Andritz and Metsä Fibre successfully perform fossil fuel reduction programme at Joutseno mill, Finland
Austria-headed international technology group Andritz AG and Finnish forest industry major Metsä Group have announced the successful collaboration on a programme to maximize the reduction of fossil fuel usage, as well as improve the overall performance of the lime kiln, at Metsä Fibre's Joutseno mill in Finland.
The goal of the programme, entitled “Gasification Plant 100% Utilization Rate”, was to maximize the availability of all equipment, including the wood processing plant, dryer, gasification plant, and lime kiln, as well as the lime kiln burner and its heat transfer system.
According to Andritz, as a result of the programme, the Joutseno mill has now replaced 95 percent of the natural gas being used in the lime kiln with biomass (bark) derived gas. Moreover, the quality of the lime product has markedly improved.
The cooperation between the two companies will continue with Overall Production Efficiency (OPE) agreements to further fine tune the systems.
The Joutseno 48 MW gasification plant is based on the Circulating Fluidized Bed (CFB) technology developed by Andritz. Other CFB references include a 65 MW CFB gasification plant supplied to Zhanjiang Chenming Pulp & Paper mill in China; which replaces the heavy fuel oil it used earlier in the lime kiln; and a repeat order from Chenming Group in 2015 with a 80 MW CFB gasification plant for its new greenfield pulp mill, Shouguang Meilun in China.
