Columbus, OhioPurpose : Purpose Identify and quantify the specific areas effecting the energy consumption required to produce a productDefinition 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 productUnits of Measure: Units of Measure BTU per Pound of Fired Ware Pounds of Air per Pound of Fired WareGet the Facts: Get the Facts Focus on the Vital Signs: Focus on the Vital SignsVital 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 LossesLive 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 PyrometerOptical Pyrometer: Optical PyrometerTraveling Thermocouple: Traveling ThermocoupleTemperaturePressure: Temperature Pressure ld Manometer: ld ManometerTemperaturePressureOxygen: Temperature Pressure Oxygen Oxygen Analyzer w/ Ceramic Lance : Oxygen Analyzer w/ Ceramic Lance TemperaturePressureOxygenAir Flow: Temperature Pressure Oxygen Air Flow Velometer: VelometerPitot Tube: Pitot TubeTemperatures 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 temperatureTemperatures 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 kilnOxygen Monitoring Sites Exhaust FanPreheat Section FirezoneEarly Cooling Waste Heatoxygen: Oxygen Monitoring Sites Exhaust Fan Preheat Section Firezone Early Cooling Waste Heat oxygenVital Signs: Vital Signs KilnFlowMeasure 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 AirVital Signs: Vital Signs Dryer Kiln Kiln DryerThe System Leak Factor is Applied to Balance the System Mass Flow: The System Leak Factor is Applied to Balance the System Mass FlowSlide34: Thermal Balance Diagram How are the Results Used?: How are the Results Used?
