Likeng II: Guangzhou, China

Babcock & Wilcox Vølund’s license partner Grantop (Guangzhou Environment Protection Investment Co. Ltd.) has completed the Likeng II waste-to-energy plant in Guangzhou, China. The plant is one of the largest Chinese waste-to-energy plants and it is specifically designed for Chinese waste. This includes the waste characteristics with high moisture and low calorific value.

The Likeng II plant has 3 lines of 750 tonnes waste capacity per day each, based on B&W Vølund engineering design and key components.

Scope of Supply

Babcock and Wilcox Vølund has supplied:

  • Basic design of boiler including technical assistance for construction and commissioning. Furthermore, a review of boiler detail design a review of boiler detail design and functional description for DCS.
  • Air-cooled Vølund grate.
  • Waste charging system with a feeding damper.
  • Feeding chute and feeding pusher.
  • Slag pusher.
  • Construction and commissioning advisors.

The Vølund Grate

The Babcock & Wilcox Vølund air-cooled grate is a longitudinal beam grate– a thoroughly proven design, highly suitable for continuous high-efficiency combustion of mixed household and bulk industrial waste with minimal emission of harmful substances and maximum energy recovery.
