Filbornaverket / Helsingborg, Sweden VØLUND™ WASTE-TO-ENERGY TECHNOLOGY PROJECT CASE HISTORY Plant Facts Treats approx. 200,000 tonnes of waste annually produced by inhabitants and businesses in the southern Sweden region Produces approx. 40% of the district heating water for 2,000 apartments and 8,500 villas in the Helsingborg district Produces electricity for 7,500 villas Steam conditions of 425 °C and 49 bar doubles the electrical efficiency of the former plant The Filbornaverket waste-to-energy plant in boiler with superheaters and economizers, electrical Helsingborg produces steam, district heating system, wet flue gas cleaning and flue gas cleaning and electricity. The plant was handed over to condensation system with a heat pump. the customer Öresundskraft in early 2013. The boiler is equipped with a water-cooled The main fuel for Filbornaverket is combustible DynaGrate® combustion grate and an advanced fractions of waste from households, industry combustion control system. The DynaGrate and businesses. The plant uses the region’s combustion grate is distinguished by its reliability large quantities of combustible waste to and fuel flexibility to accommodate both high and produce electricity and district heating for the low calorific fuels. local grid. To reduce maintenance costs, the boiler design also • Burns approx. 200,000 tonnes of waste per year includes water-cooled wear zones and panel walls • Thermal efficiency: 98% protected with Inconel® weld overlay. • Investment in the plant: 1.85 billion SEK Inconel weld overlay is a strong, corrosion- and Scope of supply oxidation-resistant material that forms a thick, Babcock & Wilcox Renewable’s (B&W’s) stable, oxide layer for surface protection. It is an project scope includes a VølundTM technology investment that provides considerable long-term combustion system with waste crane, steam financial benefits. continued RENEWABLE | ENVIRONMENTAL | THERMAL Sophisticated emissions control B&W Environmental supplied the GMABTM flue gas cleaning and energy recovery systems together with Alstom Power Sweden AB. The latest technology for emissions control allows Filbornaverket to achieve very low emissions levels — about half of what the EC Directive and the Swedish regulatory requirements specify. Photography: Fagerhult Improved revenue and reduced greenhouse Plant Data gas emissions are some of the benefits that Process parameters Values Units come from extended energy recovery by R1 value 1.41 – condensation of the hot flue gases. In addition, Waste capacity (MCR) 27 t/h energy recovery offers an economic incentive Heat value, lower 10 MJ/kg since the generated heat can be sold while improving the overall flue gas treatment. Steam output 88.7 t/h Steam temperature 425 °C The boiler, the combustion cleaning and flue Steam pressure 49 bar gas cleaning systems are designed and project Gross electric output 17 MW managed by in-house resources. The diversity of our capabilities allows us to provide a District heating output 58 MW complete technology solution more efficiently Boiler outlet flue gas temp. 160 °C and with higher quality.
