Event Descriptions
"Burner Gas" (Center Gas)
-Firing with gas introduced inside burner for nozzle mix combustion. -Firing with gas introduced through the injectors for low NOx combustion. -Firing with oil introduced inside burner for nozzle mix combustion. -Firing with oil introduced through the injectors for low NOx combustion. -Low NOx firing with fuel introduced through the injectors. -Air, Fuel, and Exhaust Cycle Valves are closed. Pilot is on. -Exhaust Temperature Control Valve is driven to closed position.
"Injector Gas" "Burner Oil" "Injector Oil"
"LNI" (Low NOx Injection)
"Stop Cycle"
"Reject Exhaust"
"Cycle Fire" "Direct Fire"
-Regenerative firing.
-Non cycle firing. -(Exhaust Cycle Valve closed, Exhaust Temperature Control Valve closed, Air and Gas Cycle Valves open). -Burner(s) operates as conventional cold air burner(s). -Percentage of POC removed from the furnace through the TB-II exhaust system.
"Exhaust Extraction Rate" "Exhaust Reject Rate"
-Percentage of POC not taken through the TB-II exhaust system. -Switching from firing-to-exhaust and exhaust-to-firing.
"Cycle Reversal"
Other
"Air bypass valve"
-manual air valve used to counter residual exhaust suction when in stop cycle.
WARNING: Situations dangerous to personnel and property may exist with the operation and maintenance of any combustion equipment. The presence of fuels, oxidants, hot and cold combustion products, hot surfaces, electrical power in control and ignition circuits, etc., are inherent with any combustion application. Components in combustion systems may exceed 160°F (71°C) surface temperatures and present hot surface contact hazard. Fives North American Combustion, Inc. suggests the use of combustion systems that are in compliance with all Safety Codes, Standards, Regulations and Directives; and care in operation.
