1 Boiler HP = ~34.5 lbs steam/hr
From and at 212°F
100 HP = 3,450 lbs/hr
300 HP = 10,350 lbs/hr
500 HP = 17,250 lbs/hr
800 HP = 27,600 lbs/hr
1,500 HP = 51,750 lbs/hr
Standard FW Tank: 120-180°F
• No deaeration (most common)
Atmospheric Deaerator: 210-212°F
• Removes dissolved gases
Pressurized Deaerator: 227-240°F
• 5-10 psig operating pressure
24/7/365 Continuous: 8,760 hrs/yr
• Year-round operations
Seasonal (6-8 months): 4,380-5,840 hrs
• Oct/Nov to Mar/Apr typical
Note: Boilers operate continuously with reduced loading on nights/weekends, not on/off cycling
Ultra-Low: 8-15 psig
• Building heating systems
Low: 15-30 psig
• Light process applications
Medium: 100-250 psig
• Most industrial applications
High: 300-600+ psig
• Heavy manufacturing, power

Blowdown Rate (%): (Feedwater Conductivity - Condensate Conductivity) / (Boiler Conductivity - Condensate Conductivity) × 100
Water Savings: Difference in blowdown rates × steam production × operating hours
Energy Savings: Water savings × (Steam temperature - Feedwater temperature) × specific heat
Note: Calculations use simplified steam tables. For precise engineering calculations, consult ASME steam tables and account for actual enthalpies.

Note: Pennsylvania, New Jersey, and New York typically have 30-70% higher utility costs than traditional Midwest states due to aging infrastructure, higher regulatory costs, and limited pipeline capacity in the Northeast. Rates vary significantly by municipality and usage tier. Contact your local utility provider for exact rates.
