Bharat Heavy Electricals dismisses Neyveli Lignite’s charges

Rejecting Neyveli Lignite Corporation’s charges that the boilers supplied to it had a design fault, Indian power equipment giant Bharat Heavy Electricals says it will run its two 125 MW power units in Rajasthan at full capacity for 15 days to show them the way to operate them and prove them wrong.

‘We have sorted out the issue and have given Neyveli Lignite the methodology of running the power units,’ said Jainender Kumar, executive director for project management with Bharat Heavy Electricals.

‘Next month we will run the two units at full load and give them the parameters to be followed in the future,’ Kumar told IANS over phone from New Delhi.

His reaction came after Neyveli Lignite chairman and managing director A.R. Ansari’s charge Friday that there is a design fault in the two 125 MW boilers supplied for its Rajasthan project. The units were commissioned June 2010 but started facing problems, thereby halting power generation for nearly a year.

‘We had told them that their boiler should be capable of handling lignite with an ash content ranging between 8-30 percent. They initially agreed but later was not able to meet the expectation. There is a design failure in their boiler,’ Ansari said.

In his response, Kumar said: ‘While burning the lignite, we encountered the problems of sintering (lump formation) which was not there in other boilers in India, including in Rajasthan. It is a unique problem confined to NLC’s units in Barsingsar.’

He said his company studied the sintering problem and suggested mixing red sand to solve the problem. ‘We also demonstrated that the mixing of sand will not corrode the boiler components,’ he added.
