Flue gas cooler at Sweden’s energy plant
In November 2017, Thermax’s Danish subsidiary Boiler works installed a flue gas cooler at an energy plant of Sweden’s largest producer of renewable energy, Vattenfall, in Uppsala, Sweden.
The combined heat and power plant utilises excess heat from waste incineration plants and other sources to generate electricity and produce district heating.
Flue gas coolers are special heat recovery units where heat contained in waste gases is used to produce steam, or for energy conservation purposes. The system supplied by Boilerworks cools down flue gases in the waste incineration plants. The cooler, located before the chimney, lowers the temperature of flue gases from about 160°C to 70-80°C.
The contract bagged in April this year, included the supply, manufacture, delivery and installation of the unit. The installation successfully tackled the challenge of removing the existing old cooler and installing the new one within 48 hours, minimising losses in the production of power and heat.
