Base case
- A natural gas fired boiler provides 100 kg/h steam for 12 hours per day to run a sterilizer
- Seasonal efficiency of boiler is 70%
- Steam pressure is 220 psig at superheat temperature of 205 °C
- Condensate at 70 °C, no return
- Makeup water at 10 °C
- Decrease steam pressure and flow for sterilizer to150 psig and 60 kg/h
- Lower superheat temperature to 188 °C
- Recycle half the condensate
- Cost of change estimated at $30,000
- O&M savings: $400 per year
- Higher efficiency boiler
