HPGCL acknowledges poor quality Chinese equipment
The supply of poor quality Chinese equipment has been in news for long, but HPGCL has acknowledged it for first time, which was revealed in an RTI reply.

THE ALLEGED poor quality of Chinese equipments and workmanship at thermal plants built by Reliance Infra has been acknowledged by Haryana generation Power Corporation Ltd. (HPGCL).

As per information obtained under RTI by Gurnek Singh Brar, Chief Engineer Khedar thermal plant has apprised additional Chief Secretary Power in July about various instances of bursting/ damages of valves piping etc. due to poor quality of material/ workmanship at thermal plant, which have never been heard of in any other thermal plant of country.

It may be mentioned that at Yamuna Nagar thermal major equipment was damaged due to poor quality of material. Turbine blades of both units are under repair after extensive damage to them. Earlier unit was running at half load due to ESP problem for about one year. Turbine blades at Khedar were also damaged, which has now been repaired locally.

As per design 6 coal mills are required for full load operation of the unit. But actually 7 coal mills are being used even with the blending of imported coal. This has resulted in excess coal consumption. Thus, dwindling coal stock at the Khedar thermal plant is a cause of worry for HPGCL and may affect generation. According to sources, the thermal plant is practically running on hand to mouth coal stock and is dependent upon the daily receipt of coal rakes.

As per minutes of the meeting, difficulties are being faced by engineers in reading/ understanding the drawings of boiler, turbine and auxiliaries supplied by OEM China due to use of Chinese language at many places. HPGCL has decided to impart training to some of its engineers working at Yamuna Nagar to learn Chinese language so that they can easily interact with the representatives of Chinese firms and work is not hampered.

There is problem of spares for coal mills and proper blending of coal, forcing operation of seven coal mills to achieve rated load. HPGCL authorities are facing problems in procurement of spares of Chinese equipment.
