Power Plant Engineering 2.15 High Pressure Boilers, , , , , , 2.14 INDIAN BOILER REGULATION ACT, , ¢ IBR means “The Indian Boiler Regulations Act 1920”., , ¢ = It is an Act of Law: “/t governs the manufacture, installation, operation and maintenance of Steam Boilers"., , ¢ In the early 1900's, steam boilers were widely used for industrial purposes., , ¢ Simple control systems and high steam pressures were the causes of accidents during operation. To, prevent such hazards and explosions, some rules and regulations were introduced as mandatory to, follow by industrial sectors., , ¢ In India, IBR Act was established, which specified that, a Government Inspector would be responsible and, would have to certify all steam boilers as ‘suitable’ from the safety point of view., , e Every part of IBR approved steam system has to be manufactured, installed, tested, operated and, maintained under the watchful eye of local inspector., , ¢ Every customer, who runs an IBR boiler, must carry out an annual IBR inspection in presence of an IBR, inspector., , ¢ The local IBR office is a state government department, and maintains satellite offices close to each, industrial zone, and they have to be invited to inspect the boiler and the relevant system., , ¢ The State Government may appoint qualified persons as Chief Inspector, Deputy Chief Inspectors etc., They may define the local limits, within which, each appointed Inspector shall exercise the powers and, perform the duties conferred and imposed on Inspectors under this Act., , IBR Boiler and IBR System:, , ¢ In the IBR act, a steam boiler is defined as, “a vessel containing greater than 22.5 litres of water, which is, used to generate steam”., , ¢ Generally, any boiler having capacity more than 1000 kg/hr is an IBR boiler. Note that, no pressure is, specified in this regulation., , ¢ The Act defines anything concerned to an IBR Boiler as an IBR system., , ¢ For example: Boiler mountings, Steam distribution pipes, Valves, Traps, Strainers etc., , Meaning of IBR for a Manufacturer of Steam Equipment:, , e An IBR license is required to manufacture steam equipment., , ¢ This is a factory approval, even before, the company starts manufacturing valve or pipe etc. This license is, also given to workshops, where adequate infrastructure for pressurized joint welding and testing is, available., , , , , , ¢ The product drawing is submitted for provisional IBR approval along with the necessary fees paid., , ¢ Once the approval is received, raw materials have to be purchased from IBR approved vendors. Also,, readily bought out parts must have an IBR approval certificate., , ¢ The inspector has to be called to inspect and approve the material before manufacturing., , ¢ The manufacturing can now be started. The manufacturer must use welding methods and fabrication, procedures as specified by IBR., , ¢ Before commencing manufacture of a boiler or boiler component, every manufacturer shall engage an, Inspecting Authority for carrying out inspection at various stages of manufacture as per I.B.R. regulations., , ¢ The Inspecting Authority shall follow necessary procedure for inspection and certification of boiler or, boiler component., , ¢ If inspector finds the boiler or the boiler component conforming to the standards prescribed by, regulations, he/she shall issue a ‘certificate of approval’ and stamp the boiler or boiler component. But,, if inspector finds the boiler or boiler component not conforming to the standards prescribed by, regulations, then ‘certificate of refuse’ has to be issued for non-conformance. Provided that, no, certificate shall be refused unless the Inspecting Authority had informed the manufacturer to carry out, necessary modifications or rectifications. But, if inspecting Authority finds that, inspite of giving
