Boiler Efficiency Technician Boiler combustion efficiency calculations trip up most test-takers, particularly when accounting for stack temperature and excess air ratios simultaneously. Many candidates memorize efficiency formulas but falter applying them to real flue gas compositions. Expect detailed scenarios requiring you to identify why burner isn’t meeting design specifications?and distinguish between problems stemming from fuel quality versus air supply miscalibration.
