This Is a New York City License

The High Pressure Boiler Operating Engineer license covered here is administered by the New York City Department of Buildings.

The license authorizes qualified individuals to operate high-pressure boilers in New York City. These professionals are responsible for much more than watching a pressure gauge. They need to understand the boiler, burner, feedwater, steam, condensate, draft, controls, safety devices, and auxiliary equipment as one operating system.

Basic Applicant Requirements

Before qualifying through an experience pathway, applicants must satisfy several general NYC DOB requirements.

• Be at least 18 years old
• Be able to read and write English
• Be fit to perform the work authorized by the license
• Meet the Department's character requirements
• Meet one of the approved experience pathways
• Pass the written examination
• Pass the practical examination
• Complete the background investigation
• Complete the final license issuance process

The Standard Experience Route Requires Five Years

One common route requires at least five years of qualifying experience within the seven years before the application date.

Qualifying experience can involve employment as a fireman, oiler, general assistant, journeyman boilermaker, or machinist working under the direct and continuing supervision of a NYC Department of Buildings licensed High Pressure Boiler Operating Engineer.

A Mechanical Engineering Degree Creates Another Route

Candidates with a recognized degree in mechanical engineering can qualify through a shorter experience pathway.

Current DOB requirements call for one year of experience operating and maintaining high-pressure boilers under the direct and continuing supervision of a NYC licensed High Pressure Boiler Operating Engineer.

That one year must fall within the two years before the application date.

Other Experience Routes Are Available

NYC recognizes several additional pathways for experienced boiler and power-plant professionals.

Current routes can include:

• Holding a qualifying engineer or U.S. Coast Guard Marine Engineer certificate for at least four years, plus required NYC boiler experience
• Five years supervising, caring for, operating, and maintaining a qualifying government steam-generating plant, plus required NYC high-pressure boiler experience
• Completion of an approved two-year apprenticeship plus three years of qualifying NYC high-pressure boiler experience
• A National Board of Boiler and Pressure Vessel Inspectors Commission held for seven years plus qualifying boiler experience
• A qualifying ASME High Capacity Fossil Fuel Operator credential plus qualifying high-pressure boiler experience
• Certain high-pressure boiler licenses from other acceptable jurisdictions plus qualifying operating, maintenance, or inspection experience

Because these routes have detailed timing and documentation rules, match your exact work history to the official DOB requirements before applying.

NYC High Pressure Boiler Written Exam Format

What Is on the Written Exam?

Inspection and Testing plus Operation and Maintenance account for 66 of the 110 questions. Those two categories alone represent 60 percent of the written exam.

That is a fairly large hint from the blueprint. Learn how the equipment operates, how it is inspected, and how you recognize whether it is operating safely.

Administration Is Worth 22 Questions

Boiler operation involves records and regulatory responsibilities as well as mechanical equipment.

The current Administration section includes general regulations, logbooks, and boiler tubes.

Review:

• Required boiler records
• Operating logbooks
• Inspection documentation
• Applicable NYC regulations
• New York State boiler requirements
• Responsibilities of licensed operating engineers
• Tube-related operating and maintenance concerns

Logbooks alone account for 11 questions in this section, so documentation is not just an administrative footnote.

Inspection and Testing Is Worth 33 Questions

Inspection and Testing is tied for the largest section of the written examination.

The current blueprint includes:

• Gauges
• High-pressure steam piping systems
• Boiler inspection
• Installation requirements
• Maximum allowable pressure
• Miniature boilers
• Operating adjustments
• Pressure tanks
• Boiler tests
• Boiler tubes
• Valves

Tubes receive seven questions in this section, while inspections account for five. Gauges, steam piping, and testing also carry meaningful weight.

Operation and Maintenance Is Another 33 Questions

This category gets to the heart of the operating engineer's job.

Review subjects involving:

• Hot-water boiler expansion tanks
• Low-water cutoffs
• Maximum allowable pressure
• Waste removal
• Boiler tubes
• Valves
• Boiler water
• Safe operating procedures
• Routine maintenance

Tubes contribute eight questions here, valves contribute six, and maximum allowable pressure plus water contribute five each.

Learn what normal operation looks like so abnormal operation becomes easy to recognize.

Repairs and Alterations Are Worth 22 Questions

Operating engineers also need to understand what can be repaired, what materials and methods are permitted, and how alterations affect safe operation.

Study:

• Joints and connections
• Approved materials
• Maximum allowable pressure
• Piping installations
• Pressure tanks
• Boiler tubes

Maximum allowable pressure alone accounts for eight questions in this category. Pressure is one of those subjects high-pressure boilers tend to take personally.

Understand Low-Water Protection

Proper water level is one of the most important conditions in boiler operation.

Candidates should understand the purpose of low-water cutoffs, how water is maintained in the boiler, and why firing a boiler under an unsafe low-water condition can create an extreme hazard.

Study the relationship between:

• Boiler water level
• Feedwater pumps
• Low-water cutoffs
• Level controls
• Burner shutdown
• Make-up water
• Deaerators
• Condensate return

Combustion, Draft, and Air Supply Matter

A boiler cannot make steam efficiently or safely without proper combustion.

