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 620oC, and a capacity of over 3000t/h for 1050 MW thermal power plants.
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.
Development of HELE technologies
As a leading company in this field, and a pioneer in Ultra Supercritical (USC) coal-fired boilers, we have achieved one of world’s highest pressure and temperature steam conditions, and we continue to look for ways to improve plant efficiency. We are currently participating in the joint development of the Advanced USC 700degC -class boiler in order to achieve a plant efficiency of 46% (net HHV) and further reduce CO2 emissions. IHI’s supply records of major USC and Supercritical (SC) coal-fired boilers expands globally with over 20 major plants already been constructed or under construction. We offer various design options according to customer’s preference, such as output ranging from 300MW to 1100MW class, various types of fuel and operation and emission requirements.
IHI Projects in Australia
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).
