Gas Quality Stakeholders’ Technical Committee Meeting

Gas Company TowerLos Angeles, CAJanuary 10, 2006

Industrial / Commercial Burners

> Area with least interchangeability data

> GTI is conducting a survey with California focus for 11-member sponsor group of – Work is currently underway– Expected completion of Jan. 31, 2006– Data to be input into CEC project

> CEC Project planned for 2006– GTI – industrial burner interchangeability testing– LBNL – appliance air quality

Task 1 – Industrial Burners> Burners

– Classification– Applications– Physical types– manufacturers

> California industrial gas use by industry> California burner population> Burner performance variables> Burner test protocols> Current range of California gas> Established current California gas ranges> Anticipated LNG and off-spec gas

Upcoming CEC Project

> Expected start in March, 2006

> Stakeholders committee to monitor usefulness of project results

> Technical advisory committee relying on expertise to assist project team as project proceeds

> Activities– Selection of performance variables, test

protocols, burners with control systems– Testing in GTI laboratory furnaces– Modeling of burner sensitivity to fuel changes

Major Affected Parameters

> Stability– Flashback, lift-off, blowout, pressure fluctuations

> Flame shape– Flame length and diameter

> Emissions– CO, NOx, UHC, VOC

> Burner noise> Flame heat release

– Flame and flue gas temperature, heat flux

> Turndown ratio

Burner Evaluation - Traditional> Flue gas and furnace temperature

– Suction pyrometer (aspirator)– Thermocouples

> Stability– Air pressure/noise fluctuation– Visual lift-off & flashback (premixed)

> Flame shape and length– Visual observation (template measurement)

> Heat release– Optical heat flux probe– Heat balance calculations

> Noise– Microphone

> Emissions– Gas sampling to external analyzers

Burner Evaluation - Advanced> Exhaust and furnace temperature
