Furnaces: Operating Conditions

Identify the instrumentation used to monitor furnace operating conditions. Describe the basic operating principles of furnace temperature control systems and process fluid control systems. Identify conditions that should be inspected during furnace operation. Explain how to detect burner problems and make the appropriate burner adjustments. Explain how to detect and respond to these furnace air flow problems: air leaks insufficient air flow and afterburning. Explain how to operate a furnace at reduced firing rates. Explain how to detect and respond to freeze-ups in the fuel supply system and process fluid system.
