Post Indian Independence.
In 1959, Naoroji partnered with the first Indian boiler manufacturing company, ‘Nestler’, based in Love Lane, Byculla, Bombay to provide Riveting and Manufacturing services. Naoroji’s son Rusi started manufacturing boilers in the Empress Welding Workshop, 1970 and by 1974 a mass of land was purchased at Vapi, Gujarat for Boiler manufacturing under a new name ‘Industrial Boilers.’

The manufacturing of the Vertical Cross Tube Boilers, which were fully riveted, commenced in 1978. This led to the production of Package Boilers of welded design.

with the advent of this technology, in 1986, Industrial Boilers enhaced as India’s first commercial Fluidized Bed (FBC) Boiler manufacturer, the company attained new heights with advanced models that were inaugurated at regular intervals.

By 1990, the ‘Agropak’, world’s first Hybrid FBC Boiler, a combination of a water wall tube furnace with smoke tube shell was developed In 1995, the ‘Brownian Motion Furnace’ boiler startled the industry from its roots with its capacity to burn almost all Bio and Residue fuels at utmost ease. Consecutively, Pith, Pattal, Bark, Roots and Cow dung were branded as Fuels.

21st Century.
Evidently, the Power Crisis in India was deepening and a large demand existed for small powerplants. Industrial Boilers launched a range o  small power generation boilers working on Biomass and Coal.

By 2002, Steam Turbine manufacturing was launched with a new company ‘IB Turbo’ at Greater Noida, NCR. Within 10 years IB Turbo launched five new Turbine frames to cater to the first time CoGenerator. Therefore, Industrial Boilers diversified into Hi-Tech products like Rotary Incinerators, Electrostatic Precipitators’ and Single Drum Boilers.
