This course is designed to familiarize participants with general operator responsibilities associated with operating a furnace. After completing this course, participants should be able to identify instrumentation used to monitor furnace operating conditions and explain the basic operating principles, temperature control systems, and process fluid control systems. They should also be able to identify conditions that should be checked during furnace operations and explain how to detect and respond to abnormal conditions.

Learning Objectives

By the end of this course, you will be able to:

• 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.

This course is designed to familiarize participants with basic procedures for starting up and shutting down a furnace. After completing this course, participants should be able to describe basic procedures for preparing a furnace for startup, establishing the flow of process fluid, and lighting the burners. They should also be able to describe general considerations and basic procedures associated with planned furnace shutdowns and unplanned, or emergency, furnace shutdowns.

Learning Objectives

By the end of this course, you will be able to:

• Describe the major operator responsibilities involved in preparing a furnace for startup.
• Explain how and why a furnace is purged.
• Describe how to establish the flow of process fluid in a furnace.
• Describe how to light gas burners, oil burners, and combination burners.
• Describe a typical startup procedure for natural draft and balanced draft furnaces.
• Describe a typical planned shutdown procedure.
• Identify furnace conditions that may require an emergency, or unplanned, shutdown.
• Identify typical emergency shutdown systems and equipment.

An important part of an operator’s job when working with any furnace is to make sure that the furnace is running efficiently in order to save fuel, maximize the amount o f heat that is produced, and minimize the amount of heat that is wasted. More importantly, careful furnace operation helps prevent explosions, injury, and damage to equipment.

Learning Objectives

By the end of this course, you will be able to:

• Identify the major parts o f a furnace. 
• Explain basically how a furnace produces heat. 
• Identify the major furnace systems. Combustion and Heat Transfer 
• State the requirements for combustion. 
• Identify three types of heat transfer. 
• Describe how heat transfer occurs in a furnace. Fuel Systems 
• Describe the major parts of a typical gas supply system. 
• Describe the major parts of a typical oil supply system. Burners 
• Describe the major parts and basic operating principles of a raw gas burner. 
• Describe the major parts and basic operating principles of a pre-mix burner. 
• Describe the major parts and basic operating principles of an oil burner. 
• Describe the major parts and basic operating principles of a combination burner Air Flow, Part 1 
• Define the terms “draft” and “excess air.” 
• Describe the basic operating principles of a natural draft furnace. 
• Identify problems related to improper air flow. 
• Explain how draft and excess air are controlled in a natural draft furnace. Air Flow, Part 2 
• Describe the major parts and basic operating principles of a forced draft furnace.
• Describe the basic operation of an air heater. 
• Describe the basic operating principles of a balanced draft furnace. Process Fluid Flow 
• Explain how process fluid circulates in a furnace. 
• Identify problems associated with improper process fluid flow.

Furnaces are an important source of heat for many industrial facilities. Furnaces, which can also be referred to as fired process heaters, are basically enclosed structures that produce heat by the combustion of fuels. This course will review the major components that make up furnaces, explain how combustion takes place inside a furnace, and identify the different flow paths inside a furnace.

• Identify major parts of a furnace.
• Identify major furnace systems. 
• Explain basically how a furnace produces heat.

Combustion

• State the requirements for combustion.
• Identify three types of heat transfer.
• Describe how heat transfer occurs in a furnace.

Furnace Flow Paths

• Define the term “draft.”
• Describe the basic operating principles of a natural draft furnace.
• Explain how draft is controlled in a natural draft furnace.
• Describe the basic operating principles of a forced draft furnace.
• Describe the basic operating principles of a balanced draft furnace.
• Explain how process fluid circulates in a furnace.
• Identify problems associated with improper process fluid flow.
