Sizing Steam Regulator for Pressurized Deaerator

Calculating for Regulator Steam and Size
1. Enter System Load expressed as any of the following units in the drop-down list. Boiler HP Sq. Feet EDR Lbs./Hour BTUs/Hour MBH GPM #1	One Regulator Design Amount of Steam lbs/hr Regulator Size inch #5 Two Regulator Design Amount of Steam in Spray Tray Area lbs/hr Regulator Size inch #5 Amount of Steam in Water Storage Area lbs/hr Regulator Size inch #5
2. Enter Temperature of Liquid to be Heated in degrees Fahrenheit. °F Blended Temperature calculator #2
Temperature inside tank is fixed at 227°F. #3
3. Select steam pressure available at regulator. Choose... 5 10 15 30 50 75 100 125 psi #4
Regulator amount of steam resulted in a value that exceeds a regulator size of 4 inches.
Press "Reset All" to CLEAR ALL calculations and enter new values.

Notes

1. System's load includes all boilers that may run at the same time.
2. The temperature (°F) of condensate returns and make-up water is returned to as blend temperature.
3. Represents temperature (°F) that the liquid is to be heated to.
4. Steam supply pressure cannot exceed 125 psig. If steam supply pressure available is above 15 psig, a pressure reducing valve must be used to reduce steam pressure down to 5-7 psig in the tank. A SPENCE Engineering Regulator comes standard with a pressure reducing valve.
5. Size is for a SPENCE Engineering Pressure Regulator (E2-D5 or E-D5), used on Pressurized Deaerators. Model E2-D5 used if steam pressure is 15 psig or less. Model E-D5 used if steam pressure greater than 15 psig and less than or equal to 125 psig.
