Waste-to-energy
Doosan Lentjes designs and builds processes and technologies for the waste-to-energy sector. Around 77 Doosan Lentjes units are in operation around the world, converting more than 9 million tonnes of waste to energy every year.
The company specialises in bespoke air and water-cooled grate combustion chamber systems tailored to the precise waste types (volume, calorific value and moisture content) incinerated by the plant. To meet strict emissions requirements, Doosan Lentjes developed the Circoclean® dry flue gas cleaning system, based on fluidised bed technology.
The company also offers precision steam turbines from partner business Doosan Škoda Power. These are capable of operating efficiently at varying levels of heat and steam, to enhance the efficiency of waste-to-energy units. Doosan Lentjes' waste-to-energy projects include:
Circulating fluidised bed (CFB) boilers
Doosan Lentjes designed and built the world's first CFB boiler featuring a fluidised bed heat exchanger (FBHE) in Germany in 1982. The company has produced designs up to almost 300MWe (~700MWth) with a capability of up to 500MWe (~1300MWth). The company's CFB boilers generate power at more than 100 plants around the world.
Doosan Lentjes is now working in partnership with Doosan Heavy Industries to develop supercritical steam CFB technologies with up to 600MWe of power.
Since mid-2013, Doosan Lentjes has been working with E.ON’s coal-fired Provence power plant in Gardanne, France to convert the existing coal-fired boiler, built and installed by Doosan Lentjes in 1992, into a biomass unit, and to replace the existing steam turbines. The biomass unit will generate electricity from forest chips, green residues and recovered wood and is expected to provide energy for 440,000 households.
Air quality control systems (AQCS)
Doosan Lentjes develops wet limestone flue gas desulphurisation (FGD), seawater FGD and dry-circulating fluidised bed (CFB) technologies that allow power plants to meet strict emissions targets. It also supplies high and low pressure pulse jet fabric filters, and electrostatic precipitator dedusters.
