A central heating plant may have one or more boilers that use gas, oil, or coal as fuel. The steam generated isused to heat buildings, provide hot water, and provide steam for cleaning, sterilizing, cooking, and laundering operations. Small package boilers also provide steam and hot water for small buildings.  \nA careful study of this chapter can help you acquire useful knowledge of steam generation, types of boilers pertinent to Seabee operations, and various fittings commonly found on boilers. The primary objective of this chapter is to lay the foundation for you to develop skill in the operation, maintenance, and repair of boilers.  \nObjectives  \nWhen you have completed this chapter, you will be able to do the following:  \n1. State the steam generation theory.  \n2. Describe boiler design requirements.  \n3. Describe the different types of boilers.  \n4. Describe the different types of boiler fittings and accessories.  \n5. Identify the automatic controls associated with boilers.  \n6. Describe the different types of instruments and meters.  \n7. Describe the procedures associated with boiler water treatment and cleaning.  \n8. Describe the procedures for cleaning boiler firesides and watersides.  \n9. Describe the procedures associated with boiler maintenance.  \nPrerequisites  \nNone  \nThis course map shows all of the chapters in Utilitiesman Basic. The suggested training order begins at the bottom and proceeds up. Skill levels increase as you advance on the course map.  \n\n| Utilities Equipment and Maintenance | | U\u003Cbr>T\u003Cbr>B\u003Cbr>A\u003Cbr>S\u003Cbr>I\u003Cbr>C |\n| --- | --- | --- |\n| Air Conditioning |  |  |\n| Refrigeration |  |  |\n| Heating Systems |  |  |\n| Steam Distribution Systems |  |  |\n| Boilers |  |  |\n| Sewage Disposal, Field Sanitation, and Water Treatment |  |  |\n| Prime Movers, Pumps, and Compressors |  |  |\n| Plumbing Fixtures |  |  |\n| Piping System Layout and Plumbing Accessories |  |  |\n| Structural Openings and Pipe Material |  |  |\n| Fundamentals of Water Distribution |  |  |\n| Basic Math, Electrical, and Plumbing Operations |  |  |\n| Plans, Specifications, and ColorCoding |  |  |\n\nFeatures of this Manual  \nThis manual has several features which make it easier to use online.  \n• Figure and table numbers in the text are italici","cbCaifmgyiqzfCC3","https://ap.wps.com/l/cbCaifmgyiqzfCC3","pdf",2971224,121,"English","# Overview\n# Objectives\n# Prerequisites\n# Topics\n## Steam Generation Theory\n## Boiler Fittings and Accessories\n## Types of Boilers\n## Boiler Design Requirements\n## Automatic Controls\n## Instruments and Meters\n## Boiler Water Treatment and Cleaning\n## Cleaning Boiler Firesides and Watersides\n## Boiler Maintenance","[{\"question\":\"What is the purpose of a boiler described in the chapter overview?\",\"answer\":\"A boiler is an enclosed vessel that heats and circulates water as hot water or steam to provide heat or power.
