Understanding Kiln Efficiency:  Understanding Kiln Efficiency Dan O’Brien Harrop Industries, Inc. Columbus, Ohio Purpose :  Purpose Identify and quantify the specific areas effecting the energy consumption required to produce a product Definition of Kiln Efficiency:  Definition of Kiln Efficiency The theoretical energy required to dry/heat a product compared to the actual measured energy to dry/fire the product Units of Measure:  Units of Measure BTU per Pound of Fired Ware Pounds of Air per Pound of Fired Ware Get the Facts:  Get the Facts Focus on the Vital Signs:  Focus on the Vital Signs Vital Signs Contributing to Energy Consumption:  Vital Signs Contributing to Energy Consumption Live Load/Dead Load Temperature Profile Pressure Profile Oxygen Profile Air Injected Air Infiltration Gas Injected Energy Exhausted Radiation Losses Live Load: Mass of Ware being Fired (Pounds per Hour):  Live Load: Mass of Ware being Fired (Pounds per Hour) Live Load: Mass of Ware being Fired :  Live Load: Mass of Ware being Fired Dead Load: Mass of Car Furniture/Car Top (Pounds per Hour) Temperature Profile :  Temperature Profile Hand Held Pyrometer:  Hand Held Pyrometer Optical Pyrometer:  Optical Pyrometer Traveling Thermocouple:  Traveling Thermocouple Temperature Pressure :  Temperature Pressure ld Manometer:  ld Manometer Temperature Pressure Oxygen :  Temperature Pressure Oxygen Oxygen Analyzer w/ Ceramic Lance :  Oxygen Analyzer w/ Ceramic Lance Temperature Pressure Oxygen Air Flow :  Temperature Pressure Oxygen Air Flow Velometer:  Velometer Pitot Tube:  Pitot Tube Temperatures to Collect:  Temperatures to Collect Traveling thermocouple data Temperatures to Collect:  Temperatures to Collect Traveling thermocouple data Exhaust gas temperatures Temperatures to Collect:  Temperatures to Collect Traveling thermocouple data Exhaust gas temperatures Ware exit temperature Temperatures to Collect:  Temperatures to Collect Traveling thermocouple data Exhaust gas temperatures Ware exit temperature Under car temperature Temperatures to Collect:  Temperatures to Collect Traveling thermocouple data Exhaust gas temperatures Ware exit temperature Under car temperature Exterior Surface temperatures Pressure:  Pressure Measure interior kiln pressure profile from entrance to exit of kiln Oxygen Monitoring Sites Exhaust Fan Preheat Section Firezone Early Cooling Waste Heat oxygen:  Oxygen Monitoring Sites Exhaust Fan Preheat Section Firezone Early Cooling Waste Heat oxygen Vital Signs:  Vital Signs Kiln Flow Measure pounds or cubic feet of all gases injected into or exhausted from the kiln system:  Flow Measure pounds or cubic feet of all gases injected into or exhausted from the kiln system Combustion Air Combustion Gas Cooling Air Air for Jets Dilution Air Vital Signs:  Vital Signs Dryer Kiln Kiln Dryer The System Leak Factor is Applied to Balance the System Mass Flow:  The System Leak Factor is Applied to Balance the System Mass Flow Slide34:  Thermal Balance Diagram How are the Results Used?:  How are the Results Used?
