IHI has been contributing to a stable supply of electricity through provision of the main equipment for thermal, nuclear and hydroelectric power systems.
IHI is one of the three major manufacturers in Japan in the field of boiler, which is the core facility in thermal power plants, and has supplied a lot of boilers to the domestic utility and IPP markets as well as overseas utility and IPP markets, such as Australia, Southeast Asia, North America, Europe, Middle East and China, including ten units of boilers with each capacity of 660 ＭＷ to Australia. IHI has even manufactured and constructed ultra-large scale boilers over 1,000MW for power generation. Furthermore, IHI is involved in the technology development and commercialization of high efficient boilers applying high steam conditions, as well as oxy-fuel combustion in order to reduce CO2 emissions from power plant.
Utilizing technological capability accumulated through the rich experience in this field, IHI has been supplying boilers for industrial use and independent power producers （IPPs） as well.
As for fuel, IHI has the technologies and experiences to utilize a wide variety of fuels, including fuel produced from waste materials, such as petroleum coke, residual oil and organic residues, and biomass in addition to coal, heavy fuel oil and natural gas. Also, IHI is developing the technology of Twin IHI Gasifier (we call it TIGAR), which will be able to produce syngas from Lignite Coal categolized in low – grade coal.
In addition, IHI provides a wide range of packaged boilers which are used as heat and steam source in various industrial facilities.
As a utility boiler manufactuer taking a major role in supply of stable electricity in the world, IHI has been making great efforts to meet the steam conditions required for improvement of plant efficiency. As a result, IHI has constructed the largest power output boiler in Japan and achieved the world’s highest steam condition.
IHI has a variety of boilers ranging from small or medium subcritical boilers up to large supercritical boilers that can accommodate a lot of types of fuels such as coal, heavy oil and gas. A wide range of IHI’s boilers helps and enables the customer to conduct a suitable planning of the required production facilities according to the customer’s purposes and needs.
Ｍedium and small scale boilers, commonly referred to as industrial boilers. These industrial boilers are used in various industries for the purpose of factory process as well as private power generation.
IHI has a large number of track records of supplying boilers for the domestic and overseas markets.
IHI boilers have high efficiency and high availability which contribute to stable power supply in many countries.
The first large-scale tower-type boiler in Japan was supplied by IHI. Due to the compact design, it was built next to the existing adjacent power unit continuously put in operation during its construction. This is another example of how IHI utilizes new technologies to meet the customer’s needs.

A heat recovery boiler (HRSG) used for combined cycle power generation.
HRSG generates steam by recovering the heat exhausted from gas turbine, and drives a steam turbine.
This is a boiler that effectively uses the vacuum residue oil and gas, which are by- products of oil refineries, to produce steam for the usage of power generation and factory processes. The plant shown in the above picture was fully equipped with environmental pollution preservation facilities.
This is a boiler for the world-first demonstration project which will produce almost zero-emission electricity
by adapting Oxyfuel firing technology to existing coal-fired power stations.
This ground-breaking technology enables CO2 to be ‘captured’ and stored deep beneath the Earth.
CFB is able to burn a variety of fuels, such as biomass, industrial waste, and low-grade coal, under faster fluidizing conditions.
Compact in size, but adaptable to many uses. Incineration can be finely controlled for economical and long-lasting operation.

In nuclear power operations, IHI supplies main components such as reactor pressure vessels, primary containment vessels, and piping systems. IHI is also involved in the development and construction of systems related to nuclear recycling. With regard to nuclear power plant equipment, IHI is supplying not only conventional boiling water reactors （BWRs） type, or advanced boiling water reactors （ABWRs） type, but also has started to supply pressurized water reactors （PWRs） type.
Steel vessels are used as primary containment for nuclear reactors and auxiliary equipment.
Vessels made by reinforced concrete with steel liners have also been used recently.
In this facility, highly radioactive liquid waste is mixed with molten glass, poured into stainless steel canisters, cooled, and then solidified.
This kind of pressure vessel for nuclear power plant constructed of extremely thick steel plate lined inside with stainless steel cladding.
When domestic power utility companies have nuclear fuel recycled abroad, high level radioactive waste is vitrified. This vitrified waste is received by and stored in this facility.
IHI is supplying power generation equipment and combined heat and power equipment using gas turbines derived from aircraft jet engines, gas engines and diesel engines to both Japanese and overseas clients.
By using a efficient and reliable engines and turbines in the core of the plant, it has realized stable energy supply, reduction of CO2 and energy cost, and energy consumption.
These are 100 MW class power plants that combine two LM6000 gas turbines, two heat recovery steam generators and one steam turbine to produce the world's most efficient power generation, and best environmental performance and reliability.
These are 20 to 30 MW class power plants that use the high efficient and very reliable gas turbine, LM2500 that is derived from a lightweight and compact aero engine.
These are 4 to 6 MW class and IHI original co-generation systems that can change the output of both power and heat (steam) according to demand. If there is surplus steam, it can be converted to electric power output to recover the energy.
The 400 kW to 5,800 kW gas engine series can operate in high efficiency using natural gas and city gas, as well as low calorie gases generated in the gasification melting furnaces, etc., therefore, it contributes greatly to CO2 reduction.
Diesel engines are often used in non-utility generation equipment that is run on a heavy fuel oil as well as diesel oil.
These are typical energy-saving systems that generate 2 MW of power and 6 tons of steam per hour by combining our original designed and developed high-efficiency and low NOx type gas turbine, IM270 and a heat recovery steam generator.
