In July 2007 a contract was signed with Söderenergi AB for delivery of a complete flue gas condensation plant to the new boiler at Igelsta Combined Heat and Power plant. The boiler is fired with biomass of various types and has a capacity of about 240 MW of heat and electricity. The condensation gives an additional impressive 80MW in favourable operating conditions. The large heat recovery was made possible by Radscan technology with pre-heating of combustion air which effectively squeezes out the last energy from the flue gases before they are emitted into the atmosphere.
The delivery consists of condensers, rotary pre-heater, stack and condensate treatment plant with Micro Filtration, Ultra Filtration, Reversed Osmosis, Electro Deioniser and ammonia removal (NH4). The delivery also includes boiler make-up water purification.
