These calculations are for approximation only.

A 30,000 lb/hr steam system had a Boiler Blowdown rate of 6% and Make-up Conductivity was 600 mmhos/cm. Make-up Alkalinity was 320 mg/l. Condensate Return was 60%, therefore, feedwater Conductivity was 240 mmhos/cm. By installation of the Model BMURO system, the Make-up Water to the Boiler system was improved to 30 mmhos/cm Conductivity. The resulting Boiler Blowdown rate was reduced to 0.3% while maintaining a Boiler Water Conductivity of 3,200 mmhos/cm. The below listed savings were achieved by the decrease in Boiler Blowdown rate.

• Annual Fuel Savings ($7.00/MMBTU) = $ 33,506
• Annual Water / Wastewater Savings ($3.00/Mgal) = $ 5,166
• TOTAL ANNUAL SAVINGS = $ 38,672
  Note: Boiler Chemical Savings are in addition to the above savings.
