Difference between IBR boiler and Non IBR boiler

This article contains the information on IBR boiler and Non IBR Boiler which are used to generate the steam.

What is Boiler?

Boiler is a closed vessel in which water or other fluids are heated until it boils or before boiling point to generate steam or vapour. The heated or vaporized fluid is then used for various process applications such as food processing industry, feed industry, textile industry, paper industry, building materials, metal smelting, heating engineering, etc.

What is IBR?

IBR is Indian Boiler Regulations which was created in 15th September 1950 in exercise of the powers conferred by section 28 & 29 of the Indian Boilers Act to consolidate and amend the law. It governs design, manufacture, installation and operation of all steam producing vessels which fall under its purview. Under purview of boiler design, manufacture and construction need to follow the IBR Regulations. Boilers under operation need to be periodical Inspected by IBR authority.

As per the definition of IBR: THE BOILERS ACT

1. Any closed vessel exceeding 25 liters (5 Gallons)[ such capacity being measured from the feed check valve to the main steam stop valve] in capacity which is used expressly for generating steam under pressure and includes any mounting or other fitting attached to such vessel, which is wholly or partly under pressure when steam is shut off.
2. With equal to or more than One kilogram per centimeter square design gauge pressure and working gauge pressure.
3. IBR give set of Procedure, Rules & Standard for Industrial Boiler manufacturing & Maintenance.

What is Non – IBR Boiler?

Non – IBR Boiler is a boiler which is not covered under Indian Boiler Regulation.

1. Non-IBR boiler whose volumetric capacity is less than 22.75 liters (5 Gallons) and producing steam below one kilogram per centimeter square design gauge pressure and working gauge pressure.
2. Non-IBR boiler in which water is heated below 100’C.
3. The specifications and compulsions of IBR law do not apply to these boilers.
4. Need not to be inspected by IBR Authority.

Advantages of IBR Boiler :

• No risk of explosion.
• Legal compliance ensures peace of mind.
• Longer tube life & lesser breakdown.
• Safety Assurance.
• complete system is manufactured using IBR approved materials.

Advantages of NON-IBR Boiler : 

• Outside purview of IBR.
• No registration of boiler required at site.
• Ease of operation & preventive Maintenance.

What qualifies IBR?

The statutory requirements in India requires that design, manufacture, inspection, testing and certification of all types of boilers, boiler components, pressure vessels and piping which are to either generate steam or use steam or feedwater should be comply to the Boiler Act and Indian Boiler Regulation (IBR).
