Since manufacturing our first boiler in 1895, IHI Corporation has achieved world-recognised capability in the development of boiler technology. IHI has broad capabilities in designing, manufacturing and constructing a variety of boilers ranging from small packaged boilers through to ultra super-critical boilers with steam generating temperature of over 620°C, and a capacity of over 3000t/h for 1050 MW thermal power plants.

Details of the types of boilers currently manufactured by IHI can be reviewed here.

With an initial focus on the Japanese market, IHI Corporation has achieved a number of engineering milestones in boiler plant design, including:

  • 1971—first super-critical once-through boiler in Japan (600 MW)
  • 1980—first Stationary Once-Through Variable Pressure Reheat (SOVR) boiler in Japan (600 MW)
  • 1993—first Ultra Super-Critical (USC) boiler in Japan (700 MW)
  • 2000—world’s largest capacity USC boiler (1050 MW)

Through an extensive research and development programme, IHI continually strives to develop more advanced technologies in boiler design that deliver more efficient and environmentally sound outcomes.

IHI boiler designs feature Clean Coal Technology (CCT), which enables the use of coal more efficiently and economically, resulting in lower CO2 emissions and a better utilisation of the world’s limited natural resources. IHI’s accumulated technology is also used in other coal-fired power plant applications, such as De-NOx and De-SOx. IHI’s boiler design state-of-the-art combustion and burner engineering optimises plant efficiency and reliability.

Since 1980 in Australia, IHI has designed, manufactured and constructed 15 large pulverised coal-fired boilers with ancillary coal pulverising plant. These have included 10 x 660 MW boilers at three power stations in New South Wales (1982 – 1994), three super-critical boilers in Queensland—2 x 420 MW (2002) and 1 x 450 MW (2003), and 2 x 229 MW sub-critical boilers in Western Australia (2009).
