Large CHP plants in pulp and paper industry Power plants operated according to steam demand of
the paper machine or pulp mill Electricity produced by back-pressure steam turbine Total efficiency = (electricity + heat) / fuel energy > 80% Fuels:
Mills own side products(bark, rejects, sludge)
Forest fuels from companysown wood collection
Additional fuels purchasedto cover the demand Nordic Countries:
peat, coal + oil/gas as back-up Central Europe: mainly gas
