Small industrial boilers or SIB's are also known as steam generating units. As per the Indian Boiler RegulationsGas-Fired Boilers. Gas-fired boilers are one of the most highly-efficient and durable types of boilers. ...2) Oil-Fired Boilers. Oil-fired boilers are typically found in areas that have little or no access to natural gas.Any closed vessel exceeding 25 litres or 5 gallons in a capacity that is used expressly for generating steam under pressure, including any mounting or other fitting attached to such vessel that is wholly or partly under pressure when the steam is shut off, is referred to as an IBR boiler. a vessel in which water is boiled to generate steam. An industrial boiler usually consists of a system of parallel tubes through which water passes, suspended above a furnace.There are two basic types of boilers: firetube and watertube. The fundamental difference between these boiler types is which side of the boiler tubes contain the combustion gases or the boiler water/steam.

NON-IBR Boiler i.e. is a boiler which is not covered under Indian Boiler Regulation. Any boiler, which is not covered under IBR i.e. a steam producing vessel whose volumetric capacity is less than 5 gallons (25 liters) is a Non-IBR Boiler & produces steam below one kilogram per centimeter square design gauge pressure.IBR Pipe comes under Indian Boiler Regulations. Boiler Pipe manufacturers need to follow IBR rules (law of India) for design, manufacture, installation, and operation, the tubes which are not covered under Indian Boiler Regulation are NON-IBR Pipes.The IBR is a construction code including requirements for design, material and fabrication for equipment used in the manufacture of boiler and boiler parts for use in India.The volumetric holding of the steam generating coil is less than 25 litres, by virtue of which the boiler is exempted from Indian Boiler Regulations. Forced circulation, water tube & Reverse flow design enables the boiler to produce steam at full working within 3 to 5 minutes from cold start.
