As this type of system can be installed close to the burners, the ‘lag time’ for oxygen analysis – the measurement delay due to sensor response – is minimised, giving operators a comparatively short response time. Detailed burner performance can be also monitored by installing multiple analysers across banks of burners; this is especially important in fired heaters where low NOx burners are fitted, as the burners are notoriously difficult to evaluate through visual inspection since the flame is non-luminous. The outputs of these analysers can then be averaged to give oxygen trim control. Many systems also offer the option of fitting an additional carbon monoxide or combustibles catalytic sensor. This offers additional diagnostic benefits for process and burner optimisation, including providing early indications that excess air levels are too low, or that a bank of burners is incorrectly set–up, adversely affected by other burners, or suffering from nozzle blockage.”
