Japan’s Mitsubishi Heavy Industries (MHI) has won an order to supply core components for two sets of a 660 MW supercritical coal-fired boiler and steam turbine to be installed at an Indian power plant.

The components will be fitted in two new high-efficiency coal fired units at Chhabra power station, approximately 300 kilometers south-southwest from Jaipur.

The plant is owned by RRVUNL and the new units are due to be operational in 2016.

The boilers and turbine generators will be built and supplied by L&T-MHI Boilers and L&T-MHI Turbine Generators, two joint ventures set up by MHI in conjunction with Larsen & Toubro, India’s largest construction company and heavy machinery manufacturer.

MHI will manufacture the core components of the boilers and turbines while Mitsubishi Electric Corp will supply the core generator components.

RRVUNL was formed in 2000 when the Rajasthan government unbundled its state electricity board into five companies, including RRVUNL.

● Meanwhile, Mitsubishi Power Systems Americas (MPSA), the business base for MHI’s power systems operations in the US, has successfully completed verification testing of a large-scale selective catalytic NOx reduction (SCR) system.

The system is to be installed at an 800 MW large-size gas turbine simple-cycle power generation plant.

The testing was carried out at the Marsh Landing Generating Station in the San Francisco Bay Area, California, which operates on four Siemens 200 MW gas turbines, and MPSA said its SCR system reduced gas emissions, including nitrogen oxides (NOx) and ammonia, within compliance limits.

MPSA said the testing marked “a milestone achievement for the SCR system, demonstrating its capability to meet emission limits with a 200 MW class simple-cycle gas turbine”.

MPSA said its SCR system “successfully demonstrated the ability to keep within emission limits during quick starts and load changes and with gas turbine loads across the entire zero to100 per cent range”.
