Conventional (Boiler & Turbine) Power Plants
Steam Power Plants use a variety of resources such as coal, oil and natural gas as fuel to generate power.
MHI group has an extensive record in meeting the global demand of conventional thermal power stations, including providing highly-efficient ultra-supercritical pressure boilers with an output of over 1,000MW. We also offer proprietary technology that enables the efficient burning of lignite (low-grade coal), which is deemed difficult due to its high water content. We also lead the world in the technology to keep clean the gas emitted from thermal power plants. Through our highly efficient thermal power and environmental technologies, we contribute to the world in ensuring the preservation of our environment while effectively utilizing fossil fuels for power generation.

Applying ultra-supercritical pressure technology for highly efficient power generation

We have an impressive track record in the field of supercritical and ultra-supercritical pressure coal-fired power plants and have achieved a high level of trust in the market due to the high efficiency and reduced emissions of these plants. Capitalizing on this advanced technology, we will contribute to the stable supply of electric power and to the reduction of environmental impact all around the world.

What is ultra-supercritical pressure?

Under normal atmospheric pressure [0.101 MPa], water boils at 100ºC. As pressure increases, the boiling temperature of water also increases. When the pressure reaches 22.12 MPa, and at a temperature of 374ºC, water no longer boils but converts directly into steam. This is called the critical point, and the pressure above this critical point is called supercritical pressure. Supercritical pressure with a temperature equal to or more than 593ºC is called ultra-supercritical pressure.

Co-generation Plants

Paving the way for effective use of energy
Co-generation plant is a power plant to supply both electric power and heat (in most cases steam). Co-generation plants are applied as effective solution for industrial purpose power plants to factories. Utilization of surplus energy from the factory as fuel for the boiler will further enhance effective use of the available energy. Industrial purpose power plants are also functional as distributed generations. We will contribute to optimization of energy usage and to the reduction of environmental impact, based on our advanced technologies.

Supplying power plants matching customers' needs

Engineering, Procurement and Construction (EPC) Services
Supplying power plants matching customers' needs
We are not merely a manufacturer that designs and manufactures the equipment and devices required for thermal power plants. We also provide EPC services, including plant construction.Power plants are consisted by Main plant equipment, such as boilers, steam turbines and generators, and miscellaneous auxiliary equipment. Since we are capable both on main equipment supplier and EPC, we are capable to optimize design condition for boilers, steam turbines and generators,based on the required electrical power and heat output. One strength lies in our engagement in design, manufacturing and construction of optimal plants in an integrated manner to ensure requirement of customer, suitability to location, with the maximized performance of the major equipment.
