ANDRITZ successfully starts up a new HERB recovery boiler at Naini Papers Limited, India

2021/10/29

International technology group ANDRITZ has successfully started up a new 550 t/d HERB chemical recovery boiler (upgradable to 700 t/d) at Naini Papers Limited in Kashipur, state of Uttarakhand, India.

The boiler is designed to handle a mixture of hardwood and agro-based black liquor and enables environmentally friendly and more energy-efficient operation compared to the black liquor incinerator previously used in the mill. Thus, the mill’s pulp production as well as the power-to-heat-ratio will increase substantially. The boiler also features a unique vertical air system to minimize air emissions.

The scope of supply also included:

  • Engineering for the entire system except civil work and the electrical and automation equipment
  • Complete pressure parts
  • Auxiliaries such as start-up oil burners, black liquor burners, and smelt spouts
  • Safety-related system (SRS)

Pawan Agarwal, Managing Director, Naini Papers Limited, says: “The entire ANDRITZ team has worked tirelessly and zealously to see to it that commissioning was trouble-free and fast. Team Naini conveys its warmest thanks to the ANDRITZ team for this wonderful support.”

This is the second of six ANDRITZ HERB recovery boilers currently being installed in India, thus showing the strong market share ANDRITZ holds in the Indian pulp and paper market.

Naini Papers is one of the leading paper brands in India and offers quality paper products from agricultural residue by using innovative, state-of-the-art technology, thereby providing an alternative to wood-based paper while conserving valuable resources and protecting the environment.
