Waste-to-Energy Industry
Working within tight environmental guidelines, waste-to-energy incineration plants utilize the most advanced technology—not only to dispose of waste, but to also generate electricity.
Konecranes Americas has a strong track record in the waste-to-energy field, with a portfolio of projects completed throughout Europe, Asia, and the Americas. We adapt our technologies according to the requirements of local authorities and the types of waste supplied.
Waste-to-energy cranes typically operate in the harshest of environmental conditions. Konecranes supplied the United States with its first poultry litter fueled power plant in Benson, Minnesota. This landmark project will convert a year-round stream of poultry litter, approximately 700,000 tons per year, into 55MW of electricity. The plant supplies power to 55,000 households and resolves serious environmental concerns for Minnesota residents.
Konecranes supplied four fully automated 20 ton CMAA Class "F" cranes positioned on two runways over bays that receive 3,260 tons of poultry waste five days per week. Each of the PLC-equipped cranes spans 70 feet and is linked to a control room and a computer, which commands motions of the bridge, trolley, and hoist.
A sophisticated automation design developed by Konecranes is used to solve fuel-quality issues. The cranes are equipped with a specially-designed electro-hydraulic bucket used for transporting materials which vary in terms of their moisture content. The crane then mixes allotted amounts of the designated materials to achieve uniform moisture content in the final fuel configuration.
The cranes are optimized with special features for the highly corrosive environment. Positive pressure within the electrical cubicles prevents unwanted residue from entering. Walkways are constructed of grating to protect against dust accumulation, and stainless steel fasteners are used throughout. The four cranes are identical to standardize service and reduce the number of spares required.
This plant is only one of many custom solutions developed by Konecranes for the world's growing waste-to-energy market.
