1. The Importance of Distribution

2. Manifold Position And Vapor Trail

3. Duct Air Temp And Vapor Trail

4. Air Flow Velocity And Vapor Trail

5. Humidification And Temperature Controls

6. Multiple Manifolds In Duct

7. Multiple Manifolds And Vapor Trail

8. Recommended Number and Spacing of Manifolds for Various Duct Heights

9. Design Guidelines: Boiler & Humidifier Combinations Boiler Gross Output Capacity Should be at Least 1.5 Times Total Humidification Load Water Softeners Should Be Used On Boiler Feed Water Condensate Return System Is Not Necessary (Unless Required by Circumstances)

10. Design Guidelines: Boiler & Humidifier Combinations Boiler Pressure Should Be 15 psig (1 bar) Or Less Automatic Blow-Down System Is Desirable Steam Supply Piping Should Be Insulated No Limit To Size Or Number Of Humidifiers From One Boiler

11. Steam Humidifier - Performance Vapor Quality Excellent –Steam Molecules are.0006 Microns –Humidifier Tests Indicate No Particles Less Than 3 Microns Turn Down - Up To 123:1 For Single Humidifier Response Time - Excellent

12. Steam Humidifier - Costs Equipment –100 LB/hr (45 kg/hr) = $2,200 –1000 LB/hr (450 kg/hr) = $5,500 Installation –Depends on Application Energy –100 LB/hr (45 kg/hr) = $0.50/hr Maintenance –1 Hour Per Unit Per Year

13. Steam Supply Options No Volatile Chemical Treatment Do Not Return Condensate –Not Much Condensate With Humidification Stainless Steel Return Piping Replace Return Lines When Corroded

14. Dedicated Steam System Separate Boiler(s) For Direct Steam Humidifiers –Not Cost Effective At 100 LB/hr (45 kg/hr) –But Can be At 500 LB/hr (225 kg/hr) or More –Plus Benefits of Direct Steam Injection
