B&W Vølund’s highly efficient waste-to-energy plants obtain a total recovery of 99%. In existing plants our flue gas condensation can increase energy recovery by 20-25%. Improved revenue, reduced greenhouse gas emissions, and a more positive image are three of the benefits that come from extended energy recovery by condensation of the hot flue gases.
In addition, energy recovery offers an economic incentive since the generated heat can be sold and, at the same time, the overall flue gas treatment is improved.
Maximized energy recovery makes sense, financially and environmentally
In Scandinavia most waste-to-energy plants are equipped with flue gas condensers. These are often in combination with heat pumps that will enhance the energy recovery even further. As a supplier of advanced thermal waste treatment systems, our subsidiary Götaverken Miljö has delivered such equipment to a number of waste-to-energy plants in Sweden and Denmark, countries in the forefront of environmental installations.
Flue gas condensation increases energy recovery by 20-25%
The condensation of flue gas in both heat exchangers and absorption heating pumps is affording huge gains in energy recovery.
The system condenses the flue gas in the washing tower by cooling the gas, extracting the heat, and sending it to the district heating grid. The extra heat extraction provided by the added absorption heating pump provides a 20-25% improvement in energy recovery from the waste. For this reason, the investment quickly pays for itself. The system can be implemented in existing plants.
Götaverken Miljö has delivered highly efficient flue gas condensation systems to a number of waste-to-energy and biomass-fired plants.
