Tanks with Submerged Coils

Tanks with Submerged Coils

Tanks, large and small have been successfully converted to venturis for decades.

Sizing the Orifice of a Venturi for Optimal Performance of a Tank with Submerged Coils

The following factors are taken into consideration when sizing the orifice of the venturis on submerged coils:

  • What is the rated capacity of each coil? (Use manufacturer specs: BTU rating or use coil material and dimensions to calculate the load)
  • What is the steam pressure?
  • Is the tank regulated and a drip leg present before control?
  • How is condensate return currently handled? Is there lift in the return or is the condensate gravity fed to  the receiver? What is the condensate receiver back pressure? What is the lift to condensate return in feet/ meters? What is the diameter of return line?