Review:

• Fuel and air relationships
• Combustion air
• Draft
• Burner operation
• Ignition sequence
• Flame safeguards
• Combustion efficiency
• Stack conditions
• Safe burner shutdown

These topics are especially important because the practical exam includes Draft and Air Supply plus an Ignition Sequence exercise.

The Practical Exam Contains 15 Exercises

Current Practical Exam Topics

The practical is a strong reminder that this license is about operating a plant, not simply recognizing boiler vocabulary on a computer screen.

Learn How to Put a Boiler Online Safely

Starting and bringing a boiler online is one of the practical exam topics and an essential field skill.

Candidates should understand the sequence of checks involving water level, valves, fuel, draft, controls, ignition, pressure, steam piping, and the operating plant before adding the boiler to the system.

Study Blowdown, Water Treatment, and Deaeration

Boiler water affects efficiency, corrosion, scale formation, and equipment life.

Review:

• Boiler blowdown
• Water treatment chemicals
• Feedwater quality
• Scale
• Corrosion
• Dissolved oxygen
• Deaerator operation
• Condensate return
• Make-up water

Blowdown, chemicals, and deaerator operation all appear directly on the current practical examination.

The Written Exam Is Closed Book

Candidates cannot bring reference materials into the written examination.

That means the code books and technical textbooks should gradually become training tools rather than something you depend on for every answer.

1. Study one boiler system.
2. Close the reference.
3. Explain how the system works in your own words.
4. Describe what can go wrong.
5. Explain what safety devices should respond.
6. Answer practice questions without the book.
7. Check your answers afterward.

Which References Should You Study?

The current CPS HR examination page lists NYC codes, New York State boiler regulations, NYC rules, and two technical boiler books.

The current suggested reference list includes:

• 2014 NYC Administrative Code, Title 28
• 2014 NYC Mechanical Code, Chapters 10 and 12
• New York State Department of Labor Code Rules Part 14
• Rules of the City of New York, Title 1, Section 20, Piping Systems
• Rules of the City of New York, Title 1, Section 22, Pressure Tanks
• 1 RCNY 103-05, High-Pressure Boiler Inspection and Filing Requirements
• Steam Plant Operation, 10th Edition
• High Pressure Boilers, 6th Edition

Candidates can review the New York High Pressure Boiler Operating Engineer Exam Book Package for a study library built around these regulatory and technical subjects.

Current Exam and Licensing Fees

You Have 24 Months to Pass the Practical

After passing the written examination, candidates apply separately for the practical exam.

NYC currently gives candidates up to 24 months from written-exam notification to pass the practical examination.

Schedule the practical with enough room for unexpected delays. Boiler operators already have enough pressure in their professional lives.

What Happens After You Pass Both Exams?

Passing the exams does not automatically issue the license. Candidates then complete the NYC DOB background investigation.

Current documentation can include:

• LIC2 license application
• Supplemental Investigation Questionnaire
• Examination score report
• Notarized Background Investigation Questionnaire
• LIC62 physical examination form
• Experience Verification Forms from qualifying supervisors
• Social Security History of Earnings
• Government-issued identification
• Latest pay stub or W-2
• Applicable engineering, National Board, ASME, or outside-license credentials
• Child Support Certification

NYC DOB specifically states that Experience Verification Forms from a company's Human Resources department are not accepted in place of forms from qualifying supervisors.

The License Has a Three-Year Term

The current High Pressure Boiler Operating Engineer license term is three years.

NYC DOB currently lists a regular renewal fee of $45. A late renewal currently costs $95, which combines the $45 renewal charge with a $50 late fee.

Renewal documentation can include an updated physical examination plus boiler inspection certificates and employer affidavits when the licensee is responsible for operating high-pressure boilers.

Build Your Study Plan Around the Exam Blueprint

1. Start with Operation and Maintenance. It contains 33 questions and directly connects with practical boiler operation.
2. Study Inspection and Testing next. This is another 33-question category.
3. Review Administration. Logbooks and regulatory requirements contribute 22 questions.
4. Study Repairs and Alterations. Another 22 questions cover materials, pressure, piping, tubes, and pressure tanks.
5. Practice closed book. The real written exam does not allow references.
6. Train separately for the practical. Practice plant equipment and procedures instead of relying only on multiple-choice questions.
7. Practice abnormal operating conditions. Know how water, pressure, draft, combustion, pumps, and controls interact.
8. Complete timed four-hour practice sessions. Build the concentration needed for 110 questions.

Prepare to Operate the Whole Plant

The strongest High Pressure Boiler Operating Engineer candidates do not study individual components as unrelated pieces.

A feedwater pump affects boiler water level. Water level affects safe firing. Combustion depends on fuel, draft, and air. Steam pressure affects valves, piping, and connected equipment. Condensate affects feedwater. Water chemistry affects tubes. The deaerator affects oxygen removal. Controls and safety devices are watching the whole process.

Learn those relationships. Then practice explaining what should happen during startup, normal operation, shutdown, testing, blowdown, low-water conditions, feedwater problems, combustion problems, and pressure changes.

At the same time, organize your experience records. The Department has several qualification pathways, but each one has exact experience, supervision, credential, and timing requirements.
