Boilers

IHI has been providing highly efficient and reliable coal-fired boilers which cumulate the state-of-the-art technologies to the world. Through coal-fired boilers completed on the basis of IHI’s clean coal technologies formulated by way of long term experiences and researches, we contribute to more effective and economical utilization of relatively low price coals. In the same time, we are supplying the domestic and overseas customers with boilers applicable to a variety of fuels as well as coal, and researches and development are underway to bring into markets oxy-fuel technologies to reduce carbon dioxide emission and a new gasification system and pre-dried technology to make possible good usage of lower rank coal like lignite, in addition to flue gas treatment facilities. We aim at early launch of those technologies.


Boilers

Large-scale utility boilers

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.

Boilers for IPP and PPS

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.

Industrial boilers

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.

Large-scale boiler for overseas utilities

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.

Large-scale tower-type boiler

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.

Heat recovery boiler for combined cycle power plant (HRSG)

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.

Vacuum residue oil fired boiler

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.

Boilers for oxyfuel power plant project

IHI is participating and positively involved in a world first pilot project which features introduction of oxyfuel firing technology, with CO2 capture and storage, to an existing coal fired power plant in such a manner to reduce CO2 to a level of almost zero.

Circulating fluidized-bed combustion boiler (CFB)

CFB is able to burn a variety of fuels, such as biomass, industrial waste, and low-grade coal, under faster fluidizing conditions.

Twin IHI Gasifier(TIGAR®)

IHI is developing coal gasification technology (TIGAR®) that can produce synthetic gas from low rank coal (lignite) to chemical feedstock.
In order to verify the product with high operability and reliability, IHI is planning to demonstrate 50 tons per day plant in Indonesia.
With this low rank coal gasification technology to consider unused lignites prevailing worldwide, IHI contributes to the effective utilization and diversification of energy resources.


Flue Gas Treatment System (Desulfurization (DeSOx) / Denitrification (DeNOx) Equipment)

Flue Gas Treatment System (Desulfurization (DeSOx) / Denitrification (DeNOx) Equipment)

In flue gas desulfurization plant, sulfur oxide (SOx) from exhaust gases emitted from factories or thermal power plants is absorbed so that byproducts such as calcium sulfate can be recovered. Supported by rich experience with large size flue gas desulfurization plant and power generators such as boilers, IHI has been delivering high performance equipment that can meet the recent, strict emission regulations. Flue gas denitrification plant uses ammonium(NH3) and a catalyst to decompose nitrogen oxide (NOx) in exhaust gases.
