Abstract
Disclosed is a system for producing electricity, the system comprising a chemical recovery boiler adapted to supply superheated steam to a steam turbine driving a generator, the chemical recovery boiler comprising a first flue discharge channel with a first heat exchanger arrangement; and a lime kiln comprising a second flue discharge channel with a second heat exchanger arrangement; and a circulation for heat transfer medium between the said heat exchanger arrangements. Also disclosed is a method for producing electricity, wherein said heat transfer medium is circulated between said heat exchanger arrangements such that thermal energy may be transferred from the flue gases in the first flue charge channel and/or the second flue discharge channel into the feed water of the chemical recovery boiler and/or into a heat-consuming process.
