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.
Ranking as the cleanest, most efficient plant of its kind in the world, this engineered, designed, procured and constructed WtE facility reduces landfill volume by 90%.
The plant processes local residual household, commercial and industrial waste. It generates 7.25 MW of green energy, contributing to Peterborough Council’s Blue Sky project to provide sustainable energy in a smart city environment.
This plant is installed at the cardboard factory Örebro Kartongbruk AB, situated in Örebro, Sweden. The fuel consists partly of wet and dry fractions of waste from the cardboard factory and partly of unsorted industrial waste including plastic, wood and a fraction of uncombustible material.
Spray dryer absorber, pulse jet fabric filter and mercury control systems result in high SO2 removal efficiency and low operation and maintenance costs.
The W.H. Sammis plant is the largest of FirstEnergy’s coal-fired electric generating facilities in Ohio. The plant consists of seven coal-fired units totaling 2,220 MW and is located along the Ohio River.
The I/S REFA waste incineration plant in Nykøbing Falster, Denmark is jointly owned by 13 municipalities. The company collects and treats all kinds of waste from households and industries on the two islands of Lolland and Falster, a total of about 200,000 tons/year. The majority of the waste is either combusted or recycled.
PBREF No. 1 was awarded the American Society of Mechanical Engineers (ASME) 2009 Large Waste-to-Energy Facility Recognition Award for outstanding performance among facilities in North America.
B&W supplied the complete incinerator with state-of-the-art Waste-to-Energy technology which included waste crane, feed chute, feed grate and five-section combustion grate, combustion air system, auxiliary burners, ash conveyors for slag and fly ash from the boiler hoppers, feed water pumps with controls.
With a combustion capacity of 37 tonnes waste an hour (9.2 MJ/kg), the Högdalen unit is characterized by flexibility. The plant is capable of burning municipal solid waste (MSW) and industrial waste – mainly refuse-derived fuel (RDF). B&W’s supply includes a furnace/boiler with economiser, a complete ash/slag system and a system for transporting fly ash from the boiler rear pass.
This plant will supply approximately 43 MW of heat to the district heating network in Aalborg. The efficiency is approximately 100%, and the energy produced will supply some 16,000 houses with electricity, and 30,000 houses with district heating.
