Steam Boiler Inspection Services

What is Steam Boiler Inspection?

A Steam Boiler or Steam Generator is a closed vessel in which water is heated, vaporized, and converted into steam at a pressure higher than atmospheric pressure. Any closed vessel exceeding 22.75 liters in capacity, used to generate steam under pressure, qualifies as a steam boiler.

Applications of Steam Boilers

Steam boilers are widely used in:

• Locomotives and Marine applications

• Power Plants

• Food Processing Units

• Textile Industry

• Chemical Industry

• Medical Industry

Why Use Steam in Industries?

• Holds 5–6 times more heat energy than water

• High-pressure, high-temperature, and high-energy operations

• Easy to control

• Cost-effective

• Non-hazardous, environmentally friendly, and hygienic

• Compatible with a variety of fuels

According to the American Society of Mechanical Engineers (ASME):

“A steam boiler is a combination of apparatus for producing, furnishing, or recovering heat, together with the apparatus for transferring the heat so made available to the fluid being heated and vaporized.”

While the history of steam boilers includes many catastrophic accidents, modern boiler codes and automatic safety controls have significantly reduced incidents. Nevertheless, over 2,000 boiler-related incidents still occur annually worldwide.

Types of Boilers

The boiler type is defined by the relationship between water and fire:

1. Fire-Tube Boilers – Fire inside the tubes; water surrounds the tubes.

2. Water-Tube Boilers – Water inside the tubes; fire surrounds the tubes.

3. Sectional Boilers – Water in cast-iron sections; fire around the sections.

4. Heating Boilers – For building heating (steam or hot water).

5. Process Boilers – Also called industrial or power boilers, used for manufacturing, power generation, etc.

Essential Requirements for Steam Boiler Inspection

• Maximum steam output with minimum fuel consumption

• Desired steam generation rate

• Compact, lightweight, and transportable design

• Ability to handle fluctuating loads

• Quick start-up capability

• Low installation, operating, and maintenance costs

• Corrosion resistance and low deposit formation in tubes

• Compliance with Boiler Act safety regulations

Operator’s Responsibilities for Boiler Safety

• Maintain Normal Operating Water Level (NOWL)

• Never add water when the level is uncertain

• Regularly test safety and relief valves in accordance with local codes

• Follow SOPs and instructions from the chief engineer

• Monitor steam pressure or water temperature

• Test low water fuel cut-offs (LWCOs) and feedwater pump controls

• Blow down water column, sight glass, and try cocks

• Maintain burner, fuel temperature, and gas pressure

• Track fuel and make-up water consumption

• Monitor stack temperature

• Maintain a boiler room log with data and observations

Preventive Maintenance for Steam Boilers

10 Steps to Reliable Operation:

1. Know your equipment; refer to manuals and manufacturer instructions

2. Develop and maintain a comprehensive SOP manual

3. Use boiler log sheets to record routine tasks and abnormalities

4. Keep accurate maintenance records (repairs, replacements)

5. Monitor water consumption via make-up water meters

6. Track fuel usage for performance anomalies

7. Ensure adequate air supply for combustion and ventilation

8. Maintain clean and dry electrical systems

9. Practice good housekeeping in the boiler room

10. Follow OSHA-compliant safety practices and use proper PPE

FAQs

Q. What factors are considered when selecting a steam boiler?

• Power requirement and working pressure

• Steam generation rate

• Fuel and water availability

• Space availability

• Operating and maintenance costs

• Geographical location of the power plant

Q. What are the risks associated with boilers?

Boilers may pose safety hazards due to:

• Faulty installation

• Defective pressure relief systems

• Corrosion

• Poor maintenance

• Unapproved modifications

Potential risks include: explosion, projectile incidents, high-pressure injection injuries, and asphyxiation.

Q. What is the pH value of boiler feedwater?

The recommended pH value is 8.5 to 9.5.

Q. What does ESP stand for?

ESP stands for Electrostatic Precipitator.

Q. What is the function of a fusible plug in a boiler?

A fusible plug ensures safety during low water levels, preventing overheating and boiler failure.
