BP9 - Invest new boiler

Company name: THIEN LONG PAPER JOINT STOCK COMPANY
Address: Block C1, Tinh An Tay Industrial – Trade village Cluster, Tinh An Tay Commune, Quang Ngai City, Quang Ngai Province.
Project Summary: BIOMASS FLUIDIZED BED BOILER INVESTMENT PROJECT FOR ENVIRONMENTAL PROTECTION. The project objective is to reduce energy costs and greenhouse gas emission.
Year of implementation: 2017

Status before implementation

The main product of the factory is synthetic Kraft paper. During the manufacturing process, steam is fed into the drying rollers for paper drying. The factory's steam system includes:

  • One (01) boiler, with capacity of 3 tons/h, and acacia firewood as fuel
  • Boiler’s efficiency of 69 %.

     Existing Boiler                              Acacia wood

For the investment in a new paper corrugating line with a designed capacity of 4,200 tons/year, the factory planned to procure a biomass boiler with a capacity of 6 tons/hour.

Result

The factory intended to invest in:

  • One (01) biomass boiler with a capacity of 6 tons/hour.
  • Boiler’s efficiency of 81 %.

Investment in a biomass boiler helps save 12% of the energy compared to the existing acacia wood-burning boiler.
