temperatures over a wide range of operating pressures, where temperature and pressure combinations make traditional heating techniques impractical.  Wellman Furnaces has designed and built numerous Radiant Coil Furnaces for many different applications including:

  • Heating process streams of Silicon Tetrachloride and Hydrogen for Polysilicon production at temperatures to 1200°F (650°C) and operating pressures to 550 psig.  Wellman Furnaces' special control systems provide extremely precise temperature control even with variable flow conditions.
  • Heating air at 550 psig to 1700°F
  • Heating a mixture of natural gas and steam to 1000°F at 3100 psig.
  • Heating an acid to 1400°F (760°C) to catalyze a chemical reaction.
  • A four-coil unit, having a total heat capacity  of almost 2.0 MW, to heat a process chemical to 1040°F (560°C) at 700 psig. 
  • A two chamber system for the supercritical oxidation of organic material in waste water (SCWO) using a unique alloy to minimize corrosion at 4050 psig and 425°C.
