Quality New Honeywell 51202789-901Module
Introduction
As an example we discuss the process inside a furnace: • If the main fuel valve is opened but the pilot burner is not ignited, the amount of fuel inside the burner chamber increases. • If the pilot burner ignites within 3 seconds after the inlet of fuel started, then the burner starts in a controlled way and the furnace is operational. • If the pilot burner does not ignite within 3 seconds, the amount of fuel inside the burner chamber increments to a critical level; if ignition should follow now, the furnace will be damaged. Instead the burner should be purged and the ignition process restarted. In this example the Process Safety Time (PST) is 3 seconds, meaning that if we detect –and respond to- the failure (no ignition of the pilot burner) within 3 seconds after opening the fuel valve, control can be regained by purging the burner chamber.
