HAUCK LONG NOSE STARJET BURNER LNSJ360 – LNSJ980

Interpretation of Gas Readings.Page 2GJ73FEEXAMPLEAssuming a drum gas analysis is taken at production rates.Readings Taken: O 2 - 4%CO - 2000 PPMCombustibles - 2%Problem: 4% O 2 - is too lowCO - is too highCombustibles are too highSolution: Gradually reduce fuel flow or increase air flow while watching O 2 , CO, andcombustibles. Typically the following will occur – O 2 will increase, CO willdecrease, and combustibles will decrease. Reduce fuel until minimal amountof combustibles are present. Then reduce fuel by a small amount for a safetymargin.NOTE: Typically some CO and combustibles will always be present.Variables Affecting the Combustion Process.1. Poor atomization of fuel: Atomizer contamination with particulate. Air passages clogged.2. Poor oil: Oil laden with particulate and unburnables.3. Switching fuels: Light to heavy oils, LP to butane.4. Flame shape.5. Stray air: Poor drum seals, larger than necessary feed openings, draft to high.6. Inadequate combustion zone.7. Material veiling thru flame: Interrupts burning, creating high CO and high combustibles.8. Overheating RAP or AC.9. Contaminated material.
