SPX Heat Transfer Inc. was awarded a contract worth more than $25 million to supply feedwater heaters and spare parts to three supercritical coal-fired power units in India.

The agreement was signed with OJSC Power Machines, which has been tasked with the design, engineering, construction and installation of the BARH Phase I projects. The systems are being built for Indian energy company National Thermal Power Corp. BARH Phase I units 1, 2 and 3 are expected to generate a combined 1,980 MW of power.

Plans call for SPX Heat Transfer, a subsidiary of Charlotte-based SPX Corp., to manufacture the feedwater heaters at its main facility located in Tulsa, Okla., and ship the units to India.

“This is SPX Heat Transfer’s second major order for India since we set out to…establish a presence in the rapidly expanding Indian market,” says Drew Ladau, SPX segment president. “We are pleased to continue our collaboration with OJSC Power Machines, and look forward to expanding our operations in India and other areas of the world where there is a demand for increased energy.”

The plant uses supercritical steam generation, with water being converted directly into steam without passing through the boiling phase. The feedwater heating component pre-heats the water and facilitates a more gradual heat transfer, thus improving the thermodynamic efficiency of the entire system.
