Low Pressure Boilers Handbook: Principles, Operation, Inspection, and Code Compliance for Steam and Hot Water Heating Systems

By Engr Jared C. Downing

Most boiler operators never get the education they deserve. They are handed a set of procedures, told what to check, and sent into the boiler room. They know the checklist. They do not always know what happens when something on that checklist fails - or why. That gap is where emergencies happen.

The Low Pressure Boilers Handbook was written to close that gap permanently. This is the most comprehensive, code-grounded, field-oriented reference ever produced for the operators, engineers, and licensing candidates who work with low-pressure steam and hot water heating boilers every day. Across 13 fully illustrated chapters, you gain the technical depth to understand not just what to do, but why every procedure exists, what the physics behind it is, and what the consequences are when it is ignored.

Chapter by chapter, the handbook takes you through the complete professional knowledge base: the thermodynamics of steam and sensible heat; combustion chemistry and burner management systems; ASME Section IV construction requirements and the H stamp; safety relief valve selection, sizing, and the code reasons behind every installation rule; water treatment science and the chemistry of scale, corrosion, and oxygen attack; boiler room design, ventilation, and NFPA 54 combustion air requirements; startup, monitoring, shutdown, and emergency response procedures; inspection intervals, NBIC repair requirements, and what an authorized inspector is actually looking for; hot water hydronic systems and expansion tank physics; steam distribution, steam traps, and how a single failed-open trap can waste thousands of dollars in fuel every year; multi-boiler controls, outdoor reset, lead-lag sequencing, and BAS integration; systematic troubleshooting for every common failure mode from BMS lockout to waterlogged expansion tank; and a full licensing examination preparation chapter with 50 practice questions, 10 essential formulas, and safety device code quick reference.

The handbook includes over 50 original technical diagrams and equipment illustrations, 40 fully worked numerical examples with step-by-step calculations, more than 80 practice problems with complete boxed solutions, saturated steam tables from 0 to 15 psig, a daily operator log template, a 68-term professional glossary, and a comprehensive subject index. Every code reference cites ASME BPVC Section IV, ASME CSD-1, NFPA 54, NFPA 85, or the National Board Inspection Code directly.

This handbook is written for practicing engineers, licensed stationary engineers, building engineers, plant operators, inspection candidates, vocational instructors, and anyone preparing for a state boiler operator licensing examination. If you want to pass your exam, you need this book. If you already hold a license and want to know your plant the way a senior engineer knows it, you need this book. If you are responsible for a heating plant and you have ever found yourself hoping the problem goes away on its own, you especially need this book.

Stop operating on hope. Start operating on knowledge.
