L&T-MHPS Boilers Private Limited, a joint venture between Mitsubishi Hitachi Power Systems, Ltd. (MHPS) and Larsen & Toubro Limited (L&T) has received an order for two large-scale supercritical-pressure (Note) boilers (output: 660 megawatts [MW] each) to be installed in Unit 1 and 2 of a supercritical-pressure thermal power generation plant in Tanda, which NTPC Limited, a state-owned thermal power provider in India, is newly constructing. L&T is a leading construction firm and heavy machinery manufacturer in India. Handover and start of operation of the boilers are scheduled for July 2018 for Unit 1 and January 2019 for Unit 2. The order brings the total number of supercritical-pressure boiler ordered from India to MHPS to 11 units.
L&T-MHPS Boilers undertakes production and supply of the two units as well as their installation and commissioning at the site. MHPS will supply pressure parts, core components of the two large-scale boilers, to L&T-MHPS Boilers. The new thermal power plant will be built in the Tanda district of Uttar Pradesh state in northern India. When the new plant goes on stream, it will support the region's expanding power demand.
NTPC is India's largest power provider, accounting for nearly 25 percent share in the thermal power generation in India. Established in 1975, the company offers services in thermal power plant construction, operation and related consulting, and also engages in the development of hydroelectric power generation infrastructure.
As India has marked robust economic development in recent years, expansion in power generation capacity has been unable to keep pace with rapidly increasing demand, resulting in serious power shortages in some regions. To remedy this situation, the country has launched many large-scale projects to develop new power sources. Construction of the Tanda Power Plant is part of this broad initiative.
MHPS has a strong track record in supercritical-pressure and ultra-supercritical-pressure coal-fired power plants -- plants that not only realize outstanding efficiency in power generation but also help curb CO2 emissions.
Going forward, the company will continue to apply its superior technologies to meet increasing demand for coal-fired power generation plants not only in India but also in a broad range of countries and regions. Vigorous marketing will be carried out in these regions in a dual quest to achieve stable power supplies and also contribute to reducing environmental loads.
(Note) Note: Under normal atmospheric pressure (1 atm), water boils at 100°C (212°F/373°K) and the temperature and pressure go no higher. When increased pressure is applied, however, the boiling point rises beyond 100°C; and if pressure is increased further and takes the water temperature to 374°C/22.1 MPa (approx. 220 atm), water no longer boils but rather vaporizes. This is referred to as water's "critical point." Supercritical pressure is defined as the state when the pressure level has been increased to roughly 250 atm, driving the water temperature to 566°C; and ultra-supercritical pressure refers to the state when water's temperature rises to 593°C. In recent years, owing to their enhanced power generation efficiency, demand has been increasing for supercritical-pressure and ultra-supercritical-pressure boilers and steam turbines.
