We will always seek to break through such limits in current technology as large-capacity/downsized and highly-efficient and ultra-supercritical pressure technology and to provide the highest level of quality and reliable products and services across the world.
Toshiba's conventional power generation system that supports a worldwide, stable power supply
Toshiba supports a stable power supply by providing many highly-reliable, highly-efficient and eco-friendly systems with world-class technologies in Japan and other countries. Toshiba offers a seamless service for thermal power plant systems from R&D to design, manufacturing, sales, installation and maintenance, resulting in a reduction in cost for facilities and maintenance. Besides the above, we have strategic collaborations with the world's leading companies to strengthen our competitiveness and technological capabilities.
Thermal power generation for a stable power supply in response to variable power consumption
Thermal power systems generate electricity by rotating turbines and generators with the steam from water heated by burning fossil fuels such as coal, oil and natural gas in boilers. Thermal power generation has a role to ensure a stable power supply because it can control the power generation output by managing the heat energy in response to power consumption that varies to seasons or the time of day.
Major types of thermal power generation systems
Conventional thermal power generation ―uses a wide variety of fuels
A conventional thermal power generation system generates electricity by rotating steam turbines and generators with the steam from water heated in boilers in which fossil fuels (including coal, oil and natural gas) are burned. In comparison with combined cycle power generation, conventional thermal power generation can use a wider variety of fuels from inexpensive coal to clean natural gas.
Combined-cycle power generation―environmentally-friendly solution that has the flexibility to meet the demand of electricity
A combined-cycle power generation system generates power by combining two or more generating systems. The current mainstream type is to combine steam turbines with gas turbines and to also use waste heat that comes out of the gas turbines. This combination of two power generation cycles increases the efficiency of the plant, resulting in an eco-friendly system with low fuel consumption and low CO2 emissions. Compared to conventional thermal power generation, combined-cycle power generation systems can quickly start achieving an immediate response to power demand.
Toshiba's combined-cycle power generation to achieve the world's highest level of efficiency
Toshiba's combined-cycle power plant systems achieve the world's highest level of thermal efficiency by combining 1,600 °C-class high-efficiency gas turbines with high-efficiency steam turbines and generators and BOP (balance of plant) equipment.
Major thermal power generation equipment to pursue reliability and economy
Steam turbine
A steam turbine is a core machine in the power generation system to efficiently convert the heat energy of steam into mechanical energy (rotational energy). Toshiba is promoting development to achieve larger-capacity and downsized systems using the world's advanced last stage long blade while aiming at further increase in steam temperature to achieve early commercialization of higher-efficiency and 700°C-class ultra-supercritical pressure power generation system.
Turbine generator
A turbine generator is a machine to convert the mechanical energy (rotational energy) of a turbine into electrical energy.
Toshiba has been providing turbine generators with a wide range of capacities, from small to large ones, through continued technical development to meet social needs. Toshiba, especially, has enhanced the application of indirect hydrogen-cooled generators with higher efficiency and higher reliability. Furthermore, Toshiba is working on improving the operability of turbine generators to respond to the requirements of day-to-day grid operation.
Information and control system
The information and control system achieves a stable and efficient operation in power plants, secured response to complicated operation patterns and easy plant maintenance. Toshiba's information and control system provides comprehensive solutions as one system including not only the monitoring control system for boilers and turbines but also operation-/maintenance-related services for thermal power plants.
